▎ 摘  要

NOVELTY - Graphite oxide powder is dispersed into deionized water to obtain dispersion liquid. Solid-liquid separation is performed by contacting dispersion liquid with acid, and obtained solid precipitate is dried to obtain acid precipitated graphite oxide powder. The obtained powder is subjected to heat treatment for 1-60 seconds at 600-1200 degrees C in presence of inert gas to obtain graphene electrode active material. USE - Manufacture of graphene electrode active material for electrode material for super capacitor electrode plate (all claimed). ADVANTAGE - The method efficiently provides graphene electrode active material having low equivalent series resistance, high specific capacitance, and excellent cycling performance, by simple method. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) super-capacitor electrode material, which contains bonding agent and graphene electrode active material; and (2) super capacitor electrode plate.
