Embodiment Construction

[0018] Specific examples of the present invention are given below. The specific embodiments are only used to further describe the present invention in detail, and do not limit the protection scope of the claims of the present application.

[0019] The invention provides a zinc-air battery pack with a column type single cell (see Figure 1-5 , referred to as the battery pack), including a top plate 1, a single cell 2 and a grid 3; 26. Terminal post 27 and top cover 28;

[0020] One end of the grid plate 3 is connected to the top plate 1, and the other end is connected to the base 24. The grid plate 3 is distributed around the entire battery pack, and its effect is to control the degree to which the external air of the battery pack enters the reaction column 21 and fixes the top cover 28; The top plate 1 has a top plate hole 11, and the outer surface of the top plate 28 fits in the top plate hole 11 to realize the connection between the top plate 1 and the single battery 2, an...

Abstract

The invention discloses a zinc air battery pack with column-type single batteries. The zinc air battery pack comprises a top plate, single batteries and a gate plate, wherein each single battery comprises a reaction column, connecting parts, pole pieces, a base, electrolyte circulating openings, a zinc electrode rod, a binding post and a top cover. The single battery is firm in structure, so that the modular design of the battery pack is realized; namely, every one group of single batteries can be arranged in one body, so that the maintenance, the replacement and disassembly of the battery pack can be convenient and rapid; in addition, the number of the single batteries in the battery pack can be adjusted at any time according to needs of actual application; the bases of the single batteries are connected through connecting pipes, so that the electrolyte can be connected, and the overall circulation and replacement of the electrolyte can be realized conveniently; therefore, the shortcoming of uneven specific energy output of the single batteries in the use process of the battery pack caused by difference of reaction environments can be overcome; and in addition, influences on the productivity of the battery pack caused by adverse factors, such as electrolyte solute loss, the reaction heating of the battery pack, and the like in the working process of the battery pack can be reduced.

Description

technical field [0001] The invention belongs to the field of battery assembly, in particular to a column-type single battery zinc-air battery pack. Background technique [0002] With the continuous improvement of people's awareness of environmental protection and energy requirements, the development of electric vehicles and the energy used by electric vehicles has been driven. As the power source of electric vehicles, the battery pack has become a key factor restricting the development of the electric vehicle industry. At this stage, the battery packs widely used in electric vehicles are mainly lithium batteries, but in order to improve the mileage of electric vehicles after a single charge, it is currently proposed to focus on metal-gas batteries, such as aluminum-air batteries, zinc-air batteries, etc. . Among them, zinc-air battery has the highest theoretical energy capacity among all known fuel cell types, and has become a new generation of energy to replace other powe...
