On the characteristics of electrolytes with new lithium imide salts
In our continuous study on organic lithium salts, we found that the imide salt (RfSO(2)) (R'fSO(2))NLi shows high conductivity in organic solvents, and that the modification of the imide salts change the anodic oxidation potential and the dissolution potential of aluminum current collector. Lithium imide with long fluoroalkyl groups such as (C4F9SO2) (CF3SO2)NLi and the new ester-type imide salts, ((CF3)(2)CHOSO2)(2)NLi do not dissolve the aluminum collector up to 4.8 and 4.3 V, respectively. We also examined the polymer analogue of the ester-type imide salt such as (-CH2(CF2)(4)CH2OSO2N(Li)SO2O-)(9-10).
