Graphene/Carbon Black/Carbon Nanotube Composite Conductive Paste
The graphene/carbon black/carbon nanotube composite conductive paste primarily consists of graphene, carbon black, carbon nanotubes, and NMP solvent. It is produced using a multi-stage continuous nano-dispersion technology on an automated production line, ensuring the uniform dispersion and consistent quality of graphene, carbon black, and carbon nanotubes. This product is specifically developed for lithium iron phosphate (LiFePO4) batteries, effectively utilizing the excellent conductivity and thermal conductivity of graphene, the liquid retention capacity and low cost of carbon black, and the synergistic properties of carbon nanotubes. This combination creates an efficient conductive network on the cathode material, reducing the internal resistance and cost of lithium batteries while improving their rate performance and cycle life.
