▎ 摘　　要

NOVELTY - The method involves adding graphene and ethyl orthosilicate in ethanol. The added solution is sprayed by using a spray dryer to obtain a silicon dioxide composite material. The material is soaked in copper acetate solution. The soaked material is filtered and dried for 5 minutes. Graphene/silicon dioxide/silicon/soft carbon laminated composite cathode material is cooled at room temperature. USE - Graphene/silicon dioxide/silicon/soft carbon laminated composite cathode material preparing method. ADVANTAGE - The method enables ensuring high electronic conductivity and effectively improving material electrochemical performance. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating a graphene/silicon dioxide/silicon/soft carbon laminated composite cathode material preparing method.
