1results about How to "Good cycle reversibility" patented technology

This invention discloses a hydrogen-assisted rechargeable battery method for hydrogen storage and production, belonging to the field of hydrogen energy storage and electrochemical energy storage technology. The method includes four core steps: battery assembly, circulating electrolyte supply, charging for hydrogen storage, and discharging for hydrogen production. During charging, hydrogen-containing gas is introduced into the cathode, where a hydroxide reaction occurs, and metal ion reduction and deposition occur at the anode, storing hydrogen energy as a metallic element in a solid state under normal pressure. During discharging, a metal oxidation and dissolution reaction occurs at the anode, and a hydrogen evolution reaction occurs at the cathode, generating hydrogen gas in situ and releasing hydrogen energy on demand. This invention eliminates the oxygen evolution reaction of traditional water electrolysis, using hydroxide coupled with metal oxidation-reduction to achieve hydrogen energy storage and release. It offers high storage safety, low reaction overpotential, high energy efficiency, and good cycle reversibility, solving the problems of poor safety, high energy consumption, and low energy efficiency in existing hydrogen storage technologies. It can be widely applied to renewable energy hydrogen production, large-scale hydrogen energy storage, and distributed hydrogen energy supply scenarios.
