This composite conductive paste is developed for lithium iron phosphate batteries. It combines graphene, carbon black, carbon nanotubes, and NMP solvent and is produced using a multi-stage continuous nano-dispersion technology on an automated production line. This ensures uniform dispersion and consistent quality. The product leverages graphene's superior electrical and thermal conductivity, carbon black's liquid retention and low-cost characteristics, and the collaborative effect of carbon nanotubes, forming an efficient three-dimensional conductive network on the anode material, reducing internal resistance and costs while enhancing rate performance and cycle life.
