Lithium battery specific nano magnesium oxide
Nano magnesium oxide is a new type of nano particle material, with a white powder appearance, high purity, large specific surface area, composed of extremely fine grains, non-toxic, odorless, good dispersibility, and a relative density of about 3.58 (25 ℃). Melting point 2852 ℃, boiling point 3600 ℃. It is insoluble in water, insoluble in alcohol, and soluble in acid or ammonium salt solutions. Nanoscale magnesium oxide has obvious small size effects, surface effects, quantum size effects, and macroscopic tunneling effects. After modification, there is no agglomeration phenomenon, and it has many special functions and important application values in optics, catalysis, magnetism, mechanics, chemical engineering, etc. Its prospects are very broad, and it is an important new material in the 21st century.

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
