Abstract

This utility model discloses a zinc-air battery power bank with a thick adhesive sticker, comprising a thick adhesive sticker, a shell, a zinc-air battery module, and a charging cable. The key feature is that the zinc-air battery module consists of four zinc-air batteries connected in series. The charging cable is connected to the positive and negative terminals of the zinc-air battery module. The zinc-air battery module is placed inside the shell, and the charging head of the charging cable is on the outside of the shell. The thick adhesive sticker is fixed to one side of the shell and contains gas diffusion channels. The four zinc-air batteries in the zinc-air battery module are stacked tightly in two layers, two batteries per layer, with the positive terminal of the upper layer facing upwards and the positive terminal of the lower layer facing downwards. The stacked structure of the four zinc-air batteries in this utility model fully utilizes the surface area of ​​the zinc-air batteries, significantly reducing the size of the power bank. The structure of the thick adhesive sticker solves the problem that this extremely small zinc-air battery power bank cannot be attached to the back of a mobile phone.
