The invention relates to conducting salts which contain 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 Yand Ytogether=O, m=1, n=0 and Yand Yindependently represent H or an alkyl group with 1 to 5 C atoms, or Y, Y, Y, Yindependently represent OR (with R=alkyl group with 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 Yand Yare 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, Yand Yare not applicable and n&#x3e;0, m=0 or 1. The invention also relates to a method for producing the inventive conducting salts.
