▎ 摘　　要

NOVELTY - A flexible positive electrode comprises composite film formed by a film-forming substrate, and electrode materials uniformly dispersed in the film-forming substrate. The film-forming substrate is carbon nanotubes. The electrode material is Vat Brown 1/graphene oxide composite material. The Vat Brown 1/graphene oxide composite material is prepared from raw material Vat Brown 1 and graphene oxide through hydrothermal reaction or a solvothermal reaction. USE - Flexible positive electrode. ADVANTAGE - The flexible positive electrode has a large number of large conjugate structures, which is beneficial to improve the conductivity of the electrode material. The flexible positive electrode has excellent deformability, energy density and conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the flexible positive electrode.
