Rechargeable zinc-air battery

Abstract

The invention discloses a rechargeable zinc-air battery, and belongs to the field of zinc-air batteries, the rechargeable zinc-air battery comprises a battery and a shell, the shell comprises an inner shell, an outer shell and a bottom shell which are detachably mounted, the inner shell is fixed on the outer side of the battery, the outer shell sleeves the outer side of the inner shell, and a buffering cavity is arranged between the inner shell and the outer shell; a plurality of buffering mechanisms are arranged in the buffering cavity, limiting mechanisms are arranged at the corners of the buffering cavity, air holes are symmetrically formed in the two sides of the outer shell, air pipes are installed in the air holes, motors are installed in the air pipes through supporting frames, and fans are installed at the driving ends of the motors. According to the zinc-air battery disclosed by the invention, heat dissipation treatment and shock absorption treatment can be performed on the battery through arrangement of each structure, liquid leakage caused by breakage of a battery shell due to external collision is avoided, influence on charging and discharging efficiency due to temperature rise of the battery is avoided, and normal use of the battery is facilitated.

Description

technical field [0001] The invention relates to the technical field of zinc-air batteries, in particular to rechargeable zinc-air batteries. Background technique [0002] Zinc-air battery is a primary battery that uses activated carbon to absorb oxygen or pure oxygen in the air as the positive electrode active material, zinc as the negative electrode, and ammonium chloride or caustic alkali solution as the electrolyte. Also known as zinc-oxygen battery. Zinc-air batteries are divided into two systems: neutral and alkaline. [0003] After retrieval, Chinese Patent No. CN10410615B discloses a zinc-air battery, a pool, including at least one structure with zinc, at least one oxygen-evolving structure and at least one air electrode; wherein, the zinc-air battery includes a first pair of electrodes to use For charging the air battery, the electrode pair includes the at least one zinc-containing structure and the at least one oxygen-evolving structure; and wherein the zinc-air b...

AI Technical Summary

Problems solved by technology

[0004] Zinc-air batteries will generate a certain amount of heat during use, causing the temperature of the battery body to rise. On the one hand, it will affect the charging and discharging efficiency of the battery, and on the other hand, it will also affect the safety of the battery; in addition, the battery does not have the function of shock absorption and buffering. As a result, after being subjected to external collision and vibration, it is easy to cause the shell to be damaged and leak, which also affects the safety of the battery. Therefore, in view of the above-mentioned technical defects of the zinc-air battery, the present invention proposes a rechargeable zinc-air battery.
