NOVELTY - Preparing lithium ion battery bamboo charcoal anode material, comprises (i) adding bamboo charcoal and graphene into the aqueous solution of metal nitrate, mixing uniformly and then heating, drying to obtain precursor A, where the mass ratio of bamboo charcoal, anf graphene is 90-95:1-6; (ii) calcining the precursor A under an inert atmosphere, to obtain precursor B; and (iii) adding the precursor B into the concentrated nitric acid in constant stirring, filtering, washing, and drying. USE - The lithium ion battery bamboo charcoal anode material is useful for the preparation of a lithium ion battery (claimed). ADVANTAGE - The charcoal anode material has wide source and low price, strong operability, and good chemical property of modified bamboo charcoal.
