Problems solved by technology

In general laboratories, the synthetic fluorine content can reach more than 55%, but the output of fluorinated graphite is very low, and it can only be prepared on a small scale.
Under the premise of increasing the production capacity of general industrial synthesis methods, it is difficult to increase the fluorine content, so the quality of fluorinated graphite is not good, and the production is easy to explode

example 1

[0008] Add 500 microns and 600 kg of graphite into the reaction vessel, spread evenly on the reaction plates of each layer, heat the reactor to a temperature of 200 to 300 degrees, vacuumize the reaction system, and remove the air from the reaction system. Raise the temperature to 500 to 600 degrees, slowly introduce fluorine gas, control the flow rate of fluorine gas added by the fluorine gas flow meter to 3 to 50 liters per minute, continue to react at this flow rate for 5 to 10 hours, stop heating, let the reaction The kettle is naturally cooled to a temperature below 300 degrees, and nitrogen gas is introduced into the cooled reaction vessel to drive away the residual fluorine gas in the reaction vessel, and the reaction ends. Open the reaction kettle, take out the solid powder in the reaction kettle according to the color classification, and obtain the product. The total weight of the product is 1500 kg, the black color is 300 kg, the fluorine content is 50% to 55%, and th...

Abstract

The invention discloses an industrial synthesis method for graphite fluoride. Fluorine gas or the mixture of fluorine gas and inert gas is led into a specific reaction container filled with graphite at certain flow speed and pressure; and then graphite fluoride with various specifications of more than 50 percent is obtained by controlling reaction temperature, reaction pressure and reaction speed. Compared with methods specified in other relevant patents, the method has simple operation and can carry out industrial production safely. The obtained graphite fluoride products are mainly applied to the electrode materials of novel high-energy lithium ion battery and solid lubricant material.

Description

technical field [0001] Graphite fluoride is a solid lubricant with excellent lubricating properties, widely used in national defense, machinery, precision instruments and other fields. Background technique [0002] There are many ways to synthesize graphite fluoride, and there are relevant patent reports at home and abroad. The synthesis of graphite fluoride by different methods has its own characteristics. Generally, the synthetic fluorine content in the laboratory can reach more than 55%, but the output of fluorinated graphite is very low, and it can only be prepared on a small scale. Under the premise of increasing the production capacity of general industrial synthesis methods, it is difficult to increase the fluorine content, so the quality of fluorinated graphite is not good, and the production is easy to explode. Contents of the invention [0003] The invention provides an industrial synthesis method of fluorinated graphite, which can produce fluorinated graphite ...
