Alkaline zinc manganese battery positive pole: electrolyte MNO2 powder, negative pole: zinc powder, electrolyte: KOH aquatic solution.
The reaction equation of alkaline zinc -manganese batteries:
Battery symbol: (-) Zn | KOH | MNO2 (+)
The electrode reaction is
Negative poles: Zn+20H-2 → Zn0+H? 0
Positive report: 2mn0?+2H? 0+2E → 2mn00h+20Hˉ
Total response: Zn+2mn0?+H? 0 → 2mn00h+Zn0
The requirements for alkaline zinc -manganese dry batteries for diaphragm:
1. The appearance should be uniform, flat, and no mechanical impurities;
2. Have good chemical corrosion ability;
3. Have good mechanical strength;
4. Have good electrolyte absorption ability and ability to maintain electrolyte;
5. There is a good size stability in the electrolyte;
6. Have good ionic conductivity 7. The content of metal impurities should be low;
