▎ 摘  要

NOVELTY - Preparation of high conductive and high stability flexible graphene film electrode comprises mixing graphene oxide and ultra-pure water to obtain graphene oxide suspension, stirring, and oxidizing to obtain graphene oxide gel; uniformly coating on surface of polyethylene terephthalate film and drying; peeling graphene oxide film, putting in a high temperature furnace under the protection of argon gas to reduce at high temperature and cooling; mechanically flattening the graphene film; using laser carving machine to carve the graphene film; and fixedly connecting one end of the graved graphene film with a copper foil. USE - The method is used for preparing high conductive and high stability flexible graphene film electrode in battery, electrochemical sensor and electrocatalysis fields (claimed). ADVANTAGE - The graphene film electrode has good stability and conductivity and is suitable for various electrochemical operation environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for flexible graphene film electrode.
