nano silicon applied in lithium ion battery

Our product SILICON has four features of high purity,small particle,uniform diameter distribution,high surface activity,large specific surface area.Our silicon particle could effectively decrease the expansion resulting from silicon absorbing the lithium ion,reduce teh loss of silicon,and improve the recycle capacity. With the vapor method,the nanno silicon particle has higher surface activity,easily to match with many kinds of material to form composite materials. As that it is more flexible in applications.Our technology is: coat the surface of silicon with carbon material,then from Si-C composite material. Nano Si-C composite material not only has high recycle and stability character as the same with the carbon material,which could prevent the silicon material from activity loss of lithium embedded due to volume expansion and migration,but also has the feature of high specific capacity as the same with Si material.
