| 摘要 |
The invention can relate to lithium salts of the general formula (I) <paragraph lvl="0"><in-line-formula>Li[P(OR1)a(OR2)b(OR3)c(OR4)dFe] (I) </in-line-formula>where 0<a+b+c+d<=5 and a+b+c+d+e=6 and R1 to R4 are, independently of one another, alkyl, aryl or heteroaryl radicals, where at least two of R1 to R4 may be directly bound to one another by a single or double bond, with the exception of lithium perfluoropinacolyltetrafluorophosphonate(V). The lithium salts used according to the invention can have high oxidation potentials and may be suitable for nonaqueous electrolytes in electrochemical cells, in particular lithium ion batteries, having a high electrochemical stability.
