Carbon Nanotubes-based Conductive Additives for Lithium-Ion Battery
These Carbon Nanotubes-based Conductive Additives are designed to enhance the performance of lithium-ion batteries. The composite contains carbon nanotubes and carbon black, offering high electrical conductivity while maintaining easy dispersion in battery electrodes. Carbon black particles prevent CNTs from reagglomeration, making the material suitable for both anodes and cathodes. Compared with traditional conductive additives, this product significantly improves battery performance, including longer cycle life, higher current capability, improved tap density, and stronger electrodes.
