Abstract
Official abstract text for this publication.
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 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 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. The invention also relates to a method for producing the inventive conducting salts.
First claim
Opening claim text (preview).
The invention claimed is: 1. A conducting salt comprising lithium bis(oxalato) borate (LiBOB) and a mixed lithium-borate salt of formula (I) wherein the conducting salt is fluorine free; wherein the proportion of the mixed lithium-borate salt of formula (I) in the conducting salt ranges from 0.01 mol. % to 20 mol. %, and wherein…
