In recent years, with technological progress and demand growth, the application fields of fluorine products have begun to penetrate from traditional industries to new fields such as electronics, energy, environmental protection, and biomedicine. In the field of new energy, fluorine chemical products have now become one of the key materials in the field of new energy such as lithium-ion batteries, fuel cells, solar cells, wind energy, and nuclear energy. Fluorochemical Industry Chain The middle and upper reaches of the fluorine chemical industry chain are mainly hydrofluoric acid and aluminum fluoride, and it extends into four categories of fluorine refrigerants, fluorine-containing polymers, fluorine-containing fine chemicals and inorganic fluorides. The end products are air conditioners and automotive applications. Refrigerants, industrial fluorine-containing new materials, extremely important electronic grade hydrofluoric acid in the semiconductor field, etc. In the fluorine chemical industry chain, as the depth of product processing increases, the added value and profit rate of products increase geometrically. At present, products such as fourth-generation fluorine refrigerants, fluorine-containing fine chemicals, and fluorine-containing polymers are all in their infancy and growth stages.

Fluorinated graphite is a kind of graphite intercalation compound produced by the direct reaction of carbon and fluorine. Its chemical structure can be represented by (CFx)n. Where X is an indeterminate value, and the size is 0<X<1.25. The properties of fluorinated graphite vary with the ratio of carbon to fluorine in the molecular formula. CF (1-1.25) is called high fluorination graphite, CF (0.5-0.99) is called low fluorination graphite. As the fluorine content increases, the color of graphite changes from grayish black to snow white. The degree of fluorination is The higher the lubricating performance of fluorinated graphite, the better. Fluorinated graphite has high thermal stability and is an electrical and thermal insulator. It is sintered in a small rotary kiln of Fenggu lithium battery powder and is not corroded by strong acids and alkalis. Its lubricating performance exceeds that of molybdenum disulfide and flake graphite. Tests have proved that its wear life is better than molybdenum disulfide at any temperature. As an additive of lubricating wax, graphite with high degree of fluorination can significantly increase the supporting load of the parts and reduce the surface temperature of the lubricating parts. Because the graphite has a layered structure, the carbon atom spacing in the layers is 1.4?, which are firmly connected by covalent bonds, and the carbon atom spacing between the layers is 3.35?, and there is only a weak van der Waals force between the layers, so the graphite layers are easy to insert Dissimilar substances form graphite intercalation compounds. When the graphite interlayer insert is fluorine, the graphite interlayer compound that can be formed is fluorinated graphite. Fluorinated graphite has different characteristics according to the difference in the fluorine-to-carbon ratio, but only fluorinated graphite (CFx) n with a fluorine-to-carbon ratio of not less than 1 has good chemical and thermal stability. In this kind of fluorinated graphite, fluorine forms a covalent bond with the 2Pz electrons of carbon atoms, the distance between carbon atoms in the layer is increased to 1.52?, and the layer is bent, which loses the conductivity of graphite and becomes an insulator. The electronegativity of the interlayer stretches the interlayer carbon atom distance from 3.35? to 7.O8?, which greatly reduces the interlayer energy and significantly improves the lubricating performance. (CFx) n-Li battery, widely used in computers, mobile phones, clocks, cameras, camcorders and integrated circuit storage, the battery has the following characteristics: (A) high voltage and current density; the battery has high The voltage and current density. (B) High utilization rate and excellent potential flatness: The battery generates highly conductive carbon, so its utilization rate is 100%. Since the internal resistance does not increase, the discharge potential can be stabilized at the end of discharge. (C) Good storage performance and long duration. Graphite fluoride is stable both electrochemically and thermodynamically, and its self-generation rate is also very small, 0.5% per year. It can be used in a wide temperature range and is generally used. The temperature range is -20~700℃. The type of fluorinated graphite is generally related to the crystallinity and crystal orientation of carbon materials, which indicates the prospects for the production of high-energy batteries. At present, fluorinated graphite batteries have been widely used in foreign countries, including button type, coin type, and cylindrical type. , There are several types of needles.

