Method for improving shelf performance of metal air battery and metal air battery system
提高金属空气电池搁置性能的方法及金属空气电池系统
Abstracts:
The invention discloses a method for improving the shelf performance of a metal-air battery, which includes the following steps: (1) completely emptying the electrolyte of the metal-air battery after shutdown and storing the discharged electrolyte; (2) adopting a pH value The cleaning solution that has always been neutral is used to circulate the inside of the metal-air battery; (3) put the metal-air battery aside; (4) completely transport the stored electrolyte into the metal-air battery before starting the metal-air battery. The method provided by the invention can improve the storage performance of the metal air battery. The invention also discloses a metal-air battery system. The first loop formed by the metal-air battery and the electrolyte tank is provided with a circulation control device, and the second loop formed by the metal-air battery and the cleaning liquid tank is provided. There is a circulation control device, and the cleaning liquid tank is provided with a pH adjustment device for keeping the pH value of the cleaning liquid to be neutral.

Flexible zinc air battery for electric passenger boarding ladder and preparation method
一种用于电动旅客登机梯的柔性锌空气电池及制备方法
Abstracts:
The invention discloses a flexible zinc-air battery for electric passenger boarding ladders and a preparation method. The battery includes a zinc electrode, a modified biochar electrode and an electrolyte. The zinc electrode is used as a positive electrode, and the modified biochar electrode is used as a negative electrode. The electrolyte is set between the zinc electrode and the modified biochar electrode. The electrolyte is a KOH-PVA gel electrolyte. The modified biochar electrode adopts manganese dioxide modified biochar and is bonded to the surface of the base material through a binder. Made by roll forming. The flexible zinc-air battery of the invention has good air permeability, conductivity, high power density and stability, and low price.
