▎ 摘　　要

NOVELTY - Self-supporting high-specific capacitance tungsten carbide-reduced graphene oxide-manganese oxide electrode is prepared by in-situ growth of the active material manganese oxide on the tungsten carbide-reduced graphene oxide conductive substrate. The electrode still retains the three-dimensional hierarchical porous network structure of the original wood, and is a self-supporting electrode without adding any bonding agent and conductive agent. USE - The self-supporting high-specific capacitance tungsten carbide-reduced graphene oxide-manganese oxide electrode for use in solar power generation, wind power generation and military equipment. ADVANTAGE - The method provides a self-supporting high specific capacitance tungsten carbide-reduced graphene oxide-manganese oxide electrode without any bonding agent and conductive agent. The reduced graphene oxide which grows in the original position directly improves the multiplying power performance of the electrode. The electrode shows excellent capacitance performance by the manganese oxide generated by the hydrothermal method, and the perfect compound of the ternary material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a method for preparing the self-supporting high specific capacitance tungsten carbide-reduced graphene oxide-manganese oxide electrode; a self-supporting activated wood carbon electrode; a method for preparing a self-supporting activated wood carbon electrode; and a tungsten carbide-reduced graphene oxide-manganese oxide/activated wood carbon supercapacitor.
