What is the property of nano silicon powder?
Nano silicon powder refers to crystalline silicon particles with a diameter of less than 5 nanometers (one billion (1G) of a meter). Nano silicon powder has the characteristics of high purity, small particle size and uniform distribution. With the characteristics of large surface area, high surface activity, and low bulk density, the product is non-toxic and tasteless. Nano silicon powder is a new generation of optoelectronic semiconductor materials with wide gap energy semiconductors and is also a high-power light source material.
Nano silicon powder is prepared by the variable current laser ion beam gas phase method. It has high product purity, good dispersion performance, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density, good activity, and large industrialized output Features.
What is the application of nano silicon powder?
1. Use nano silicon powder to make nano silicon wire in the negative electrode material of rechargeable lithium battery, or use graphite on the surface of nano silicon powder as the negative electrode material of rechargeable lithium battery, which increases the capacity and the number of charge-discharge cycles of rechargeable lithium batteries by more than 3 times.
2. Nano silicon powder is used in high temperature resistant coatings and refractory materials, and can react with organic matter as the raw material of organic silicon polymer materials;
3. Nano silicon powder can be applied to coatings to form a thin film of nano silicon particles, which is widely applied to solar energy;
4. Nano-spherical silicon powder and diamond are mixed under high pressure to form nano-silicon carbide---diamond composite material, which is used as a cutting tool to provide strength and toughness;
5. As a nano-silicon-carbon anode material for lithium-ion batteries, nano-silicon powder has a high theoretical specific capacity (theoretical value of 4200mAh/g), which is much higher than that of carbon materials;
6. Ten kinds of nano-silicon particles/silicon oxide nano-structures are designed on the nano-silicon substrate to realize the photoluminescence of the main wavelength bands from near ultraviolet to near infrared and low threshold voltage electroluminescence under forward or reverse bias, and proposes photoluminescence and electroluminescence models to realize silicon-based optoelectronic integration lay the foundation.
