Black Silicon Carbon Composite Material Lithium Ion Battery Anode Materials Battery Si C Anode Raw
Product Description:
This a kind of hard carbon prepared from plant raw materials. It has excellent performance in low temperature, rate, cycle and safety. It is widely used in power battery, power supply, sodium ion battery and so on.
As a new anode energy material, Nano Silicon Crabon anode material has ultra-high theoretical specific capacity and low lithium removal potential(<0.5v), and the voltage platform of silicon is slightly higher than that of graphite, so it is difficult to cause lithium dissection on the surface during charging, and the safety performance is better.
The product is characterized with high capacity(≥400Ah/g), high first efficiency(≥85%), good cycle performance, low volume expansion and realization the SNNC and non crystalline of Si. It is widely applied for 3C digital, power tools, electric vehicles (EV/HEV/PHEV).
