Silicon nanoparticles are spherical high surface area metal particles. Nanoscale silicon Particles are typically 50 nanometers (nm) with specific surface area (SSA) in the 80 m 2 /g. Surface functionalized nanoparticles allow for the particles to be preferentially adsorbed at the surface interface using chemically bound polymers. Nano silicon powder provides higher activity, good ductile, wide energy gap and high-power lumination. Development research is underway in Nano Electronics and Photonics materials.
Silicon Nanoparticles is suitable for lithium battery electrode materials and have been shown to dramatically expand the storage capacity of lithium ion batteries without degrading the silicon during the expansion/contraction cycle that occurs as power is charged and discharged. Silicon has long been known to have an excellent affinity for storage of positively charged lithium cations making them ideal candidates for next generation lithium ion batteries. Now, we are cooperating with research organizations of China to research the silicon -coated graphite as the anode of lithium ion battery. The silicon-graphite composite anode materials can reduce the swelling when silicon absorbs lithium ion, and also can increase the affinity between silicon and electrolyte, easy to disperse, improve the performance of lithium ion circle. 
Nano silicon powder is the material of organosilicone polymers by reacting with organic materials. Metallic silicide can used to be made polycrystalline silicon.
