PP13PF6 (1-Methyl-1-Propylpiperidinium hexafluorophosphate, >99.9%) Ionic Liquid as Battery Electrolyte Solvent, 25-100 g/bottle, CBESPP13PF6

PP13PF6 (1-Methyl-1-propylpiperidinium hexafluorophosphate) is an ionic liquid that combines an aliphatic, 6-membered piperidinium cation with the phosphorus-based hexafluorophosphate (PF6^-) anion. By pairing the highly reduction-resistant piperidinium ring with a PF6^- anion, this formulation attempts to merge the robust cathodic stability of saturated cyclic ammonium cations with the structural familiarity of PF6^- salts commonly used in conventional lithium-ion batteries. However, its deployment as a battery electrolyte solvent brings specific chemical trade-offs.

The key physicochemical characteristics of PP13PF6 are: (1) High Cathodic Stability: Unlike aromatic cations (such as imidazolium in EMIMPF6), the saturated 6-membered piperidinium ring (PP13) exhibits excellent resistance against reduction. This makes it significantly more compatible with carbonaceous anodes or high-voltage reductive environments. (2) Thermal Safety & Non-Volatility: Like other ionic liquids, PP13PF6 is non-flammable, has negligible vapor pressure, and maintains high thermal stability, effectively eliminating the volatile fire risks tied to organic carbonate blends.
