Product Description

This hard carbon material is prepared from plant raw materials, offering excellent performance in low temperature conditions, rate capability, cycle life, and safety. It is widely used in power batteries, power supplies, and sodium ion batteries.

As a new anode energy material, Nano Silicon Carbon anode material features ultra-high theoretical specific capacity and low lithium removal potential (<0.5v). The voltage platform of silicon is slightly higher than graphite, preventing lithium dissection during charging and improving safety performance.
