| titleOfInvention |
Lithium salts, process for preparing them, nonaqueous electrolyte and electrochemical cell |
| abstract |
The invention relates to lithium salts of the general formula (I) Li[P(OR1)a(OR2)b(OR3)c(OR4)d Fe] (I) 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 perfluoro-pinacolyltetrafluorophosphonate(V). The invention also relates to a process for preparing such lithium salts by reacting a phosphorus(V) compound of the general formula (II) P(OR1)a(OR2)b(OR3)c(OR4)d Fe (II) where 0 < a+b+c+d ~ 5 and a+b+c+d+e = 5, and R1 to R4 are as defined above, with lithium fluoride in the presence of an organic solvent. The lithium salts used according to the invention have high oxidation potentials and are suitable for nonaqueous electrolytes in electrochemical cells, in particular lithium ion batteries, having a high electrochemical stability. |
