Application Prospects of Nano-Silicon

Nano silicon  overview

Nano-silicon refers to crystalline silicon particles smaller than 5 nanometers (one billion (1G) one meter) in diameter. Nano silicon powder has the characteristics of high purity, small particle size, uniform distribution, large specific surface area, high surface activity, looseness, low bulk density, non-toxic and tasteless. Nano silicon powder is a new generation of optoelectronic semiconductor materials, a semiconductor with a wide energy gap, and a high-power light source. Nano-silicon can be combined with graphite, carbon nanotubes or nano-nitrogen, combined with compounds such as titanium dioxide to make a positive electrode material for lithium batteries, which can improve the capacity and service life of lithium batteries. It is a new generation of electro-optical semiconductor materials with a huge energy gap.

We have designed more than a dozen silicon/silicon oxide nanostructures on silicon substrates to achieve photoluminescence in all major wavelength bands (including 1.54 and 1.62 μm) from near-ultraviolet to near-infrared and under forward or reverse bias. Low threshold voltage electroluminescence, and a widely supported photoluminescence and electroluminescence model are proposed, which lays a certain foundation for the ultimate realization of silicon-based optoelectronic integration. It has important scientific significance and huge application prospects.

Application of nano silicon powder

1. Use nano-silicon powder to make nano-silicon wires for positive electrode materials of rechargeable lithium batteries,

Or used as a positive electrode material for rechargeable lithium batteries in herringbone graphite on the surface of nano-silicon powder.

Increase the capacity and charge-discharge cycle index of rechargeable lithium batteries by more than 3 times;

2. Nano silicon powder is used in heat-resistant coatings and refractory materials;

3. Nano-silicon can be coated in the coating to form a silicon nano-film and recoat solar energy;

4. Rice silicon powder and diamond are mixed under high pressure to form a silicon carbide-diamond composite material, which is used as a cutting tool.

This product should be stored in a dry,cool and airtight environment and should not be exposed to air. Also, please avoid heavy pressure and transport it as a normal item.
