A honeycomb type zinc-air cell

Abstract

A honeycomb zinc-air battery, including a battery reaction tank, an air electrode lead-out wire, and a zinc electrode lead-out wire, characterized in that the battery reaction tank is formed by arranging and combining tubular reaction tank monomers, and there are gaps between the tubular reaction tank monomers Air gap, the upper and lower ends of the tubular reaction tank monomer are respectively provided with an upper liquid collection tank and a lower liquid collection tank connected with the tubular reaction tank monomer; the tubular reaction tank monomer is a tubular body surrounded by air electrodes , the upper end of which is connected to the bottom plate of the upper liquid collection tank, and the lower end is connected to the top plate of the lower liquid collection tank. The center of the tube body of the tubular reaction tank monomer is provided with a columnar zinc electrode unit, and the upper end of the columnar zinc electrode unit is connected to the zinc The electrodes are connected through the bridge to form a zinc electrode group; the outer side of the battery reaction tank is provided with an air electrode guard plate with air holes. The invention uses a unique structure of the air electrode and the zinc electrode, so that the battery capacity is large, and the replacement of the zinc electrode is convenient and fast, so that the zinc-air battery can meet the requirements of the vehicle power supply.

Description

technical field [0001] The invention relates to a battery, in particular to a honeycomb zinc-air battery, and belongs to the technical field of battery processing and manufacturing. Background technique [0002] 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 performance, safe use, easy-to-obtain and low-cost materials, and envir...

Problems solved by technology

[0003] 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