Introduction to Electronic Gas Electronic special gas (referred to as electronic special gas) is an important branch of special gas, and it is an indispensable raw material for the production of electronic industries such as integrated circuits (IC), flat display devices (LCD, LED, OLED), and solar cells. Generally, the semiconductor production industry divides gases into two types: common gases and special gases. Among them, the commonly used gas refers to a centralized supply and uses a lot of gas, such as N2, H2, O2, Ar, He and so on. Special gas refers to some chemical gases used in the process of semiconductor production, such as extension, ion injection, blending, washing, and mask formation, that is, electronic gases in the gas category, such as high-purity SiH4, PH3, AsH3, B2H6, N2O, NH3, SF6, NF3, CF4, BCl3, BF3, HCl, Cl2, etc. In the IC production process, there are almost 100 kinds of electronic gases used, and about 30 kinds are common in the core section. It is these gases that make silicon chips have semiconductor properties through different manufacturing processes, which in turn determine the performance, integration, and yield of integrated circuits. Even if a certain specific impurity exceeds the standard, it will cause serious quality defects. In severe cases, the entire production line will be contaminated due to the diffusion of unqualified gas, and even the production will be completely paralyzed. Therefore, electronic gas is a key basic material in the electronic manufacturing process, and it is a veritable "blood" of the electronic industry. The manufacture of integrated circuit chips requires the use of a variety of electronic gases, including silicon group gases such as silane, doping gases such as PH3, etching gases such as CF4, metal vapor deposition gases such as WF6, and other reactive gases and cleaning gases. In the preparation process of electronic grade silicon, the electronic gases involved include SiHCl3, SiCl4 and so on. The chemical vapor deposition (CVD) process on the surface of silicon wafers mainly involves SiH4, SiCl4, WF6 and so on. In the wafer manufacturing process, some processes involve the application of gas etching processes, also called dry etching. The electronic gases involved include CF4, NF3, HBr, etc. The amount of such etching gases is relatively small, and the etching process requires Together with related inert gases Ar, N2, etc., the etching degree is uniform. The doping process is to dope the required impurities into a specific semiconductor area to change the electrical properties of the semiconductor. The electronic gases involved include trivalent gases such as B2H6 and BF3 and pentavalent gases such as PH3 and AsH3. The main types of electronic gases used in the flat-panel display industry include silicon group gases such as silane, doping gases such as PH3, and etching gases such as SF6. In the thin film process, SiO2, SiNx and other thin films are deposited on the glass substrate by chemical vapor deposition, and the special gases used are SiH4, PH3, NH3, NF3 and so on. In the dry etching process, the substrate is selectively etched in a plasma gas atmosphere. Usually use SF6, HCl, Cl2 and other gases. Solar cells can be divided into crystalline silicon solar cells and thin-film solar cells. In the production of crystalline silicon cells, the diffusion process uses POCl3 and O2, the anti-reflection layer plasma enhanced chemical vapor deposition (PECVD) process uses SiH4 and NH3, and the etching process uses CF4. For thin-film solar cells, diethyl zinc (DEZn) and B2H6 are used in the process of depositing transparent conductive films, and silane is used in the process of depositing amorphous/microcrystalline silicon.

(1) Introduction of Lithium Battery Lithium-ion batteries use carbon materials as the negative electrode and lithium-containing compounds as the positive electrode. There is no metal lithium, only lithium ions, which is a lithium-ion battery. Lithium ion battery refers to the general term for batteries with lithium ion intercalation compound as the cathode material. The charging and discharging process of lithium ion batteries is the process of intercalation and deintercalation of lithium ions. In the process of intercalation and deintercalation of lithium ions, it is accompanied by the intercalation and deintercalation of electrons equivalent to lithium ions (the positive electrode is usually represented by insertion or deintercalation, and the negative electrode is represented by insertion or deintercalation). During the charging and discharging process, lithium ions are intercalated/deintercalated and intercalated back and forth between the positive and negative electrodes, which is vividly called the "rocking chair b attery". Lithium ion battery is a kind of rechargeable battery, which mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when recharging the battery, Li+ deintercalates from the positive electrode and inserts into the negative electrode through the electrolyte, the negative electrode is in a lithium-rich state; the opposite is true during discharge. Generally, batteries that use materials containing lithium as electrodes are representative of modern high-performance batteries. Nowadays, lead-acid batteries, nickel-hydrogen batteries and lithium batteries are more common in the rechargeable battery market. The positive electrode of the lead-acid