Halide-Free Synthesis of New Difluoro(oxalato)borate [DFOB]^- -Based Ionic Liquids and Organic Ionic Plastic Crystals.

ABSTRACT: The implementation of next-generation batteries requires the development of safe, compatible electrolytes that are stable and do not cause safety problems. The difluoro(oxalato)borate ([DFOB]^- ) anion has been used as an electrolyte additive to aid with stability, but such an approach has most commonly been carried out using flammable solvent electrolytes. As an alternative approach, utilisation of the [DFOB]^- anion to make ionic liquids (ILs) or Organic Ionic Plastic Crystals (OIPCs) allows the advantageous properties of ILs or OIPCs, such as higher thermal stability and non-volatility, combined with the benefits of the [DFOB]^- anion. Here, we report the synthesis of new [DFOB]^- -based ILs paired with triethylmethylphosphonium [P₁₂₂₂
