▎ 摘　　要

NOVELTY - A composite cathode comprises a catalytic layer, a carbon cloth layer, a carbon-based layer, and a diffusion layer arranged from one side to other side. The catalytic layer comprises graphene oxide/magnesium oxide composite material, activated carbon, and perfluorosulfonic acid. USE - Composite cathode used in microbial fuel cell, lithium battery, or ultra-capacitor (claimed). ADVANTAGE - The composite cathode is economical, has large surface area, high conductivity, and stable electron transfer efficiency, and is operated smoothly with high output power. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite cathode.
