▎ 摘　　要

NOVELTY - Preparing cobalt fluoride-based composite electrode material involves using cobalt-based metal organic framework is used as precursor and combining with fluorine-containing material to obtain cobalt fluoride, grinding fully graphene oxide and cobalt fluoride with specific preset ratio, placing in a tube furnace, the gas atmosphere is air, heating up to 300-500 degrees C at a heating rate of 5-10 degrees C/minutes, keeping warming for a preset time, taking out the powder after cooling, and grinding fully to obtain the composite electrode material of reduced graphene oxide-cobalt fluoride. USE - Method for preparing cobalt fluoride-based composite electrode material. ADVANTAGE - The method enables to prepare the cobalt fluoride-based composite electrode material with better electrochemical performance, layered shape of reduced graphene oxide and better conductivity.