battery uses lead dioxide, the negative electrode uses spongy lead, and the electrolyte is a dilute sulfuric acid solution. The basic voltage of each unit is 2V. Reliable performance, low price, mature technology, but heavy quality, poor overcharge and overdischarge performance, easy to self-discharge, unsatisfactory specific energy, energy density and lifespan, difficulty in rapid charging, and heavy metals contained in waste batteries. It has been gradually replaced by other high-energy batteries. It is unlikely that it will be the mainstream power supply for energy vehicles. The laboratory data of the main technical indicators of nickel-metal hydride batteries are all lower than that of lithium batteries, and there is basically no room for improvement in theory. Although China is rich in hydrogen storage materials, its refining technology is not high, battery pack consistency is poor, and technical problems have not been broken so far. Moreover, the cost of nickel-hydrogen batteries has remained high. The battery of choice for the first generation of electric vehicles, the power battery is relatively mature, commercial feasibility is strong, but the space is not large. In the long run, it will be replaced by lithium batteries. Lithium batteries have large specific energy, high specific power, high charging and discharging efficiency, high power output density that can be quickly charged, and no memory effect. However, the preparation of lithium is more difficult, management and use are more complicated, and strict safety measures are required. At present, typical applications include notebook, mobile phone and other consumer electronic battery requirements. The migration from 2G networks to 3G networks, and then to 4G networks and 5G networks, has played a major role in driving the demand for lithium batteries. New energy vehicles will bring explosive demand for lithium-ion power batteries. Batteries are the heart of new energy vehicles and determine the competitiveness of new energy vehicles. The development strategy of new energy vehicles with hybrid power, plug-in hybrid power, and pure electric vehicles as the main power modes has become the consensus of the industry. At present, various countries, major enterprises, and related supporting systems are working hard to seize the commanding heights of the industry. The main application areas of lithium-ion energy storage batteries are smart grids, distributed power systems, wind and solar power generation systems, UPS power supplies, communication base stations, military backup power supplies, solar lights and lawn lights. Lithium batteries also have important applications in the field of energy storage. First of all, they can solve the problem of peak and valley regulation of grid electricity. Secondly, clean energy such as wind, solar, and tidal energy are all intermittent energy sources. Potassium energy storage equipment cooperates with the use of the above clean energy to store energy during power generation and release energy during the intermitte

The Nobel Prize in Chemistry was awarded to John Goodenough, University of Texas at Austin, Stanley Wittingham, State University of New York at Bingham, and Akira Yoshino from Asahi Kasei Co., Ltd. in recognition of their research and development of lithium-ion batteries. Outstanding contribution. So, how are lithium batteries developed? What will be the future development? 1 There is no mobile smart life without lithium batteries We have already lived in a "rechargeable world", but it is the lithium battery that truly brings the portability of electronic devices and opens up modern mobile life. It can be said that if there is no lithium battery, there will be no mobile smart life we are now. Lithium batteries are widely used in various fields from mobile phones to notebook computers because of their light weight, rechargeability, powerful functions and portability. It is used worldwide to power portable electronic devices, and we use these portable electronic devices for communication, work, study and entertainment. Lithium batteries have also promoted the development of long-lasting electric vehicles and energy storage from renewable energy sources (such as solar and wind energy), laying the foundation for a wireless (mobile), fossil-fuel-free society. It can be said that as an energy storage device, lithium-ion batteries have completely changed human life. The Nobel Prize in Chemistry was awarded to three scientists in the field of lithium battery. It is a recognition for every lithium battery practitioner who has made contributions to the commercialization of lithium batteries from scratch and from the laboratory to the commercialization of lithium batteries. It is a recognition that they are still engaged in lithium battery research. Hezhi is an incentive for people who continue to promote the development of a clean and portable society. 