▎ 摘　　要

NOVELTY - A composite cathode material comprises 27-73 %mass ruthenium oxide hydrate, 16-49 %mass highly-hydrophilic multiwalled carbon nanotubes, 5-15 %mass graphene oxide, 1-10 %mass electroconductive agent and 3-8 %mass binder. USE - Composite cathode material is used for tantalum-based ruthenium oxide-nano-carbon composite electrode (claimed). ADVANTAGE - The composite cathode material improves capacity and power density of the tantalum electrode. The highly-hydrophilic multiwalled carbon nanotubes improve specific surface area and hydrophilicity of the cathode material.
