30-50nm High purity spherical nano silicon powders suppliers in china

Superfine high purity silicon nanoparticles used in semiconductor materials,lithium-ion materials, solar cells,etc.

The nano silicon powder has the characteristics of high purity, small particle size, uniform distribution, large surface area, high surface activity and low bulk density. Nano-silicon powder is a new generation of optoelectronic semiconductor materials with a wide gap energy semiconductor and a high-power light source material.

Silicon nanopowders sepcification: 30-50nm 99%+, brown yellow, good spherical 100-200nm 99.9%+,brown black, irregular crystal form 300-500nm 99.9%+,brown black, irregular crystal form 1-2um 99.9+%, dark brown, irregular crystal form Silicon nanopowder properties: High purity, good dispersion performance, small size, uniform distribution, large surface area, high surface activity, low apparent density. Nano Silicon powders is non-toxic, odorless, and with active features. Nano silicon powder is a new material for high capacity lithium battery anodes. Silicon nanopowders use for the rechargeable lithium battery cathode material: Due to the high absorption rate of nanometer silicon and lithium batteries, the nano silicon for lithium can significantly increase the capacity of lithium battery (theory can reach 4000mA / h). Nano silicon powder and graphite replace the nano carbon powder as raw materials for the lithium anode material, use the mechanical milling method for preparing the best ratio of silicon / graphite composites, silicon and graphite, which is 1:9. Composition Si-C composite material, can effectively reduce the expansion when silicon absorption lithium ions, increase the affinity with the electrolytic solution, and easily dispersed and can improve the cycle performance. Nano silicon nanowires made of silicon powder used in rechargeable lithium battery anode material in or on the surface of the nano silicon powder coated graphite anode materials used in rechargeable lithium battery, rechargeable lithium batteries can be improved more than three times the capacity and charge-discharge cycles.