2 The oil crisis directly contributed to the research and development of lithium batteries In the 1970s, the oil crisis directly contributed to the research and development of lithium batteries. The American oil giant Exxon judged that oil resources, as a typical non-renewable resource, will face exhaustion in the near future, so they formed a team to develop the next generation of energy technology that replaces fossil fuels. The lithium battery is one of the new batteries proposed by people. At that time, Stanley Wittingham, who worked for Exxon, proposed a new material titanium disulfide as a positive electrode material, which can store lithium ions between molecular layers. When it is matched with the metal lithium negative electrode, the battery voltage is as high as 2V. However, due to the high activity of the metal lithium negative electrode, which brings great safety risks, this kind of battery has not been promoted. But scientists have not given up on exploration. Since the problem lies in the electrode material, perhaps replacing the electrode can solve the problem. Goodenough, who was the director of the Inorganic Chemistry Laboratory at the University of Oxford in the UK at the time, concluded that using metal oxides instead of sulfides as the positive electrode can achieve higher voltages and improve the performance of lithium-ion batteries. In 1980, Goodenough used lithium cobalt oxide as the positive electrode of the battery, which could increase the battery voltage to 4V. The emergence of lithium cobalt oxide is a great breakthrough in the field of lithium-ion batteries, and it is still the main cathode material for portable batteries. 3 The first commercial lithium battery appeared in the 1990s However, due to the unstable characteristics of metal lithium negative electrodes, the safety of lithium-ion batteries was still a serious problem at that time. In 1985, Japanese scientist Akira Yoshino used petroleum coke instead of metal lithium as the negative electrode and lithium cobalt oxide as the positive electrode, inventing the first commercial lithium-ion battery. In 1991, Sony Corporation of Japan released the first commercial lithium-ion battery. After more than 30 years of industrial development, the energy density, cost and safety of lithium-ion batteries have made great progress, and have penetrated into all aspects of our lives. Among the currently widely used commercial lithium batteries, lithium ions are randomly "chained back and forth" in the "master" home who uses special layered materials as the positive and negative electrodes of the battery to complete the charge and discharge of the battery. It should be pointed out that although the "stop-in" process of lithium ion insertion and extraction does not affect the material structure of the "master" at home, the whole process is still a chemical reaction rather than a physical reaction. 4 Lithium batteries still have a lot of room for development This year's Nobel Prize in Chemistry awarded to the field of lithium batteries is a huge affirmation and encouragement to this industry. Lithium batteries are still facing many arduous challenges from the birth and development to the application and promotion. Since Sony`s commercial production of the first batch of lithium-ion batteries in 1991, the above-mentioned [rocking-chair batteries" that [dropped in" with lithium-ion batteries have become the most promising and fastest-growing market. However, restricted by the principle of lithium-ion batteries, the energy density of lithium-ion batteries in the existing system has dropped from an annual growth rate of 7% to 2%, and is gradually approaching its theoretical limit. On the contrary, with the progress of society, people's demand for portable and clean life becomes stronger. The use of electrode materials with less mass to store more electricity is expected to build a lithium ion battery with higher energy density. The specific capacity of metallic lithium is as high as 3860mAh/g, which is the ultimate material for constructing high specific energy batteries. However, if lithium metal is directly used as the negative electrode material of the battery, there is always a "tarsus maggot"-dendrite. In the face of this "enemy" that causes potential safety hazards for lithium batteries, scientists from all over the world are making unremitting efforts. 5 Dealing with the "dendrite", the enemy of lithium battery safety As we all know, a battery is divided into a positive electrode, a negative electrode, and an electrolyte. Electric current is generated through an oxidation-reduction reaction. When discharging, ions flow from the negative electrode to the positive electrode, and when charging, they flow from the positive electrode to the negative electrode. For lithium batteries, lithium will be oxidized into ions during discharge and enter the electrolyte and finally reach the positive electrode; when recharged, these lithium ions will redeposit on the surface of the lithium metal negative electrode. However, this deposition is often uneven. With the frequent use of lithium batteries, needle-like or dendritic lithium dendrites will grow on the surface of lithium metal. If the dendrite grows too long, it will break and will no longer participate in the reaction, causing irreversible capacity loss to the battery system. The most dangerous thing is that the grown dendrite will pierce the separator between the positive and negative electrodes of the battery, causing a short circuit. Buried potential safety hazards of battery overheating, spontaneous combustion or explosion. In the field of lithium battery, how to achieve "both fish and bear's paw"? How to achieve a higher energy density, safer, and faster charging energy storage process by proposing new principles, new systems, and new methods? These are the challenges facing the lithium battery field in the future. In this