▎ 摘　　要

NOVELTY - Composite graphite material comprises porous graphite material, asphalt-based carbon material and nano-carbon material, where the asphalt-based carbon material and nano-carbon material are filled in the pores of the porous graphite material and simultaneously coated on the surface of the porous graphite material. USE - The composite graphite material is useful in lithium-ion battery (claimed). ADVANTAGE - The method improves ionic conductivity and electronic conductivity of the composite graphite material, reduces internal resistance and contact resistance, and increases embedding and prolapse rate of lithium-ions. The composite graphite anode material exhibits good first Coulomb efficiency, cycle performance and magnification performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of composite graphite material.
