CONDUCTING SALTS FOR GALVANIC CELLS, THE PRODUCTION THEREOF AND THEIR USE

摘要

The invention relates to a conducting salt which contains lithium bis(oxalato)borate (LiBOB) and mixed lithium borate salts of the type of formula (I), wherein the portion of compound (I) in the conducting salt is 0.01 to 20 mole- % and X in formula (I) is a bridge linked with the boron via two oxygen atoms, selected from formula (II), wherein Y<1> and Y<2 >together = O, m = 1, n = 0 and Y<3 >and Y<4 >independently represent H or an alkyl group with 1 to 5 C atoms, or Y<1>, Y<2>,< >Y<3>, Y<4>, independently represent OR (with R = alkyl group with 1 to 5 C atoms), or H or an alkyl group with 1 to 5 C atoms, and wherein m = 0 or 1, n = 0 or 1, or Y<2> and Y<3 >are members of a 5-or 6-membered aromatic or heteroaromatic ring (with N, O or S as the hetero element) which can be optionally substituted with alkyl, alkoxy, carboxy or nitrile, and if so, Y<1> and Y<4 >are not applicable and n = 0, m = 0 or 1.