situation, many new battery systems such as lithium-sulfur batteries, lithium-air batteries, and sodium-ion batteries have emerged. The continuous production of new materials has also brought new opportunities to the development of these new systems. Further reading my country's lithium battery researchers are carrying out a lot of original work Countries such as China, the United States, Japan, South Korea, Germany, and the United Kingdom have formulated their own battery development strategies in order to promote the innovation of battery principles and the development of core technologies to support the sustainable development of contemporary society. With the support of the state and society, my country's lithium battery researchers continue to carry out scientific research around the unchanging "initial heart" of high-efficiency energy storage. At present, the mainstream research direction in the field of lithium batteries is still focusing on finding safer and more efficient anode materials. The Tsinghua University research team led by the author has carried out original scientific research in the fields of lithium metal negative electrode nucleation and dendrite-free growth since 2013. Studies have found that adding a lithium-philic nitrogen-doped carbon skeleton to the lithium metal negative electrode allows free lithium ions in the battery to start charging, just like a tadpole looking for a mother, and preferentially rush to the frog mother-the nitrogen-doped site. A "small group" of evenly distributed lithium metal is formed in the battery; during the charging process, the "small group" of "tadpoles and mother frogs" continues to "hug together." This uniform deposition behavior can avoid the dendritic growth of metallic lithium that has been caused by less nucleation in the past. The paper based on the above results was selected as the cover of the top chemistry journal "German Applied Chemistry" in 2017. This year, it was also selected for the "Beijing Area Popular Academic Papers" selection activity sponsored by the Beijing Science and Technology Association. Based on the above-mentioned energy chemical mechanism, the research team further designed a carbon-lithium composite anode. These composite metal lithium anodes not only avoid "dangerous dendrites", but also exhibit excellent electrochemical performance, which effectively improves the utilization efficiency and safety of metal lithium anodes, and also provides secondary batteries based on metal lithium. New practical exploration ideas and broader application prospects. In addition to lithium batteries, the use of sodium, potassium, aluminum, and zinc plasmas and the development of new principles of energy chemistry are also expected to propose new energy storage devices with unique properties. In addition to electrochemical energy storage, the use of other energy storage and conversion methods and new energy carriers is expected to build a disruptive energy storage technology to meet the new needs of the society for energy storage equipment in the future.

DETROIT (AP) - Although General Motors will build Honda's first two fully electric vehicles for North America, the Japanese automaker plans to change course and manufacture its own later this decade. Company officials say they're developing their own EV architecture, and after two GM-made EVs go on sale in 2024, Honda will start building its own. [It's absolutely our intention to produce in our factories," Honda of America Executive Vice President Dave Gardner said, adding that Honda has developed battery manufacturing expertise from building gas-electric hybrids. [We absolutely intend to utilize that resource." Honda and GM have been partners on hydrogen fuel cell and electric vehicles. Earlier this year they announced that GM would build one Honda SUV and one Acura SUV using its Ultium-branded electric vehicle architecture and battery system. The company said the Honda SUV would be named the Prologue, and that both SUVs will have bodies, interiors and driving characteristics designed by Honda. But after those two, Honda plans its own manufacturing for most of a series of electric vehicles, although it hasn't determined if it will use GM components. Gardner says sales projections for the Prologue are between 40,000 and 150,000 per year, but he didn't say when those numbers would be reached. In April, the company said it plans to phase out all of its gasoline-powered vehicles in North America by 2040, making it the latest major automaker with a goal of becoming carbon neutral. Honda wants 40% of North American vehicle sales to be battery or fuel-cell powered by 2030, and 80% of all vehicles sold to run on batteries or hydrogen by 2035. Honda initially had planned to meet stricter government fuel economy and pollution standards by adding hybrids to improve internal combustion engines. But regulatory actions across the world to combat climate change, including proposals from U.S. President Joe Biden, have moved the company more toward electric vehicles, Gardner said. Battery-electric vehicles accounted for less than 2% of U.S. new-vehicle sales last year, but analysts are predicting huge growth as automakers roll out new models. The consulting firm LMC Automotive expects nearly 359,000 to be sold this year, passing 1 million in 2023 and hitting over 4 million in 2030. Still, that's roughly one-quarter of annual new vehicle sales.

