▎ 摘　　要

NOVELTY - Silicon oxide-lithium titanate-based composite negative electrode material comprises graphite, 6-20 %mass additives with respect to the total mass of graphite and additive, conductive agents and binders, where the additives comprise graphene, lithium titanate and silicon oxide. USE - The material is useful for lithium ion batteries. ADVANTAGE - The material has excellent conductivity, feasibility and cyclic performance, and improves comprehensive performance of material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a silicon oxide-lithium titanate-based composite negative electrode material involves mixing graphite and additives, grinding adding the mixture to an organic solvent together with the conductive agent and the binder, stirring completely to obtain a slurry, and coating the slurry on the current collector to obtain the product.
