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 the power supply for vehicles, such as the need to replace the new electrodes after the mechanical plug-in zinc-air battery is discharged, are not conducive to commercial operation; in addition, as the discharge reaction progresses, zinc oxide wraps the zinc, hindering the reaction, making the The internal resistance of the battery increases, which reduces the utilization rate of raw materials and affects the performance of the battery

Abstract

The invention provides a zinc-air battery with whisker electrodes. The zinc-air battery comprises a battery reaction tank, an air electrode outgoing line and a zinc electrode outgoing line; the zinc-air battery is characterized in that an opening is formed in an upper opening of the battery reaction tank and is provided with a movable reaction tank cover; the side surface of the battery reaction tank is surrounded by an air electrode; the battery reaction tank is full of an electrolyte and is provided with a zinc electrode; and the zinc electrode is provided with an ultrasonic vibrator. The zinc-air battery has the beneficial effect that energy supply can be achieved by the zinc-air battery like an ordinary internal combustion engine through unique battery reaction tank and zinc electrode, so that large-scale commercial application of the battery becomes possible. The manufacturing method of the zinc-air battery is economical and simple, massive production is easy to implement, and the zinc-air battery has a wide application prospect in the field of battery manufacturing.

Description

technical field [0001] The invention relates to a battery, in particular to a whisker-shaped 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 low-cost mat...