2016 China International Graphene Innovation Conference and 2016 China international advanced carbon materials Application Expo were held in Qingdao International Convention and Exhibition Center from September 22 to 24, 2016. Shandong Zhongshan photoelectric materials Co., Ltd. participated in the Innovation Conference with a delegation of 6 people led by Chairman Li Zhe, and participated in the exhibition with a series of advanced special fluorocarbon materials such as Fluorinated Graphite, fluorinated fossil graphene and Fluorinated Carbon Nanotubes. Our products won the silver medal of this Expo. During this meeting, we found that many people from all walks of life showed far more interest in our products than we expected, and the market prospect of fluoro fossil merene materials is far broader than we expected. In the face of such a huge potential market, our only choice is to overcome all difficulties and accelerate the industrialization process, build Zhongshan optoelectronics into the world's first fluorine fossil graphene industrialization base and product supplier, seize the market opportunity and open up the industrial application field of graphene materials. As the first company to enter the pilot test of research and development of fluorofossil graphene materials, Zhongshan optoelectronics has completed the pilot test of production technology, applied for three national invention patents, and has fully independent intellectual property rights. We must give full play to our advantages in the starting line and further accelerate the industrialization process of the project. We plan to complete the construction of the first demonstration production line with an annual output of 15 tons of lithium-ion battery grade fluorofossil merene in November 2016 and put it into production in December 2016. Through the operation of demonstration line, optimize production process, improve product quality and reduce production cost. In the future, we can continue to add production lines according to the market demand, and plan to form an annual production scale of 100 tons in 2017. In addition, the company will follow the good situation of vigorously promoting the development of graphene industry in China, and conduct more in-depth research and product promotion in the application field of fluorofossil graphene materials. It is planned to enter the national torch Qingdao graphene and advanced carbon material characteristic industrial base next year, set up R & D and product promotion experience center, and strengthen cooperation with major universities and research institutions at home and abroad. In this paper, we will continue to study the application of fluorinated graphene series materials in lithium Primary Battery, and expand its application research in lubrication, corrosion protection, semiconductor devices and other fields. It is planned to establish marketing and research centers in Beijing, Shanghai, Shenzhen and other places as well as overseas in the next three to five years, so as to expand our business scope and expand overseas markets. This time, I participated in the China International Graphene Innovation Conference and product exhibition, and gained a lot. First of all, the huge market demand enables us to understand the broad development prospects of fluorofossil merene materials and the expectation for our products. Secondly, as the first enterprise to display and promote a series of fluorocarbon materials such as fluorocarbon in the international exhibition, we make the industry begin to understand Zhongshan photoelectric, which is conducive to the future market of Zhongshan photoelectric products. Third, through face-to-face communication with peers, we have a deeper understanding of the current situation and future development trend of graphene material industry, which is conducive to our correct and reasonable development plan. Finally, we recognize the urgency of promoting the project, and we will spare no effort to promote the progress of the project, realize the industrial production at the fastest speed, occupy the market first, and meet the urgent needs of the country and Society for the products.

With the development of technology, semiconductor chips have expanded from computers and automobiles to toothbrushes and drum dryers. Demand for chips continues to exceed supply, and car manufacturers are no longer the only companies feeling the pressure. Many companies, especially those in China, are increasing their chip inventory in an attempt to tide over the difficulties, but this makes it more difficult for other companies to obtain chips. In the past few weeks, the severity of the global chip shortage has risen by a notch, and it now appears that millions of people will be affected. Alan Priestley, an analyst at Gartner, told CNBC that ordinary people on the street will inevitably be affected by the shortage of chips in some form, which means that they cannot get some goods, or the prices of goods are slightly higher. South Korean technology giant Samsung said last week that chip shortages are impacting the production of TVs and home appliances, and LG also admitted that shortages are a risk. Samsung said that due to the global semiconductor shortage, Samsung has also encountered some impact, especially around certain packaged products and display production. Samsung is discussing supply plans with retailers and major channels so that Samsung can allocate parts to products that are more urgent or prioritized in terms of supply. Koh Dong-jin, Samsung's co-CEO and head of mobile business, said at the shareholders' meeting in March that the supply and demand of chips in the IT industry are seriously out of balance. At the time, the company stated that it might skip the release of the next GalaxyNote smartphone. According to the [Financial Times" report, LG said that it is paying close attention to this situation, because if the problem is prolonged, no manufacturer can get rid of this influence. Low-margin processor production has also been hit, such as those used to weigh clothes in washing machines or toast bread in smart toasters. Although most retailers can still buy these products, they may face supply problems in the coming months. According to the Washington Post, even dog washing companies are suffering losses. According to reports, CCSI, a company that manufactures electronic dog washing kiosks in Illinois, was recently informed by its circuit board supplier that there was a shortage of chips and could no longer be supplied. According to reports, the company switched to a different chip and adjusted its circuit boards, increasing costs in the process. The automotive industry is still hit hardest. The automotive industry relies on chips from computer management of engines to driver assistance systems. Companies such as Ford, Volkswagen and Jaguar Land Rover have closed factories, laid off workers and cut car production.

