Silicon-carbon-graphene composite and manufacturing method thereof, and lithium ion secondary battery using the same

Abstract

The present disclosure provides a method for manufacturing a silicon-carbon-graphene composite comprising, preparing a suspension in which silicon, carbon source and graphene oxide are dispersed, subjecting the suspension to an aerosol process to form a silicon-carbon source-graphene oxide composite and heat-treating the silicon-carbon source-graphene oxide composite to form a silicon-carbon-graphene composite, and prevents direct contact of the electrolyte, so it can exhibit excellent cycling performance and stability.
