What is the nanosilicon powder property?

Nano silicon powder The term crystalline silicon is used to describe particles that are less than 5 nanometers in diameter (one billion (1G), of a meter). Nano silicon powder is known for its purity, small particles and uniform distribution. This product is non-toxic, tasteless, and has high surface activity. Nano silicon is a new type of optoelectronic material with wide gap energy and high-power light source.
Nano-silica powder can be prepared using the gas phase laser with variable current. It has a high level of purity, good performance in dispersion, uniformity, large specific area, high surface activation, low bulk densities, good activity and large industrialized output.

How can nanosilica be used?

1. You can use nanosilicon powder to make nanosilicon wires in the negative electrode materials of rechargeable Lithium batteries, or you can use graphite as the negative electrode materials of rechargeable Lithium batteries. This will increase the capacity and number of charge-discharge cycling of rechargeable Lithium batteries by 3 times.

2. It is used as a raw material for organic silicon polymer materials and high temperature resistant coatings.

3. Nanosilicon powder is applied to coatings in order to form a thin, film-like layer of nanosilicon particles. This technology is used widely for solar energy.

4. The nano-silicon carbide-diamond composite is formed by mixing silicon powder with diamond under high pressure. It can be used as a tool for strength and toughness.

5. The theoretical specific capacity of nano-silicon for lithium-ion cells is 4200mAh/g, which is higher than the carbon material.

6. On the nano-silicon surface, ten different nano-silicon structures are designed. These nano-structures can be used to produce photoluminescence for the main wavelength ranges from near UV to near Infrared as well as low threshold voltages electroluminescence.

Processing characteristics of nanosilica powder
Tongrun Information Technology Co., Ltd. manufactures nano-silicon powder products using the laser gas phase chemical plasma method. The product obtained this way has uniform silicon particles, high purity and low impurity, as well as good batch stability.
The majority of nano silicon powders used in the silicon carbon anode material at home and abroad are produced by ball milling and grinding with a Sand Mill. The output from a sandmill is low and batch stability is difficult to control. Also, the preparation process, which requires grinding and dry, is complex. Grading, Agglomeration and many other steps are done, but batch stability can’t be guaranteed. Sanding requires complex machinery and equipment. The production line is out of order and the investment required is huge.

The Applications of Nano Silicon Powder

Overview Nano Silicon Powder
The most promising electrode material for next generation lithium-ion batteries is silicon. Its specific capacity (3600mAh/g) is more than 10 times that of graphite (372mAh/g). The material’s significant expansion (more than 300%) in the loaded state (lithiation), and the instability of its solid electrolyte interface (SEI) make it a restricted choice. Poor mechanical stability and chemical passingivation properties make silicon electrodes difficult to cycle. There has been a lot research into these issues and many suggestions for ways to overcome them.
The volume of silicon changes during lithium insertion. It is about 400%. When this happens, the silicon cracks and falls from the collector. The prototype lithium-silicon lithium-ion battery loses most of its capacity in a few charge and discharge cycles. Lithium-ion silicon’s stability and capacity issues are the keys to the success of large-capacity, high-capacity batteries.
Anode materials made of silicon have great potential to improve the efficiency and energy storage capacities of lithium-ion cells. The main drawback of silicon anode materials was their surface passivation via oxidation. This is a process that increases impedance while decreasing the circularity. Our silicon anode materials are high-purity and can achieve high specific capacitiy without significantly reducing cycle life.

What is Nano silicon? Nano silicon The smallest diameter of crystal silicon particles is 5 nanometers. Nano silicon powder is high in purity and has small particles. It also has uniform distribution. This product is tasteless and non-toxic thanks to its high surface area, high activity and low bulk density. Nano silicon powder, a new generation optoelectronic materials, is a high-power source material and has a wide gap energie semiconductor.
Nano silicon research is undergoing new developments
(1) Change the amount of silicon-rich, the annealing conditions, and other factors to control the size or density of silicon nanocrystals. The critical temperature required for the formation of silicon nanocrystals has been suggested by the literature as being 1000oC. We have proved this through experiments. After annealing at 900oC, the high-resolution electron photo of silicon-rich silicone oxide has a silicon content of around 30%. It is obvious that silicon nanocrystals exist.
(2) First time observation of the electroluminescence in Au/(Ge/SiO2) superlattice/p–Si structures. High-resolution electron micrograph showing a four-period Ge/SiO2 supra lattice. The bright-line shows SiO2 having a thickness of 2.0nm. The Ge layer has a thickness at 2.4nm.
(3) A nanoSiO2/Si/SiO2 single-potential high-potential sandwich structure was created on the silicon substrate. It was first realized that visible electroluminescence from the Au/NDB/pSi structure could be achieved. It was found that the intensity and peak positions of electroluminescence oscillate synchroeously with changes in the thickness (W), of Nano-silicon. Further research and analysis have proven that the oscillation time is 1/2 of the de Broglie wavelength. This is explained by the electroluminescence theory proposed by our group.

(4) Er electroluminescence (with a wavelength 1.54mm) was first realized using the SiO2Si:Er film grown by magnetron-sputtering.
(5) First time, a UV-violet luminescence of 360nm at a low threshold voltage was achieved in heat-treated natural silicon oxide/pSi. It is the longest wavelength known to be produced by silicon-based ultravioletescence.
The applications prospects for Nano silicon
We have developed more than 10 types of silicon/siliconoxide nanostructures and realized the photoluminescence within the main wavelength band (including 1.54mm, 1.62mm, from the near ultraviolet to the near infrared) and the photoluminescence with the forward or reverse bias Low-threshold voltage electroluminescence. Our photoluminescence model and widely supported electroluminescence models provide the foundation for silicon-based optoelectronics integration. It has significant scientific significance and great application potential.
