The main features of nano-silver Si Powder A variable current laser beam gas phase technique is used to prepare nano-silicon powder. The product has high purity and good dispersion, small particle sizes, uniform distribution, a large surface area, high activity on the surface, low bulk density and good activity. Nano silicon powder may be mixed with carbon nanotubes or graphite. For lithium-ion cells, a nanosilicon-carbon anode can be formed. It increases the capacity of the batteries as well as the cycle times. This is a new generation optoelectronic material with wide gap.

Nano silicon Si Powder Application
1. Use graphite on top of nano spherical powder as silicon anode for rechargeable batteries.
2. It is used as a raw material for organic silicon polymer and in coatings that are resistant to high temperatures.
3. Nanosilicon powder is applied to coatings in order to create a thin film with nano silicon particles. This technology is used widely for solar energy.
4. The nano-spherical powder of silicon and the diamond are mixed together under high pressure in order to produce a composite material called nano-silicon carbide—diamond, which can be used as a tool for strength and toughness.
5. The theoretical specific capacity of nano-silicon for lithium-ion batteries is 4200mAh/g, which is higher than the carbon material.
6. On the nanosilicon substrate are designed ten types of nanosilicon particles/silicon dioxide nano-structures, which produce photoluminescence under forward bias or reverse bias in the main wavebands from near ultraviolet to near infrared. Photoluminescence and Electroluminescence Models are proposed, which lay the groundwork for silicon-based optoelectronic Integration.
Processing characteristics of nanosilica powder
Tongrun Information Technology Co., Ltd. manufactures nano-silicon powder products using a laser plasma chemical gas phase process. The product obtained this way has uniform silicon particles, high purity and low impurity, as well as good batch stability.
Currently, the majority of nano-silicon powders used in silicon anode materials are produced by ball milling and grinding with a Sand Mill. The output from a sand mill can be low, and batch stability cannot be controlled easily. Also, the preparation process, which requires grinding and dry, is difficult. Grading, Agglomeration, as well as other steps, are performed, but batch stability can’t be guaranteed. The sanding procedure is complex and involves a large amount of equipment and machinery. The production line is out of order and the investment required is huge.

Suggested ratio :
1. Tongrun Information Technology Co. Ltd. recommends adding about 5% of the nano silicon powder.
2. Tongrun Information Technology Co. Ltd. recommends adding about 8% nano silicon powder to lithium batteries with a capacity of 550.
3. Tongrun Information Technology Co. Ltd. recommends adding about 10% of the nano-silicon from Tongrun Information Technology Co. Ltd.
4. Tongrun Information Technology Co. Ltd. offers a nano-silicon product that can be added to lithium batteries.
5. Tongrun Information Technology Co. Ltd. offers a nano silicon powder that can be added to the lithium battery.

Packaging and Storage
The packaging is made of inert gases and anti-static. This product should be kept in a cool and dry environment. It shouldn’t be exposed to air too long, as moisture can cause agglomeration and affect the use and dispersion effect.
