Performance and application of nano silicon powder|

Nano silicon’s main characteristics


The variable current laser-ion beam gasphase method is used for the preparation of nanosilicon powder. High purity, high dispersion performance and small particle sizes are some of the attributes. The nanosilicon powder can also be combined with carbon nanotubes and graphite. Nano silicon carbon anode materials for lithium-ion cells can be made by combining graphite, carbon nanotubes and other elements. This will increase their capacity and cycling times and extend the battery’s service life. The new optoelectronic materials have a large gap energy and are a new type of semiconductor material.

Nano silicon


Pulver application

1. To make tiny silicon particles for nano silicon wires, you can use graphite to coat nano-spherical silica powder. This improves the electric power and reduces the amount of discharge and charge cycles.

2. Use nanosilicon powder for high temperature resistance coatings and refractory substances.

3. You can use nano silicon powder on coatings to create a thin layer of tiny silicon particles. This technique is used extensively in solar energy.

4. To create nanosilicon carbide—diamond compound material, high-pressure mixtures of silicon powder and diamond result in nano-silicon crystals. The composite material is used for cutting to increase strength and toughness.

5. The theoretical specificity of nano-silicon, a nanosilicon-carbon material used as an anode in lithium-ion cells for their batteries is high (theoretical value 4200mAh/g). This is far greater than what you would get from carbon materials.

6. The nano-silicon substrate is capable of generating photoluminescence using ten kinds of nano-silicon nanostructures/silicon oxide particles. This foundation was laid for the realisation of silicon-based optoelectronics integration by Luminescence.

The process properties of nanosilicon powder

Luoyang Tongrun Information Technology Co., Ltd. makes nano silicon powder products using laser plasma chemical phase method. These products are uniform in size and have low impurities. They can also be mass produced.

Most of the nano silicon powder in silicon carbon anode materials abroad and at home is produced by ball milling using a sandmill. One sand mill produces a low amount of powder, so batch stability and processing complexity are difficult. The batch stability of sand mills cannot be guaranteed because they have to perform multiple tasks such as grading and agglomeration. Complexity and heavy machinery are required for sanding. Investments are large and all production lines have to go down.

Ratio suggested


1. Maximum Lithium battery power: 450. Add about 5% to the Luoyang Tongrun Information Technology Co. Ltd.

2. The lithium battery’s capacity is 550. You should add approximately 8% nanosilicon powder from Luoyang Tongrun Information Technology Co. Ltd.

3. The lithium battery’s capacity is 650. However, you should add around 10% of the Luoyang Tongrun Information Technology Co. Ltd. nano silicon powder.

4. The lithium battery’s capacity is 750. You should add approximately 12% nanosilicon powder from Luoyang Tongrun Information Technology Co. Ltd.

5. Maximum Lithium battery power: 950. Add about 15% nano silicon powder to Luoyang Tongrun Information Technology Co. Ltd.
