▎ 摘　　要

NOVELTY - The material comprising a silicone composite material negative electrode, where the silicone composite material negative electrode includes composite of silicon dioxide and metal oxide, nano silicon and carbon material and composite of silicon dioxide and metal oxide and mass ratio of nano silicon and the carbon material is calculated about 5-9: 0.5- 5: 0.1-1.6 and carbon material comprises carbon nano tube, graphene and acetylene black. USE - Silicone composite negative electrode material for used in a lithium ion battery (claimed). ADVANTAGE - The silicon-oxygen composite negative electrode material reduces volume expansion problem of the material in the charging and discharging process, and improves the circulation stability of material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: A silicone composite material negative electrode; A method for preparing silicon-oxygen composite negative electrode material; and A negative electrode. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of a silicone composite negative electrode material for used in a lithium ion battery.
