Product introduction:
With the continuous improvement of the energy density of lithium batteries, silicon anodes with high energy density have become the first choice for the next generation of lithium battery anode materials; SiO anode materials have the highest gram capacity of 2000mAh/g, which is more than 5 times that of graphite. The preferred negative electrode for cell high energy density; low electrochemical lithium intercalation potential (about 0.4 V vs. Li/Li+), no lithium precipitation problem.
Application field:
It is mainly used in chemical energy storage fields such as 3C digital, power tools and electric vehicles. It is the next generation of new energy storage anode materials. It has the characteristics of high capacity, low expansion, long life, and high rate. It can effectively improve consumer electronics, power Tools, battery life of electric vehicles.
