▎ 摘　　要

NOVELTY - An electrode material comprises MXene material and graphene material. USE - Electrode material is used for supercapacitor (claimed). ADVANTAGE - The high-performance electrode material has excellent flexibility by containing graphene, conductivity, and electrochemical performance, with reduced volume change of MXene material during charging and discharging. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the electrode material, which involves dissolving predetermined amount of graphene material and MXene material in solvent to obtain mixed solution, and subjecting to hydrothermal reaction at 150-280 degrees C.
