  "textContent": "The present invention discloses a pre-lithiated silicon-carbon multilayer composite negative electrode material for lithium ion batteries and a preparation method thereof. The composite negative electrode material includes an amorphous carbon matrix, pre-lithiated silicon monoxide particles and graphene materials; the graphene materials are uniformly coated on the outer surface of the pre-lithiated silicon monoxide to form composite particles; and the composite particles are uniformly dispersed in the amorphous carbon matrix. According to the present invention, the silicon monoxide particles are pre-lithiated to greatly improve the initial coulombic efficiency (ICE) of the silicon-based negative electrode material; the graphene materials greatly improve the mechanical performance and conductivity of the composite materials due to the light weight, high strength and excellent conductivity thereof.",
