NOVELTY - Preparing metal oxide chloride doped graphene lithium ion battery anode material involves uniformly dispersing graphene oxide in organic solvent to obtain slurry, dissolving metal source in organic solvent and slowly adding into slurry, and stirring for 10 hours at room temperature to obtain gel. The gel is uniformly coated on copper foil, dried, cut, placed into tube furnace, and then calcined under protection of inert gas to obtain metal oxide chlorine-doped graphene composite material. USE - Method for preparing metal oxide chloride doped graphene lithium ion battery anode material. ADVANTAGE - The method enables to prepare metal oxide chloride doped graphene lithium ion battery anode material that improves the cycle stability of the cathode material and discharge capacity i.e. 600 milliampere hour/g.
