▎ 摘 要
NOVELTY - The material comprises active carbon particles, graphite, bonding agent and 2-7 graphene-containing layers, where the bonding agent is polyvinylidene fluoride, polyvinyl alcohol or sodium carboxymethyl cellulose. Mass ratio of graphene and active carbon particles is 1:9. USE - Super-capacitor electrode material. ADVANTAGE - The material increases contact area of the graphene and the active carbon particles so as to improve electron transport rate. The material enables adjusting contact gap between the active carbon particles for ensuring electrolyte ion storage and realizing continuous supply of ions, thus increasing power density, energy density, power performance and circulation stability of a super-capacitor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a super-capacitor electrode material preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a super-capacitor electrode material.
