1. Application in zinc-nickel batteries
Hebei Messi Biology Co., Ltd. stated that by physically mixing nano magnesium oxide into zinc negative electrode active materials, it can reduce charge and discharge polarization, reduce internal resistance in the later stage of the cycle, improve the utilization rate of negative plate active materials, and extend the battery cycle life. The appropriate amount of nano magnesium oxide added is 1.0%wt, and the amount added should not exceed 2.0%.
2. Application in high zinc chloride batteries
Adding a small amount of nano magnesium oxide to the positive electrode active material can adjust the acidity of the electrolyte, slow down self-discharge, inhibit battery bloating, improve storage performance, and has a unique effect on increasing discharge capacity and promoting slurry gelatinization. The recommended addition amount is 0.5-1%, and the appropriate pH value is adjusted.
3. Application in cadmium-nickel batteries
Adding an appropriate amount of nano magnesium oxide to the cadmium electrode can improve the utilization rate of the active material; adding nano magnesium oxide can improve the charge retention capacity of sealed cadmium-nickel batteries.
4. Others
Adding an appropriate amount of nano magnesium oxide to the positive electrode material of lithium batteries can improve the problem of capacity attenuation during the cycle of the material. Using it in dye-sensitized solar cells can improve the utilization rate of light and the photoelectric conversion rate.
