Product Details:

SiOx/C composite silicon based anode is a trending anode material for lithium ion battery due to their high capacity. This product is manufactured through unique technologies, such as hollowing, nanolization and surface modification. It has low volume expansion, long cycling life and high capacity. Li2O, generated by the reaction of Li with SiOduring the initial lithiation process, can act as a buffer component to improve the cycling performance of electrode. Carbon in the composite improves the electronic conductivity and prevents the agglomeration of nanoscale Si. This product can be used for lithium ion battery with high capacity need.
