Fluorinated graphite is an important functional material, and its preparation methods mainly include direct synthesis, catalytic synthesis, synthesis in a vertical vibrating reactor, and electrolysis. The direct synthesis method involves heating solid carbon and gaseous fluorine within a certain temperature range, but it has safety hazards and low yield issues. The catalytic synthesis method involves adding trace amounts of metal fluorides as catalysts to the reaction system of graphite and fluorine, which can enhance the conductivity. Fluorinated graphite also exhibits good hydrophobic and oleophobic properties, as well as high-temperature solid lubrication properties, making it suitable for a wide range of applications. Fluorinated graphite holds great promise for application in lithium primary batteries, particularly as a high-energy battery active material. However, the degree of fluorination of fluorinated graphite is closely related to the battery's energy density and electrical conductivity. Researchers have modified fluorinated graphite through methods such as conductive layer coating and material nanosizing to improve battery power characteristics.
