Tetrakisfluoroalkylborate salts (I) are new. Tetrakisfluoroalkylborate salts of formula (I) are new: Mn+((BR4)<->)n (I) Mn+ = mono, di- or trivalent cation; R = (CxF2x+1); x = 1-8; and n = 1-3. Independent claims are also included for: (1) a process for the production of a tetrakisfluoroalkylborate salt (I) comprising reaction of a salt of formula (II) with a fluorinating agent in a solvent followed by purification and separation by conventional means; (2) a mixture comprising a salt (I) and at least one polymer; (3) a process for the production of the mixture comprising mixing the salt (I) and at least one polymer, optionally with a solvent; (4) an electrolyte primary battery, secondary battery, capacitor, super capacitor or galvanic cell containing the tetrakisfluoroalkyl borate salt (I).
