LOW-COST HIGH-PERFORMANCE SILICON-CARBON (SiC) COMPOSITE ANODE MATERIALS FOR LITHIUM-ION BATTERIES

Abstract

A silicon-carbon (Si/C) composite anode material includes a carbon scaffold material of carbon particles having graphite sheets configured as generally hexagonally shaped cells interconnected to one another in a 3-D honeycomb-like structure of multiple cell arrays and having a plurality of pores separating the cell arrays; silicon embedded in the pores of the 3-D honeycomb-like structure; and a carbon coating on a surface of the carbon particles. A process for producing a silicon-carbon (Si/C) composite anode material includes providing a carbon scaffold material of carbon particles having graphite sheets configured as generally hexagonally shaped cells interconnected to one another in a 3-D honeycomb-like structure of multiple cell arrays having a plurality of pores separating the cell arrays; and depositing silicon into the pores of the 3-D honeycomb-like structure.
