Zinc air battery with tube-injected internal air electrode

Abstract

The invention discloses a zinc air battery with a tube-injected internal air electrode. The zinc air battery comprises a battery feeding system, a battery reaction tank and a battery waste recovery system, and is characterized in that the battery reaction tank is a tubular body with open ports at the head and tail ends; the head port of the tubular body is connected with a battery raw material feeding port of the battery feeding system; the tail port of the tubular body is connected with a battery waste receiving port of the battery waste recovery system; a tubular air electrode is arranged in an axial direction of the battery reaction tank in the tubular body of the battery reaction tank; the outside of a tubular body of the air electrode is full of a colloidal-state zinc-rich substance; an air electrode internal ventilating tube is arranged in the air electrode; and the air electrode is provided with an air supply system and an air purification system. The zinc air battery adopts a unique battery reaction tank structure and the battery feeding system, so that the zinc air battery can realize energy supply the same as a common internal combustion engine, and avoids the disadvantages that a cathode structure and a replacement mode of the existing zinc air battery cannot meet a vehicular power source requirement and the air electrode is easily polluted by dust.

Description

technical field [0001] The invention relates to a battery, in particular to a pipeline-injected 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 and...
