Embodiment Construction

[0034] As shown in Figures 1-5, the metal-air battery system of the present invention

[0035] A metal-air battery system, comprising a cuboid case 1 with a cover 2 on the top, and the cover 2 is fastened on the top of the cuboid case 1;

[0036] The square housing 1 is a cylindrical structure with an upper opening, a closed perimeter and a bottom. Inside the square housing 2, 2n partitions are vertically arranged in parallel from left to right, where n is a positive integer ≥ 1, and the partitions It is airtightly connected with the inner side wall and the inner bottom surface of the housing 1 to form an integrated structure;

[0037] Seal above each partition and seal vertically upward on the inner side walls of the housing close to the front and rear sides of the partition above the partition to form a "U"-shaped sealing groove; insert vertically in the sealing groove The air cathode, the air cathode 4 and the housing 1 form an integrated structure, and the air cathode and...

Abstract

The invention relates to a metal-air battery system. Two or more air cathodes of the metal-air battery system are inserted into a hollow cuboid shell in a pluggable connection and parallel mode to form an integrated structure; one or more metal anodes in the metal-air battery system is/are fixed on a cover plate in a replaceable connection and parallel mode to form an integrated structure; and the metal anodes on the cover plate are inserted into a cavity formed by the two air cathodes in turn, and covered by the cover plate to form the metal-air battery system. Compared with the prior art, the structure of a battery pack is more compact and firmer, the air cathodes and the metal anodes are easy to replace, the use and maintenance are more convenient, the cost is lower, the problem of difficult H2 exhaust is solved, and the metal-air battery system is suitable for an emergency power supply, an electronic product power supply and a power source which need high energy.

Description

technical field [0001] The invention relates to a metal-air battery, specifically a metal-air battery system, which is a metal-air battery pack with an integrated structure, which can be used as a high-energy power source such as an emergency power source, a power source for electronic products, and a power source for power. Background technique [0002] A metal-air battery uses a metal anode as a fuel and oxygen in the air as an oxidant to convert the chemical energy of the fuel into electrical energy. It consists of a metal anode, an aqueous solution of salt or alkali as an electrolyte, and an air cathode. Commonly used metal anode materials are Mg, Al, Zn, Fe, Li and their alloys, and the cathode active material is oxygen in the air. The corresponding batteries are called magnesium / air batteries, aluminum / air batteries, zinc / air batteries, and iron / air batteries. , Lithium / air battery. Magnesium / air battery electrolyte is generally NaCl aqueous solution (or seawater), e...
