Cylindrical liquid flow circulating honeycomb type zinc air battery

Abstract

A cylindrical liquid flow circulation honeycomb zinc-air battery, including a battery reaction tank, air electrode lead-out wires, and zinc electrode lead-out wires. The battery reaction tank is formed by arranging and combining tubular reaction tank monomers. The ends are respectively provided with cylindrical upper and lower sumps connected with the tubular reaction tank monomer, the center of the tube body of the tubular reaction tank monomer is provided with a columnar zinc electrode unit, and the bottom of the lower sump is Inverted conical shape, a conical conical filter is set at the bottom of the filter tank, the electrolyte is pumped into the upper liquid collection tank through the reflux pump and the reflux pump return pipe, and a double-membrane structure is installed on the cover of the reaction tank. valve. The present invention has a large amount of zinc loaded at one time, can realize energy supply like an ordinary internal combustion engine, the battery can be quickly opened and closed, and the safety valve has double gradient protection. The above-mentioned characteristics enable the zinc-air battery to meet the requirements of the vehicle power supply, and it is safer to use.

Description

Cylindrical flow circulating honeycomb zinc-air battery technical field The invention relates to a battery, in particular to a cylindrical liquid flow circulating 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 active material and metal zinc as the negative active material, and generates electrical energy by chemical reaction under the catalysis of electrocatalysts. Since the zinc-air battery uses the oxygen in the air outside the battery as the positive electrode active material, the positive electrode active material does not occupy the volume and weight of the battery, so the battery has high specific energy by weight and volume. Zinc-air batteries have received extensive attention due to their large capacity, high specific energy, stable comprehensive performance, safe use, readily available and inexpen...

AI Technical Summary

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
