▎ 摘　　要

NOVELTY - Preparing a silicon carbon two-dimensional layered composite electrode material involves subjecting the graphene/silicon composite aerogel to high pressure treatment to obtain sheet-like graphene/silicon composite gel; calcining the sheet graphene/silicon composite gel to obtain the silicon carbon two-dimensional layered composite electrode material; where the pressure of the high-pressure treatment is 20-60 MPa. USE - Method for preparing a silicon carbon two-dimensional layered composite electrode material, which is used in the negative electrode material of lithium-ion battery. ADVANTAGE - The method is good for improving the graphene contact and the silicon, improving the tap density of the material and the corresponding volume energy density, which is an excellent lithium-ion battery negative electrode material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of the silicon carbon two-dimensional layered composite electrode material used in the negative electrode material of lithium-ion battery.
