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.

The application discloses a virtual array-based antenna direction finding method, device and equipment. When performing a direction finding task of a target antenna for the first time, a moving track of the target antenna can be determined according to a direction finding requirement, and a plurality of physical sampling positions can be selected uniformly on the track M The three-dimensional coordinates of the physical sampling positions are recorded. Then the physical sampling positions are equivalent to virtual array antenna elements, and a virtual array antenna is formed according to the track arrangement. A narrowband signal source is received on the virtual array to convert into a complex signal matrix, and a DBF angle estimation is performed on the virtual array antenna based on the complex signal matrix to obtain a preliminary DOA estimation angle, so as to construct adjacent and difference beams based on the estimation angle. The estimation deviation is solved by using the adjacent beams, and the preliminary estimation angle is corrected to obtain a final accurate angle estimation result. The application can improve the DOA estimation precision without increasing the hardware cost and system complexity.
