▎ 摘　　要

NOVELTY - Preparing three-dimensional graphene, comprises mixing oxygen-containing organic polymer with copper salt, calcining at 400-800 degrees C under inert atmosphere, then washing the calcined product with ferric chloride solution, and drying to obtain final product. USE - The three-dimensional graphene is useful as electrode material for sodium ion battery (claimed). ADVANTAGE - The method: has simple operation, short reaction period, and high product yield; is suitable for industrial production; and produces three-dimensional graphene material having excellent electrochemical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use of three-dimensional graphene as electrode material for sodium ion battery.
