Negative electrode material
Category：
keyword：Experimental rotary kiln
Description
The advantage of silicon carbon negative electrode materials lies in their extremely high theoretical specific capacity (up to ~4200 mAh/g, far exceeding graphite’s ~372 mAh/g) and excellent energy density ratio. By compounding silicon with carbon matrixes (such as graphene, hard carbon, or porous carbon), they effectively mitigate silicon’s volume expansion (~300%) during lithiation/delithiation cycles while enhancing conductivity.
This unique structural design balances high energy storage and cycle stability, making them one of the most promising and popular materials for the next generation of high-performance lithium battery negative electrodes, especially for power batteries and energy storage systems pursuing longer endurance.
