▎ 摘　　要

NOVELTY - Graphite negative electrode material has a pomegranate-like structure, comprises a graphene shell layer and various graphite monomer particles wrapped in the graphene shell layer. The graphite monomer particles include graphite particles and an amorphous carbon layer wrapped on the outer surface of the graphite particles. USE - Graphite cathode material used in lithium ion battery (Claimed). ADVANTAGE - The cathode material shortens the transmission path of the ion, improves the fast charging and discharging performance of the lithium ion battery, improves the cycle stability, charging and discharging efficiency and safety performance of the lithium ion battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of graphite anode material, which involves dispersing graphite, carbon source and graphene in water, grinding treatment to obtain a grinding product, then spraying and granulating the ground product to obtain a graphite negative electrode precursor, and heat-treating the graphite negative electrode precursor in a protective gas atmosphere at a temperature of 500-1500 degrees C for 2-48 hours to obtain a graphite negative electrode material with a pomegranate-like structure.
