▎ 摘　　要

NOVELTY - A graphene/activated carbon composite film preparation method involves mixing acid treated activated carbon with graphene oxide dispersion liquid to obtain graphene/activated carbon mixture. The graphene/activated carbon mixture is frozen to obtain solid mixture. The solid mixture is dried and subjected to thermal reduction of graphene oxide to obtain a graphene/activated carbon aerogel. The aerogel is mechanically pressed by roll press or tablet press to obtain graphene/activated carbon composite film. USE - Method for preparing graphene/activated carbon composite film that is utilized in super capacitor electrode (claimed). ADVANTAGE - The method enables preparing the graphene/activated carbon composite film with self-supporting properties and better bending property. The super capacitor electrode can be prepared with high specific capacity and stable cycle characteristics and without addition of bonding agent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a super capacitor electrode.
