Metal-air battery capable of discharging for multiple times and implementation method

Abstract

The invention provides a metal-air battery capable of discharging for multiple times. The battery comprises a shell, a metal electrode, an air electrode, an electrolyte tank and a cleaning liquid tank. The shell is provided with a cavity, a liquid inlet and a liquid outlet, the metal electrode and the air electrode are located in the cavity, the electrolyte tank is filled with an electrolyte, thecleaning liquid tank is filled with a cleaning liquid, and the cleaning liquid contains a corrosion inhibitor. An outlet of the electrolyte tank is communicated with the liquid inlet, an inlet of theelectrolyte tank is communicated with the liquid outlet, an outlet of the cleaning liquid tank is communicated with the liquid inlet, an inlet of the cleaning liquid tank is communicated with the liquid outlet, and the electrolyte tank and the cleaning liquid tank are operated to selectively convey electrolyte or cleaning liquid into the cavity. According to the metal-air battery, the problem of difficulty in secondary starting of the metal-air battery can be solved, and self-corrosion or corrosion of the metal electrode in the shelving process is avoided, so that intermittent discharge, repeated use and repeated discharge of the metal-air battery can be realized. The invention further provides an implementation method for multiple times of discharging of the metal-air battery.

Description

technical field [0001] The invention relates to the technical field of preparation of metal-air batteries, in particular to a metal-air battery capable of multiple discharges and a realization method. Background technique [0002] With the increasingly serious energy and environmental problems, human beings urgently need to develop new energy sources to replace traditional fuels. Metal-air batteries have been extensively studied due to their advantages of high specific energy, low cost, and environmental protection. Among them, metal zinc is rich in resources, low in price, and has a stable reaction process. In recent years, researchers have been conducting research on zinc-air batteries. [0003] Although scholars at home and abroad have continuously improved the performance of metal-air batteries by studying catalyst materials in recent years, due to the continuous self-corrosion reaction of the metal electrodes during the storage process after the reaction, a dense passi...
