▎ 摘　　要

NOVELTY - A structured supercapacitor is a sandwich laminated structure comprising a structured electrode and a structured electrolyte. The structured electrode is made of graphene. The structured electrolyte is a hydration product of a polymer-inorganic ion aqueous solution and cement. The content of polymer is 1-20 % with respect to the content of cement. USE - Structured supercapacitor. ADVANTAGE - The structured supercapacitor has excellent electrical performance and mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the structured supercapacitor.
