All‐Solid‐State Flexible Ultrathin Micro‐Supercapacitors Based on Graphene

Abstract

Flexible, compact, ultrathin and all-solid-state micro-supercapacitors are prepared by coating H₃PO₄/PVA gel electrolyte onto micro-patterned rGO interdigitated electrodes prepared by combining photolithography with selective electrophoretic deposition.
