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.

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%.
Meishen is the world's leading
producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic
compound. It is a white solid at room temperature. Magnesium oxide exists in
the form of periclase in nature and is a raw material for magnesium smelting.
Magnesium oxide is white or light yellow powder, odorless, tasteless, this
product is insoluble in water and ethanol, melting point 2852 ° C, boiling
point 3600 ° C, magnesium oxide has high refractory insulation properties. It
can be converted into crystal by burning at a temperature above 1000 ° C. If it
rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.
Magnesium oxide can be used in the
manufacture of metallurgy, smelting, advanced magnesia bricks, refractory
materials and moisturizing materials. It is also widely used in rubber, rubber
sheet, rubber products, pharmaceutical industry, food industry, plastic sheet
accelerator, glass fiber reinforced plastics and Surface coating of silicon
steel sheet, paper production, steel ball polishing, leather treatment, insulation
materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.
Hebei Meishen Chemical Technology
Group is the main magnesium oxide producer in the world. It is also the largest
magnesium salt producer in China and has won the ISO9002 quality system
certification. It also has GMP-Certification.
With
rich experience in the research, development, production, management and
operation of magnesium oxide products, Meishen Group has always attached great
importance to the research and development of new products and strict
requirements on product quality. Meishen has a high-level sales team. The
business covers more than 20 countries and regions around the world. It is
