▎ 摘　　要

NOVELTY - The method involves loading porous silicon dioxide on a graphene surface and forming graphene silica. Manganese salt, lithium salt, additive and graphene silica are evenly mixed to obtain a solution. Organic acid or organic amine is added to the resulting solution. The resulting solution is heated to obtain volatile solid, and the solid is heated under protection of inert atmosphere to obtain an intermediate. The intermediate is ground and pressed under inert atmosphere and calcined to obtain graphene silicon acid manganese lithium material. USE - Method for preparing graphene silicon acid manganese lithium anode material for lithium ion battery. ADVANTAGE - The preparation of graphene silicon acid manganese lithium anode material is made simple. The conductivity of graphene silicon acid manganese lithium anode material is effectively increased.
