Electrosperse™ 4000 is a polymeric amide dispersant designed to form concentrated carbon dispersions in N-Methyl-2-pyrrolidone (NMP), which are used to manufacture battery electrodes.​

Electrosperse™ 4000 polymer helps disperse conductive carbon more uniformly on electrode materials to improve capacity and protect the battery from degradation during charge and discharge events. It is especially effective at high C-rates.

Applications:

  • Battery technologies
