▎ 摘　　要

NOVELTY - The method involves dispersing graphene in ethanol. Graphene slurry is formed on a ball milling medium, where ball milling time is maintained about 24 to 48 hours. A vacuum oven is connected with the ball milling medium. USE - Lithium mangante oxide (LiMn2O4) lithium ion battery anode material graphene modified preparation method for industrial field. ADVANTAGE - The method enables ensuring simple operation, better lithium ion battery circulation property and better conductivity and charge transfer speed in an inexpensive manner. DESCRIPTION OF DRAWING(S) - The drawing shows a graph view illustrating a lithium mangante oxide lithium ion battery anode material graphene modified preparation method.