Fluorinated graphene is a derivative of graphene. Fluorinated graphene has a unique crystal structure, good stability and corrosion resistance, high mechanical strength and good biocompatibility. At present, the applications of fluorinated graphene are mainly concentrated in lithium batteries, photodetectors, modified resin materials, and medical fields. In 2004, Geim of the University of Manchester in the United Kingdom reported on the discovery of single-layer fluorinated graphene in "Science", which opened the upsurge of fluorinated graphene research. At present, the research and development of fluorinated graphene is still in its infancy. The initial preparation method of fluorinated graphene is that scientists use XeF2 and plasma CF4 and SF6 to directly fluoride graphene. Subsequently, new synthetic methods continue to appear, which can be divided into chemical methods and physical methods. Chemical preparation of fluorinated graphene has the advantages of simple operation, controllable reaction, and large specific surface area, but the gas is expensive, has safety risks, and requires professional equipment. The laws of physics have low requirements on the environment and are mild and controllable, but the physical laws are small in size and cause serious damage. The chemical method is a method that utilizes the reaction between fluorinating agent, graphite and fluorine gas. Because F2 is expensive and difficult to operate, many studies have made improvements to it, that is, the reaction of graphene with XeF2 or CF4 at room temperature Preparation of fluorinated graphene. According to the "2019-2023 China Fluorinated Graphene Market Feasibility Study Report" issued by the New Sijie Industry Research Center, the current domestic chemical methods to study fluorinated graphene are mainly Tianjin Polytechnic University, Southwest University of Science and Technology, and Northwest Industrial University, Sichuan University, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, Shanghai Institute of Organic Chemistry, Hunan Elementary Code Graphene Research Institute, Chinese Academy of Sciences, Ocean King Lighting Technology Co., Ltd., Hubei Zhuoxi Fluoride Co., Ltd., Shandong Zhongshan Optoelectronic Materials Co., Ltd. Wait. The physical method is divided into mechanical exfoliation method and liquid phase exfoliation method, that is, fluorinated graphene is prepared by liquid phase exfoliation or mechanical exfoliation of fluorinated graphite. There are few domestic institutions that conduct physical preparation of fluorinated graphene, mainly including the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences. New Thinking Investment analysts pointed out that fluorinated graphene has a wide range of potential applications and has good development value. In the field of lithium batteries, fluorinated graphene is considered to be an ideal electrode material for lithium-ion batteries. The use of fluorinated graphene can not only improve the electrochemical performance of lithium-ion batteries, but also is expected to improve the thermal conductivity of electrode materials and even the entire battery. In the field of photodetectors, fluorinated graphene can be transferred to different substrates. If fluorinated graphene is transferred to a flexible substrate, a flexible photodetector device with the characteristics of bendability, impact resistance and light weight can be realized. . In the medical field, fluorinated graphene can be used in biosensors, tissue engineering, bioimaging, medical diagnosis and treatment, etc.

Electronic special gas is widely used in high-tech industries such as semiconductors, microelectronics and related solar cells, or used for thin film deposition, etching, doping, passivation, cleaning, or as a carrier gas, protective atmosphere, and so on. As semiconductor and microelectronics technologies are developing toward higher performance and higher integration, higher and higher requirements are put forward for the purity of electronic special gas, and the purification of electronic special gas is becoming more and more critical and important. The domestic ultra-high purity purification technology mainly relies on imports, and its own technical level (6N) is far behind the international advanced level (8-9N). A well-known domestic project will design and develop a series of high-efficiency, high-capacity, high-selectivity, and low-cost new nano-purifiers, which will affect 5 series of MO sources, inert gases, hydride gases, reactive gases, and corrosive gases. A variety of electronic special gases are purified at the end to increase the purity of electronic special gases from ppm to ppb and ppt levels, and minimize the impact of special gas transmission and control systems on gas purity, thereby greatly improving process capacity and reducing products Defects, increase the yield of the process, and meet the needs of the next generation of semiconductors, microelectronics and related high-tech development. Zhongshan Optoelectronics will form an ultra-high-purity electronic special gas purification technology with independent intellectual property rights to solve the localization of the core technology of ultra-high-purity electronic special gas purification. From the perspective of the global market, the top five companies of Air Chemical Industry Group, Air Liquide Group, Japan Dayang Nissan Co., Ltd., Praxair Group of the United States, and Linde Group of Germany account for more than 90% of the market share. In the Chinese market, the five giants also occupy nearly 90% of the market share, and the monopoly pattern is obvious. Chongshan Optoelectronic Materials Co., Ltd. currently mass-produces germanium tetrafluoride, xenon difluoride, chlorine trifluoride, trifluoromethyl iodide, nitrogen trifluoride, germanium tetrafluoride, titanium tetrafluoride, silicon tetrafluoride, hexafluoride Fluorine-containing high-purity electronic special gas such as tungsten fluoride, molybdenum hexafluoride, and perfluorobutadiene.

