▎ 摘　　要

NOVELTY - A fluorinated graphene-lithium vanadium fluorophosphate composite material preparation method involves mixing graphene with vanadium pentoxide, fluoride salt, phosphate and lithium salt to obtain a mixture. The mixture is calcined in an oxygen free environment. The calcined mixture is cooled to obtain finished product. USE - Method for preparing fluorinated graphene-lithium vanadium fluorophosphate composite material for preparing lithium ion battery, cathode material and capacitor (claimed). ADVANTAGE - The method enables preparing fluorinated graphene-lithium vanadium fluorophosphate composite material with high power density, high conductivity and stable structural performance in a simple, inexpensive and eco-friendly manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a fluorinated graphite alkene-lithium vanadium fluorophosphate composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for preparing fluorinated graphene-lithium vanadium fluorophosphate composite material.'(Drawing includes non-English language text)'
