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

Description

technical field [0001] The invention relates to a battery, in particular to a rotating whisker-shaped zinc electrode star-shaped air electrode 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 u...
