▎ 摘　　要

NOVELTY - The structure has a core fixed with an anode active material of a lithium ion battery and a lithium cobaltite, lithium manganite and nickel lithium manganate or composite material. A carbon layer is fixed with a graphene sheet in a shell. The graphene sheet is coated with methyl blue by carrying out hydrophilic modification of the graphene. Mixed solution is sealed in a hydrothermal reaction kettle at 180 degrees centigrade for 12-50h. Graphite oxide is dispersed by ultrasonic in the solvent. USE - Lithium ion battery anode material integrated core-shell structure. ADVANTAGE - The structure has simple process and low production cost, and can effectively improve power charge-discharge performance of the lithium ion battery in a high temperature environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium ion battery anode material preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a photograph view of a lithium ion battery anode material integrated core-shell structure.
