Cathode Material Of Lithium Battery Fluorographene

Fluorographene is an important graphene derivative. Compared with graphene, fluorographene retained the lamellar structure of graphene although the carbon atoms were hybridized from sp2 to sp3. As a result, fluorographene has not only large specific surface area, at the same time due to the introduction of fluorine atoms, the surface energy of graphene was greatly reduced, the property for hydrophobic and oleophobic was greatly enhanced, while the thermal stability, chemical stability and corrosion resistance were largely improved. Due to its unique properties, fluorographene can be widely used in the fields of anti-wear lubrication, high temperature corrosion resistant coating, at the same time, due to its wider bandgap, fluorographene has potential applications prospect in nano-electronic devices, photoelectronic devices, thermoelectric devices and other fields. In addition, because the fluorocarbon materials have fairly developed specific surface and pore structure and unique conductivity, the lithium primary batteries will have large contact interface with electrolyte and fast lithium ion diffusion speed, when fluorographene used as cathode material of lithium batteries. These lithium primary batteries have the advantages of high energy density, high discharge voltage, stable discharge curve, wide operating temperature, extremely long shelf life, which has great application potential in the aerospace and high-end civil field.

Shandong Zhongshan Photoelectric Materials Co., Ltd. is a high-tech enterprise invested and established by Shandong Zhongshan Group Co., Ltd., which integrates R&D, pilot test and industrialization. Zhongshan Photoelectric Materials Co., Ltd. There is a research and development team of more than 200 people, mainly including professors,postdocs,doctors, researchers, masters and undergraduates. In just a few years, the company has made a number of innovative technological achievements.In the last three years, we have applied for more than 50 patents and granted 30 invention patents.

The company set up a 5,000 square meters of R&D pilot platform, including a number of complete supporting facilitiesfunc advanced tion of test and pilot devices, such as special functional fluorinated carbon materials, High Pure Fluorine gas, semiconductor materials(high pure electronic gas/ electronic chemicals), Lithium Battery electrolytes and additives,high specific energy battery, thermal battery and related materials, photoelectric materials, stable isotope and its derivative materials, fluoridated biomedical materials, etc. The company can conduct a number of innovative rr&d tests and pilot new materials and equipment related areas. The company has established an advanced analysis and test center for R&D and production of all the projects.

In the meantime,the company has established the first large-scale fluorographene production line and functional fluorocarbon material performance assessment laboratory worldwide, and it is now the only manufacturer capable of producing and supplying high quality fluorographene in large quantities both domestically and internationally.
