▎ 摘　　要

NOVELTY - The material has a lithium-rich anode material having the inside and outside surfaces that are covered by the aluminum oxide and graphene layers. The aluminum oxide layer accounts for lithium ion battery having positive pole material with the mass percentage content of 1-5%. The graphene accounts for lithium ion battery positive pole material having a mass percentage content of about 1-15%. USE - Lithium ion battery anode material. ADVANTAGE - The circulation property is improved under the high voltage condition and time performance. The irreversible capacity loss amount is reduced. The electrochemical performance is good. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing lithium ion battery anode material. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation of circulation performance of lithium ion cell positive pole material. (Drawing includes non-English language text)
