Abstract
The invention discloses an industrial synthesis method of petroleum coke fluoride. Fluorine gas or the mixture of fluorine gas and inert gas is led into a certain reaction container at certain flow speed and pressure for reaction; and then petroleum coke fluoride of various specifications and with the fluorine content of more than 58 percent is obtained at certain temperature. Compared with method specified in other relevant patents, the method has simple operation and can fulfill industrial scale. The petroleum coke fluoride products obtained are mainly applied to the electrode materials of a novel high energy lithium ion battery.
