Problems solved by technology
Due to its characteristics, zinc-air batteries have long been favored in the selection of electric vehicle power sources, but they have not been widely promoted. The main reason is that the existing zinc-air battery negative electrode structure and replacement methods cannot meet the requirements. The requirements of power supply for vehicles are not conducive to commercial operation

Abstract
Disclosed is a liquid flow circulation honeycomb type zinc air battery equipped with a capsule-film safety valve. The zinc air battery comprises a battery reaction tank, an air electrode lead wire, and a zinc electrode lead wire, wherein the battery reaction tank is formed by single tubular reaction tanks in an arrangement way; a square upper electrolyte collecting tank and a square lower electrolyte collecting tank connected with each single tubular reaction tank are formed in the upper and lower ends of each single tubular reaction tank respectively; a single columnar zinc electrode is arranged in the tubular centre of each single tubular reaction tank; the bottom of each lower electrolyte collecting tank adopts an inverted pyramid shape; a pyramid-shaped conical filter is arranged at the bottom of a filtering tank; an electrolyte is pumped to each upper electrolyte collecting tank through a reflux pump and a reflux pump return pipe; and a safety valve with a dual-film structure is arranged on a cover plate of the reaction tank. The zinc air battery is high in zinc loading amount in one time, capable of realizing energy supplying as a common internal combustion engine and capable of being started and closed rapidly, and has a dual gradient protection effect due to the safety valve; and by virtue of the characteristics, the zinc air battery can satisfy requirement a vehicle power supply and is safer in use.
Description
Capsule safety valve liquid flow circulation honeycomb zinc-air battery technical field The invention relates to a battery, in particular to a capsule membrane safety valve liquid flow circulation honeycomb zinc-air battery, which belongs to the technical field of battery processing and manufacturing. Background technique A zinc-air battery is a chemical power source that uses oxygen in the air as the positive electrode active material and metal zinc as the negative electrode active material, and undergoes a chemical reaction under the catalysis of an electrocatalyst to generate electrical energy. Since the zinc-air battery uses oxygen in the air outside the battery as the positive electrode active material, the positive electrode active material does not account for the volume and weight of the battery, so this type of battery has high weight-specific energy and volume-specific energy. Zinc-air batteries have attracted extensive attention because of their large capacity, ...
