Abstract

The invention discloses a novel rechargeable zinc air battery, and belongs to the field of metal air batteries. The novel rechargeable zinc air batterycomprises a battery body, which is composed of a battery shell, an air electrode, a zinc sheet electrode and a diaphragm, wherein the air electrode, the zinc sheet electrode and the diaphragm are fixed in the battery shell in a sandwich intercalation manner, the battery shell comprises a battery lower shell and a battery upper shell, and a zinc sheet fixing groove matched with the lower side of the zinc sheet electrode is formed in the inner side of the battery lower shell. According to the invention, the air electrode, the zinc sheet electrode and the diaphragm are fixed in the battery shell in a sandwich intercalation manner, so that the service efficiency of the battery is improved, and the structure of the rechargeable zinc-air battery is optimized; a liquid injection hole and a liquid discharge hole are formed in the outer side surface of the battery shell, so that the electrolytic solution can be replaced in time, and the use performance of the battery is ensured; and the large air inlet channel area of the fixed air inlet partition plate can keep air circulating in the battery, and has the effects of ventilation, heat dissipation, water prevention and protection.

Description

technical field [0001] The invention relates to the technical field of metal-air batteries, in particular to a novel rechargeable zinc-air battery. Background technique [0002] Zinc-air battery is a kind of metal-air battery, which is also a new energy battery. It has the advantages of low cost, high safety, no pollution, high specific capacity, etc., and its working voltage is stable, with flexible adaptability and designability , the positive active material of this new type of rechargeable zinc-air battery comes from oxygen in the air, while the negative active material is metal zinc, and the electrolyte is aqueous potassium hydroxide solution, which undergoes an electrochemical reaction under the action of a rechargeable catalyst. A chemical power source that produces electrical energy. [0003] Due to the advantages of high safety and high specific capacity, zinc-air batteries can be used in the field of power batteries, but they have not been widely used. The main r...
