Hebei Messi Biology Co., Ltd. stated that nano-magnesium oxide has obvious small size effect, surface effect, quantum size effect and macroscopic tunnel effect, and has many special functions and important application values in electronics, magnetism, mechanics, chemical engineering, etc.
1. In lithium cobalt oxide batteries: the doping of magnesium ions in nano-magnesium oxide can form a solid solution, stabilize the lattice, and improve the cycle performance.
2. Adding nano-magnesium oxide as a deacidifying agent to the electrolyte of lithium-ion batteries with spinel lithium manganese oxide as the positive electrode material, the addition amount is 0.5-20% of the electrolyte weight, which can improve the capacity and cycle performance of LiMn2O4.
3. The positive electrode material of lithium-ion batteries, with the addition of an appropriate amount of nano-magnesium oxide, has a reversible discharge capacity of more than 140mAh/g and good cycle performance. And it can improve the problem of capacity attenuation of the material during the cycle. The recommended addition amount is 0.3-0.5%.
4. In zinc-nickel batteries: it can reduce the charge and discharge polarization, reduce the internal resistance in the later stage of the cycle, improve the utilization rate of the negative plate active material, and extend the battery cycle life. The appropriate amount of magnesium oxide added is 1.0%wt.
5. High zinc chloride battery: 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. It is recommended to add 0.5-1% and adjust the appropriate pH value.
6. Cadmium-nickel battery: adding an appropriate amount of magnesium oxide, zinc oxide and iron oxide to the cadmium electrode can improve the utilization rate of the active material; adding magnesium oxide, indium trioxide and zinc oxide can improve the charge retention capacity of sealed cadmium-nickel batteries.
