an air battery

Abstract

The invention discloses an air cell. The air cell comprises a cell reaction body with a reaction cavity, a positive electrode assembly, a negative electrode assembly and a combined connecting cover, wherein a first connecting column and a second connecting column are arranged at the two ends of the cell reaction body; the first connecting column and the second connecting column are equipped with external screw threads respectively; the combined connecting cover comprises a first connecting part and a second connecting part; and the first connecting part and the second connecting part are provided with inner screw threads matched with the external screw threads respectively. Due to the hollow combined connecting cover with the internal screw threads, and the fuel cell reaction body with the connecting columns which are equipped with the external screw threads, the problem in fastening and sealing the existing air fuel cell and the problem of electrolyte leakage can be well solved; the safe, efficient and consistent production requirement is satisfied; due to the design of the series connection holes of the electrodes, the condition that the voltage and current can be output in a serial connection manner only when the positive electrode and the negative electrode of the original air metal fuel cell are exported and welded can be avoided; and in addition, due to the hidden internal connecting mode, the problem of short circuit is avoided as well.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an air battery with good sealing performance and convenient series connection. Background technique [0002] The air metal fuel cell uses oxygen molecules in the air to pass through a catalytic reaction layer that can be sealed and water-proof, and uses alkaline electrolyte as a carrier to transfer to the surface of metal fuel zinc, aluminum, magnesium, and lithium for reaction to generate electron displacement. The energy battery that forms voltage and current, as a safe, efficient, clean and renewable green energy, has attracted worldwide attention. This battery has the following advantages and characteristics: [0003] 1. The battery has large capacity and high energy, which is more than 5 times that of traditional lead-acid batteries and more than 2 times that of lithium-ion batteries currently in use. The weight of the same volume is only a quarter of that of lead-acid bat...

AI Technical Summary

Problems solved by technology

Although the air metal fuel cell has so many advantages, there are still some disadvantages: the air metal fuel cell has both alkaline liquid and metal alloy in the reaction process, and oxygen molecules, electrolyte, and metal alloy must be completely organically unified to form both Oxygen molecules can be used to store electrolytes, allowing metal alloys to react with oxygen molecules to achieve the functions of sealing, series connection, storage and reaction
