As experts in chemical synthesis, we have developed Electrosperse™ 4000, a polymeric amide dispersant designed to form concentrated carbon dispersions (slurries) in NMP (N-Methyl-2-pyrrolidone), the industry standard solvent used to manufacture battery electrodes. Electrosperse™ 4000 improves the distribution uniformity of conductive carbon particles in electrodes. This enhances capacity retention at high carge-discharge rates.
Dispersants are used in various stages of the lithium-ion battery manufacturing process to optimize the viscosity of processing slurries, making it easier to handle and speed up processing time, and to increase the distribution of conductive carbon in electrodes. This leads to improved capacity retention and electro-chemical stability.
