Mixture used in electrolytes, primary batteries, secondary batteries, capacitors, super capacitors and galvanic cells, contains a fluoroalkylphosphate salt and a polymer. Mixture contains a fluoroalkylphosphate salt of formula: Mn+((PFx(CyF2y+1-zHz)6-x)<->)n (where Mn+ = a monovalent, divalent or trivalent cation; x = 1-; y = 1-8; z = 2y + 1; n = 1, 2 or 3; and the ligands (CyF2y+1-zHz); and a polymer. An Independent claim is also included for the production of the mixture by mixing the fluoroalkylphosphate salt with the polymer and optionally a solvent. Preferred Features: The Mn+ cation is a Li, Na, K, Rb, Cs, Mg or Al cation, preferably a Li cation, or an organic cation, preferably a nitrosyl, nitrile or cation of formula: (NR4)<+>, (P(NR2)k)<+> (where k = 0-4), (C(NR2)3)<+> or (CR3)<+> (where R = H, CoF2o+1-p-qHpAq or A; o = 1-10; p = 0-2o+1; q = 0-2o+1; and A = aromatic residue with optional hetero atoms or a 5 or 6 membered cycloalkyl residue). The fluoroalkylphosphate salt is e.g. of formula: Li<+>(F6-xP(CF2-CF3)x)<-> (where x = 1-3), (N(C2H5)4(PF3(C2F5)3) or (C(N(CH3)2)3)(PF3(C4F9)3). The mixture additionally contains a solvent. |
