Injection type star-shaped inner air electrode zinc-air battery

Abstract

The invention provides an injection type star-shaped inner air electrode zinc-air battery. The injection type star-shaped inner air electrode zinc-air battery comprises a battery material feeding system, a battery reaction tank and a battery waste recovery system, wherein upper and lower ends of the battery reaction tank are shell-shaped openings, the upper opening is connected to a battery material feeding port of the battery material feeding system, the lower opening is connected to a battery waste receiving port of the battery waste recovery system, an air electrode with a star-shaped cross section is arranged in the battery reaction tank along a direction of the upper and lower openings of the battery reaction tank, and colloidal zinc-rich material is arranged around the air electrode. The air electrode is provided with an air-supply system and an air purification system. According to the injection type star-shaped inner air electrode zinc-air battery provided by the invention, the zinc-air battery can perform energy supply like a conventional internal combustion engine due to the unique battery reaction tank structure and the battery material feeding system, and drawbacks of an existing zinc-air battery that a negative electrode structure and a replacement manner thereof cannot meet power supply requirements for a vehicle, and the air electrode is likely to be polluted by dust are avoided.

Description

technical field [0001] The invention relates to a battery, in particular to an injected star-shaped inner air electrode zinc-air battery, which 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...
