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.

    Silicon nano technology reforming graphite cathode lithium batteries
    Silicon nano technology reforming graphite cathode lithium batteries       Cathode technology of the existing lithium batteries has reached the limit. In order to meet the needs of a new generation of energy, the development of new cathode technology of lithium batteries is imminent. Silicon cathode, with the ultra-high specific capacity and rich reserves, has become one of the most representative new technology.     Compared to the traditional graphite cathode, a major obstacle to the Silicon cathode technology on the road of industrialization is that low gel content cause unsatisfactory effect of electrode mixing.     On account of this, some researchers integrated graphite cathode technology and Silicon nano technology and have developed a new and can be mass-produced C- nano Si- graphite composite cathode materials. During the lithiation process, Si nanoshells can be expanded as the volume change. No matter nano-Si hollow shell in the graphite , or a nano-Si intermediate layer between the graphite and carbon, it can keep the shape intact and not be broken or left over between Si and graphite. This special structure, on the one hand to ensure compatibility between the Si and natural graphite, on the other hand avoid the severe side effects caused by traditional mechanical mixing graphite powder and residual Silicon particles.     Silicon Nano Powder is generally immediately available here with particle size 30-50nm,100-200nm,300-500nm,1um.
