Abstract

Abstract : All‐solid‐state, flexible, symmetric, and asymmetric microsupercapacitors are fabricated by a simple method in a scalable fashion from laser‐induced graphene on commercial polyimide films, followed by electrodeposition of pseudocapacitive materials on the interdigitated in‐plane architectures. These microsupercapacitors demonstrate comparable energy density to commercial lithium thin‐film batteries, yet exhibit more than two orders of magnitude higher power density with good mechanical flexibility.
