Battery-Grade Binders: Hydrophilic, SBR and PVDF

Targray supplies battery-grade binders used in the slurry making process for Lithium-ion batteries. Specialty binder powder formulations such as Hydrophilic, SBR and PVDF are used in Lithium-ion battery technology to hold the active material particles together and in contact with the current collectors i.e. the Aluminium Foil (Al foil) or the Copper Foil (Cu foil).

Battery-Grade Binder Formulas

Given the intricate nature of the manufacturing steps outlined above, the binder powder formula’s characteristics are highly significant and must conform to strict criteria. Primary characteristics of relevance are:

  • Ionic Conductivity
  • Tensile Strength
  • Water Absorption
  • Adhesion Property
  • Swelling in Electrolyte
  • Melting point
  • Molecular weight distribution
  • Dissolution properties
  • Crystalline properties
  • Purity

Working with supply partners and organizations including the Electrochemical Society and NAATBatt International, we help lithium-ion battery manufacturers and researchers worldwide commercialize ambitious new technologies for the energy storage market.
