Rotary bearded zinc electrode/gilled air electrode zinc air battery

Abstract

A zinc-air battery with rotating whisker-shaped zinc electrode and gill-shaped air electrode, including a battery reaction tank, air electrode lead-out wires, and zinc electrode lead-out wires, is characterized in that: the upper opening of the battery reaction tank is an open opening, and a movable reaction tank cover is provided The side of the battery reaction tank is surrounded by air electrodes into a star shape, and gill-shaped protrusions are arranged on the surface of the air electrode; a cone is provided at the bottom of the battery reaction tank, and a zinc oxide discharge port is provided at the lower end of the cone; The reaction tank is filled with electrolyte and is equipped with zinc electrodes. The invention uses a unique air electrode and zinc electrode structure to make the battery capacity large, and the interval between battery replacement of zinc electrodes is long. The rotation of the zinc electrodes makes zinc oxide peel off and dissolve from the zinc electrodes, so that the reaction on the zinc electrodes can continue. , overcoming the drawbacks of zinc oxide wrapping to reduce battery performance, the above characteristics enable zinc-air batteries to meet the requirements of vehicle power sources.

Description

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

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
