▎ 摘　　要

NOVELTY - Preparing flexible electrodes of dense structure reduced graphene oxide (rGO)/MXene-sulfuric acid super capacitors involves mixing graphene oxide aqueous dispersion and MXene aqueous dispersion first, adding sulfuric acid, and mixing uniformly. The metal zinc flake is infiltrated into the mixed solution and let it stand. The reduced graphene oxide (rGO)/MXene-sulfuric acid composite film is obtained on the surface of the metal zinc sheet, and after peeling to obtain reduced graphene oxide (rGO)/MXene-sulfuric acid composite film super capacitor flexible electrode. USE - Method for preparing flexible electrodes of dense structure reduced graphene oxide (rGO)/MXene-sulfuric acid super capacitors. ADVANTAGE - The method enables to prepare flexible electrodes of dense structure reduced graphene oxide (rGO)/MXene-sulfuric acid super capacitors which has simple to prepare, and has strong designability, wide applicability, good electrochemical performance and have broad application prospects in the field of electrochemical materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using flexible electrode with dense structure RGO/MXene-sulfuric acid supercapacitor, which involves drying and cutting RGO/MXene-H2SO4 composite membrane to obtain a flexible electrode;#using filter paper soaked in sulfuric acid as a separator, and separating two identical flexible electrode sheets by a separator, and finally bonding together to assemble a super capacitor.
