Main features of nano silicon Si powder
Nano silicon powder is prepared by a variable current laser ion beam gas phase method. The product has the characteristics of high 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. Nano silicon powder can be compounded with graphite, carbon nanotubes, etc. to form a nano silicon carbon anode material for lithium-ion batteries, which can increase the capacity and cycle times of lithium-ion batteries and prolong the service life. It is a new generation of optoelectronic semiconductor materials with wide gap energy.

Nano silicon Si powder application
1. Use nano silicon powder particles to make nano silicon wires for use in nano silicon carbon anode materials for rechargeable lithium batteries, or use graphite on the surface of nano spherical silicon powder as silicon carbon anode materials for rechargeable lithium batteries, which improves rechargeable lithium batteries 3 The electric capacity and the number of charge and discharge cycles more than twice;
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, which realizes the photoluminescence in the main wavelength bands from near-ultraviolet to near-infrared and low threshold voltage electricity under forward or reverse bias. Luminescence, and proposed photoluminescence and electroluminescence models, laying the foundation for the realization of silicon-based optoelectronic integration.
Process characteristics of nano silicon powder
Luoyang Tongrun Information Technology Co., Ltd. produces nano silicon powder products that are synthesized by laser plasma chemical gas phase method. The products obtained in this way have uniform silicon particle size, high purity, low impurity content, good batch stability, and mass production Low cost, high-purity silane gas is used to obtain nano silicon powder particles in one step, the process is simple, the intermediate steps are few, and the product quality can be controlled.
At present, most of the nano silicon powder used in silicon carbon anode materials at home and abroad is obtained by grinding and ball milling with a sand mill. The output of a single sand mill is low, the batch stability is not easy to control, and the preparation process is complicated, requiring grinding and drying. , Grading, agglomeration and other multiple steps are completed, so the batch stability cannot be guaranteed. The sanding process uses a lot of machinery and equipment, and the process is complicated. The entire production line is down and the investment is large.
