▎ 摘　　要

NOVELTY - Polyaniline/graphene composite electrode material, prepared by orderly and quantitative solution mixing between graphene, oxidizing agent and aniline monomer and dilute sulfuric acid respectively, performing high-energy ball milling with fixed time and speed, filtering, washing and vacuum drying. The solution contact resistance and charge transfer resistance of the composite electrode material are very small, the charge transfer ability is excellent, and has the advantages of high specific capacitance and high cycle stability. USE - Polyaniline/graphene composite electrode material. ADVANTAGE - The polyaniline/graphene composite electrode material has small resistance and charge transfer resistance, excellent charge transfer ability, high specific capacitance and high cycle stability. The method is simple and efficient, environment-friendly, and easy to obtain raw material. The obtained composite material realizes the uniform accumulation of poly aniline on the surface of the graphene, and has excellent cycle stability in the charging and discharging process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing polyaniline/graphene composite electrode material.
