Abstract

The invention relates to an electrolyte composition containing at least one compound of (I) wherein R1 is selected from C1 to C10 alkyl, and R2 is selected from O(C1 to C10 alkyl), OC(O)(C1 to C10 alkyl), OC(O)O(C1 to C10 alkyl), OS(O)2(C1 to C10 alkyl) and S(O)2O(C1 to C10 alkyl), wherein C1 to C10 alkyl may be substituted by one or more F and wherein one or more CH2— groups of C1 to C10 alkyl which are not bound directly to O may be replaced by O.
