Description
This hard carbon anode material is produced from renewable biomass raw materials through a proprietary process. Its internal pore structure and disordered carbon layer distribution are rationally optimized, effectively enhancing sodium/lithium ion storage capacity. The product combines high specific capacity with excellent initial efficiency, maintaining stable output under medium-to-high rate charge-discharge conditions and exhibiting good power response characteristics.
Furthermore, its excellent processability facilitates electrode coating and mass production, meeting the application requirements that strike a balance between cost and performance.
This material is particularly suitable for small power batteries and two-wheeled vehicles, providing a reliable anode material option for lightweight and economical power systems.
