What is nanosilica powder?

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 has high purity and uniformity of distribution. This product is non-toxic, tasteless, and has high surface activity. Nano silicon is a new type of optoelectronic material with a wide gap energy semiconductor. It is also used as a high power light source.
Nano-silica powder can be prepared using the gas phase laser with variable current. It has features such as high purity, excellent dispersion, a small particle size, uniformity, large specific area, high activity on the surface, low bulk, good activity and a large industrialized output.

What is the use of nano-silicon powder?

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 surface material on nanosilicon powder, increasing 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-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 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 a laser plasma chemical gas phase process. This produces nano-sized silicon particles with high purity and low impurity levels, as well as good batch stability.
At the moment, most of nano silicon powders used in silicon anode materials are produced by ball milling and grinding with a Sand Mill. The output from a single mill is very low, and it is difficult to control the batch stability. Also, the preparation process, which requires grinding and dry, is quite complex. The stability of a batch cannot be guaranteed as grading, aggregate and other steps must be completed. 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% nano-silicon.
2. Tongrun Information Technology Co. Ltd. recommends adding about 8% nano silicon powder to lithium batteries with a capacity of 550.

The Applications of Nano Silicon Powder

/ / no Comments

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 loaded (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 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. High-purity silicon materials are capable of achieving high specific capacity without significantly affecting their cycle life.

Researches and application prospects of nano silicon powder

/ / no Comments

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 with high gap energy semiconductors, is also a high power light source material.
Nano silicon research is undergoing new developments
(1) Change the amount of silicon-rich and annealing conditions 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) The nanoSiO2/Si/SiO2 single-potential high-potential sandwich structure was created on a silicon substrate. It was produced using magnetron-sputtering technology. This allowed for visible electroluminescence. The changes in the thickness (W), which affects the Nano-silicon layer, cause the peak position and intensity for electroluminescence to oscillate synchroeously. 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 SiO2 :Si 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 bands (including 1.54mm to the near infrared) and the photoluminescence with the Forward or Retro bias Low threshold Voltage Electroluminescence. Furthermore, we proposed widely supported photoluminescence as well as electroluminescence models that provide the foundation for silicon-based optoelectronic Integration. It has significant scientific significance and great application potential.
