Abstract (en)

[origin: DE19733948A1] The invention concerns compounds of formula (I): M2[R1-SO2-(CF2)n-SO2-R], in which R and R1 independently represent C(SO2RF)2, N(SO2RF) or O (R) and C(SO2RF)2 or N(SO2RF) (R1); RF stands for (CxF2x+1); M stands for a counterion from the group composed of Li, Na, K, Cs, Rb, B1/2 and Mg1/2, Sr1/2, Ba1/2; n equals 1, 2 or 3; and x equals 1, 2, 3 or 4. Also disclosed are processes for preparing the same, their use in electrolyte systems as conducting salts in lithium batteries, as well as electrolytes for lithium batteries containing compounds of general formula (I), but also secondary lithium batteries per se which contain corresponding electrolytes.
