NOVELTY - Preparation of anode material involves mixing appropriate amount of 2,2-bis(4-(4-aminophenoxy)phenyl)hexafluoropropane, 3,3',4,4'-biphenyltetracarboxylic dianhydride and graphene oxide to obtain a polyamic acid/graphene oxide, adding acetic anhydride and triethylamine to obtain a concentrate, performing high-temperature firing to obtain a composite, adding appropriate amount of N-methylpyrrolidone, pyralene, polyvinylidene fluoride, nanosilicon particles, carbon nanotubes and beta-cyclodextrin to obtain a conductive paste, drying, cooling, and slicing using a manual microtome. USE - Preparation of material used for forming anode for lithium-ion battery used for energy electric vehicles and consumer electronics. ADVANTAGE - The method enables preparation of economical and environmentally-friendly anode material having stable chemical performance and electrochemical performance. The anode formed using the material retains an intact structure, and stable cycle performance during charging/discharging process, and provides lithium-ion battery having improved battery capacity and safety. The lithium ions in the material have desired diffusion property and high electroconductivity.
