Application characteristics in lithium batteries

1. Application in lithium batteries

Adding an appropriate amount of nano magnesium oxide to the positive electrode material of lithium-ion batteries results in a reversible discharge capacity greater than 140mAh/g and good cycling performance. The use of positive electrode materials can improve conductivity, and it is recommended to add an amount of 0.3-0.5%

2. Application in zinc nickel batteries

By adding magnesium oxide to the zinc negative electrode active material through physical mixing, it can reduce charge discharge polarization, reduce internal resistance in the later stage of cycling, improve the utilization rate of negative plate active material, and extend the cycling life of the battery. The appropriate amount of magnesium oxide to be added is 1.0% wt, and the amount should not exceed 2.0%.

3. Application in high chloride zinc batteries

Adding a small amount of magnesium oxide to the positive electrode active material can regulate the acidity of the electrolyte, slow down self discharge, suppress battery inflation, improve storage performance, and have a unique effect on increasing discharge capacity and promoting paste layer gelatinization. Suggest adding 0.5-1% and adjusting the appropriate pH value.

4. Application in cadmium nickel batteries

Adding appropriate amounts of magnesium oxide, zinc oxide, and iron oxide to cadmium electrodes can improve the utilization efficiency of active substances; Adding magnesium oxide, indium trioxide, and zinc oxide can improve the charge retention capacity of sealed cadmium nickel batteries
