Diaphragm safety valve cellular zinc air battery

Abstract

The invention discloses a diaphragm safety valve cellular zinc air battery which comprises a battery reaction tank, an air electrode outgoing line and a zinc electrode outgoing line, and is characterized in that the battery reaction tank is formed by performing permutation and combination on tubular reaction tank cells, wherein an upper liquid collection tank and a lower liquid collection tank which are mutually communicated with the tubular reaction tank cells are respectively arranged at the upper and lower ends of the tubular reaction tank cells; a liquid storage tank is arranged at the lower end of the lower liquid collection tank; a drain pipe is arranged at the tank bottom of the lower liquid collection tank; an electrically controlled drain valve is arranged at the orifice of the drain pipe; an electrolytic reflux pump liquid inlet is formed in one side of the bottom end of the liquid storage tank; a reflux pump liquid outlet is formed in one side of the upper liquid collection tank; a zinc electrode assembly and a battery cover plate are made into a whole; and a double-diaphragm safety valve is arranged on the battery cover plate. According to the zinc air battery disclosed by the invention, due to the unique air electrode and zinc electrode structure, the battery capacity is high, the zinc electrode is conveniently and rapidly replaced, the battery can be rapidly turned on or off, and the battery is safe to use, so that the zinc air battery can meet the requirement on vehicle power.

Description

Capsule safety valve honeycomb zinc-air battery technical field The invention relates to a battery, in particular to a honeycomb zinc-air battery with a membrane safety valve, and 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, high specific energy, stable comprehensive performa...

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
