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 discloses a rotary whiskered zinc electrode cylindrical reaction tank air battery which comprises a battery reaction tank, an air electrode outgoing line and a zinc electrode outgoing line, and is characterized in that an upper orifice of the battery reaction tank is an opening and is provided with a movable reaction tank cover; the side face of the battery reaction tank is enclosed into a cylinder by an air electrode; a cheek-shaped protrusion is arranged on the surface of the air electrode; a cone is arranged at the bottom of the battery reaction tank; a zinc oxide outlet is formed in the lower end of the cone; the battery reaction tank is filled with electrolyte; and a zinc electrode is arranged in the battery reaction tank. The rotary whiskered zinc electrode cylindrical reaction tank air battery disclosed by the invention has the advantages that due to the unique air electrode and zinc electrode structure, the battery capacity is high, the zinc electrode replacement interval of the battery is long, and due to rotation of the zinc electrode, the zinc oxide is stripped to drop from the zinc electrode and then is dissolved, so that the reaction on the zinc electrode can be continued, and the defect that the battery performance is reduced due to the zinc oxide coating is overcome. According to the previous characteristics, the air battery can meet the requirement on vehicle power.

Description

technical field [0001] The invention relates to a battery, in particular to a cylindrical reaction tank air battery with a rotating whisker-shaped zinc electrode, and 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, s...
