Top 10 silicon based anode companies in the world

As the market's requirements for the mileage of new energy vehicles continue to increase, it is necessary to develop new anode materials with higher gram capacity and increase the energy density of lithium batteries for lithium ion battery anode material companies. Due to its extremely high energy density, silicon materials can achieve high capacity and long service life through modification, and are expected to become the mainstream direction of research and development of anode materials for next-generation high-energy-density lithium batteries.

As Tesla, CATL and other companies have successively mass-produced high-density power battery products using silicon-carbon anodes, the demand for silicon-carbon anodes has blown out. Below, this article counts the top 10 silicon based anode companies in the world, in no particular order.
