▎ 摘  要

NOVELTY - Preparing electrode using graphene oxide as conductive additive comprises using the graphene as the conductive additive to prepare the uniform mixing material of oxidation graphene, electrode material and conductive carbon, processing microwave radiation to rapidly reduce graphene oxide in situ, preparing reduction oxidation graphene electrode material, uniform mixed material of conductive carbon, using reduction oxidation graphene electrode material, uniform mixed material of conductive carbon to prepare electrode by matching with the agglomerant. The method further comprises placing the electrode pole piece in the electric double-roller machine for multiple times of rolling and pressing, and cutting into electrode and packaging to prepare the super-capacitor. The agglomerant includes polyvinylidene fluoride, styrene-butadiene rubber and carboxymethyl cellulose, and the solvent includes N-methylpyrrolidone, deionized water and N,N-dimethylformamide. USE - The electrode is used as super capacitor electrode, and in electrochemical energy storage electrode preparation field. ADVANTAGE - The method: uses the oxidation graphene directly as the conductive additive to improve the graphene and the electrode material, ensures uniform dispersion between the conductive carbon, and avoids the introduction of the dispersant.
