Features

JEFFSOL® MEOX can efficiently dissolve binders including PVDF, aids in carbon or conductive additive dispersion stability, and can be used to safely cast cathodes for lithium-ion batteries. It is a suitable alternative to NMP in battery manufacturing process and computational modeling has demonstrated compatibility with existing manufacturing processes including solvent recovery.

Benefits

  • High polarity aprotic solvent
  • Low vapor pressure and low odor
  • Not rated as hazardous air pollutant
  • Less hygroscopic than NMP
  • High flash point, nonflammable
  • Excellent solvency of PVDF for NMC and LFP cathodes
  • Comparable rheology in NMC/PVDF slurries to NMP
  • Good compatibility with aluminum
  • Ease of condensation may reduce energy and complexity in recovery systems