The application of fluorine chemistry in medicine can be traced back to the 1950s. In 1953, Dr. Josef Fried and Dr. Emily Sabo prepared a series of cortisone acetate derivatives and found that as a glucocorticoid, the anti-inflammatory activity of 9-fluoro substituted cortisone acetate was more than 10 times higher than the corresponding parent compound. It is the first public demonstration that the introduction of fluorine atoms in a specific position of a drug molecule can improve its biological activity. In 1957, Dr. Robert Duczynski and others completed a series of studies on the synthesis, characterization and clinical trials of the nucleic acid antagonist 5-fluorouracil, which contributed to a breakthrough in cancer treatment. The introduction of fluorine atoms or fluorine-containing groups into drug molecules can change the permeability and metabolic stability of drug molecules, adjust their pKa and fat solubility, and affect the absorption and distribution of drug molecules and the interaction with biological targets. Common means of drug screening. Among the 38 small molecule drugs approved by the FDA in 2018, 18 are fluorine-containing drugs, such as Biktarvy for the treatment of HIV infection and Erleada (apalutamide) for the treatment of non-metastatic castration and anti-prostate cancer. However, with the development and popularization of fluorine-containing drugs, people still need to consider their chemical stability in the human body and the impact of metabolites produced by enzymes on the human body, as well as safety issues during administration and treatment. The carbon-fluorine bond has a high bond dissociation energy (BDE), indicating that the carbon-fluorine bond is not easy to split uniformly. However, under the action of nucleophiles and drug-metabolizing enzymes in the human body, certain types of C-F bonds can easily generate fluoride anion species through heterocleavage. Early clinical data showed that voriconazole, a broad-spectrum antifungal drug, can increase fluoride levels in human plasma. Fluoride has a strong affinity for Ca2 in bones, which can cause bone strength reduction, bone metabolism disorders, periostitis, osteochondroma and other diseases. Recently, Dr. Pan Yue from NIBR summarized the possible metabolic pathways of fluorine-containing drugs with different structures in the human body in the "ACS Medicinal Chemistry Letters". Some drug molecules can be decomposed to produce fluoride and fluorine-containing toxic metabolites. Feasible suggestions are put forward for the improvement. Here, medicinal chemistry researchers are reminded to think carefully when designing related structural drugs. At present, our company can produce a variety of high-purity fluorine-containing biomedical intermediate materials on a large scale: perfluorooctane, perfluorodecalin, perfluorooctyl bromide, perfluorooctyl ethyl acrylate, perfluorotripropylamine, all Fluorotributylamine, fluorosurfactant, etc.

The fluorinated graphene demonstration device can be used to develop and produce fluorinated graphite, fluorinated nanographite, fluorinated carbon nanotube, fluorinated fullerene, fluorinated graphyne, and fluorine with different degrees of fluorination, different uses, and different precursor structures. Chemical carbon fiber, fluorinated activated carbon, fluorinated carbon black, fluorinated diamond, fluorinated coke, fluorinated pitch and other series of functional fluorocarbon materials. Lithium carbon fluoride series cylindrical batteries, lithium carbon fluoride series soft pack batteries, and lithium carbon fluoride series button batteries have been widely used in automotive electronic products, instrument backup power supplies, smart sensor backup power supplies, etc., which have stringent battery requirements. Equipment and fields. Various high-purity electronic special gases and fluorine-containing pharmaceutical intermediate materials, such as: germanium tetrafluoride, trifluoromethyl iodide, perfluorobutadiene, perfluorooctyl bromide, perfluorooctane, perfluorodecalin, two Xenon fluoride, fluorine-nitrogen mixture (20%F2+N2), perfluorooctyl ethyl acrylate, etc., can all be produced on a large scale. Stable isotope materials such as boron 10 and boron 11 have also been introduced to the market recently, accelerating the implementation of the task of transforming scientific and technological achievements.
