▎ 摘　　要

NOVELTY - Aqueous carbon-hydrogen secondary battery comprises electrolyte, aqueous solution containing soluble ion, anode which is carbon-based electrode material for realizing reversible adsorption and desorption of the soluble ion, cathode which is used for hydrogen evolution reaction out of the hydrogen oxidation reaction with the electrolyte interface, and a diaphragm set between the anode and the cathode. The electrolyte is acidic, neutral or alkaline. The soluble ions include soluble cations and soluble anions, and the ion concentrations of the soluble cations and soluble anions are 0.01-30 mol/l, respectively. USE - Used as aqueous carbon-hydrogen secondary battery. ADVANTAGE - The battery has excellent cycle life and fast charging and discharging ability. The battery can work under environment of different high and low temperature and full pH range.
