Injection type inner air electrode zinc air battery

Abstract

Disclosed is an injection type inner air electrode zinc air battery. The injection type inner air electrode zinc air battery comprises a battery material supplying system, a battery reaction tank and a battery waste material recycling system; the injection type inner air electrode zinc air battery is characterized in that opening shell-shaped bodies are arranged on the upper and lower ends of the battery reaction tank; the upper opening is connected with battery raw material supplying openings of the battery material supplying system while the lower opening is connected with battery waste liquid receiving openings of the battery waste material recycling system; an air electrode is arranged in the battery reaction tank; the air electrode is surrounded by a colloidal state zinc-rich material; and the air electrode is provided with an air supply system and an air purifying system. The injection type inner air electrode zinc air battery has the beneficial effects as follows: by virtue of the unique battery reaction tank configuration and the battery material supplying system, the zinc air battery can realize energy supplementation as a common internal combustion engine, so that the shortcomings that the negative electrode structure and the replacement way of the existing zinc air battery cannot satisfy vehicle power supply requirement and the air electrode is contaminated by dust easily can be avoided; and therefore, large-scale commercial application of the battery, as the internal combustion engine, can be realized.

Description

technical field [0001] The invention relates to a battery, in particular to an injection type 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 l...
