- - Porous Silicon-Nano Carbon-Multilayer Graphene Composite Using Multi-Layer Graphene and Metal Alloy Powder and Manufacturing Thereof

摘要

The present invention provides a porous silicon-nano carbon layer comprising a shell including a carbon layer and graphene in a porous silicon core particle having a micro-sized one pore and a nano-sized second pore by chemically etching a metal alloy powder. It provides a multi-layer graphene composite and a method of manufacturing the same. The present invention is a porous silicon-nano carbon layer-graphene composite having a core-shell structure wrapped with a graphene shell on a carbon-coated porous silicon particle, wherein the porous silicon has a first pore and a different size Comprising two pores, the coated carbon has a thickness of 1 ~ 10nm, the graphene shell provides a porous silicon-nano carbon layer-graphene composite having a thickness of less than 20nm.
