Global top 5 silicon anode companies for lithium battery
At this stage, the specific capacity of commercial graphite anode materials is close to the theoretical limit, and there is little room for improvement.
As the market’s requirements for the cruising range of electric vehicles continue to increase, it is necessary to develop new anode materials with higher gram capacity and increase the energy density of lithium batteries.
Due to its extremely high energy density, silicon anode materials can achieve high capacity and long service life through modification, and they are expected to become the mainstream direction of research and development of anode materials for next-generation high-energy-density lithium batteries.
Global top 5 silicon anode companies
Due to the improvement of battery life requirements for electric vehicles, lithium batteries anode materials need to be developed in the direction of high specific capacity. As the key to improving the energy density of the next-generation electric vehicle power battery, the silicon anode material has become an ideal material breakthrough point for power battery upgrades.
The huge future market development and profit potential contained in the extremely low market penetration rate of silicon-based anode materials will promote silicon anode companies to accelerate their strategic layout.
