▎ 摘　　要

NOVELTY - A graphene-based lithium ion battery anode material is a three-dimensional porous graphene-non-carbon material composite electrode material which comprises a three-dimensional porous graphene and a non-carbon material loaded on the three-dimensional porous graphene. The anode material has a rich pore structure, specific surface area of 170-400 m2/g, pore volume of 0.18-1.2 cm3/g, and bulk density of 0.6-3.0 g/cm3. The sum of the volumes of the pores in the anode material is 1.9-4 times the sum of the volumes of the non-carbon materials. USE - Graphene-based lithium ion battery anode material (claimed). ADVANTAGE - The graphene-based lithium ion battery anode material is prepared by simple process at low cost with high ion transport and electronic conductivity, electrochemical lithium storage capacity, and cycle performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-based lithium ion battery anode material.
