Problems solved by technology

However, in the current zinc-air battery technology, in order to improve the reaction rate and completeness of the reaction, so as to make the performance of the zinc-air battery better, there are still many things to be improved in terms of structural design.
[0005] Furthermore, the power density of general zinc-air batteries is poor, so when a large amount of power supply is required, it is easy to cause insufficient power supply.

Embodiment Construction

[0038] refer to figure 2 As shown, it shows a cross-sectional view of the anode plate 1 of the present invention. The anode plate 1 includes a current collector 11 , a reaction auxiliary layer 12 and a reaction layer 13 . The collector sheet 11 is generally made of metal materials such as copper and silver. The reaction auxiliary layer 12 can be made of metal materials including aluminum, zinc, magnesium, iron, etc. The reaction layer 13 can be made of metal materials containing zinc, aluminum, iron or magnesium. The reaction layer 13 is interposed between the current collector sheet 11 and the reaction layer 13, and the three form a composite sandwich structure, and the sandwich structure further forms a fin structure.

Abstract

A fine-like anode structure of a metal air fuel battery includes a collector plate, a reaction layer and an assistant reaction layer between them, a projection forms a fin structure at a side of the said anode structure including multiple fins projectes at a side of the anode structure and multiple air-through zones formed at the anode plate, every fin includes a levelling plate in horizontal direction and an open terminal tilting downward or bending at the end of the leveling plate, the compound sandwiching structure can be a wave structure.

Description

technical field [0001] The invention relates to a structure of a metal-air fuel cell, in particular to an anode structure of a metal-air fuel cell with a convection through-hole and a fin structure. Background technique [0002] In recent years, the development of batteries can be said to be various, such as lead-acid batteries, zinc-manganese dry batteries, nickel-cadmium batteries, nickel argon batteries, lithium-ion batteries, lithium polymer batteries, zinc-air batteries, etc. Among them, the zinc-air battery has the highest energy density among all electrolyte-based battery systems today, and its cathode reaction uses air as the reactant. Zinc reacts with oxygen in the air to form zinc oxide to release energy, so that chemical energy is released in the form of electrical energy. [0003] figure 1 A structural perspective view of a typical zinc-air battery is shown, which mainly includes a plate-shaped zinc fuel plate 1 and a cathode plate 2, wherein the zinc fuel plat...
