Nanometer magnesium oxide is a new type of nanoparticle material with a white appearance, high purity, large specific surface area, and composed of very fine grains with good dispersion and relative density of about 3.58 (25?).

Melting point 2852?, boiling point 3600?. Insoluble in water.

Nanoscale magnesium oxide has obvious small size effect, surface effect, quantum size effect and macroscopic tunneling effect. After modified treatment, there is no agglomeration phenomenon. It has many specific functions and important application value in optical, catalytic, magnetic, mechanical, chemical and other aspects.

Technical indicators:

Project indicators Vk-mg30d Magnesium oxide % 99.9 Diameter: 30nm calcium PPM <3 Chloride PPM < 3 PPM iron & lt<3 Burning loss %, & LT< 0.3 specific surface m/g 60-100

Application characteristics in lithium batteries:

1. Application in lithium battery

By adding an appropriate amount of nanometer magnesium oxide to the anode material of lithium ion battery, the anode material obtained has a reversible discharge capacity greater than 140mAh/g and good cycling performance.

Use in positive electrode materials can improve the conductivity, recommended additions of 0.3-0.5%.

2. Application of zinc-Nickel battery

The addition of magnesium oxide to the zinc negative active substance by physical mixing method can reduce the polarization of charge and discharge, reduce the internal resistance in the late cycle, improve the utilization ratio of the negative plate active substance, and extend the cycle life of the battery. The appropriate addition amount of magnesium oxide is 1.0%wt, and the addition amount should not exceed 2.0%.
