A new type of lithium salts, —SO 2 NLiSO 2 OCH 2 (CF 2 ) n CH 2 O m — (LiPPFASI, where n = 2, 3, 4, 6, and 7), was used as salts in poly(ethylene oxide) (PEO)‐based solvent‐free electrolytes. The conductivity and electrochemical stability behaviors were studied. The results showed the electrolytes almost have a similar conductivity and the PEO–LiPPFASI ( n = 3, EO/Li = 10) was the relatively better system under the experiment conditions. Moreover, most systems were found to be oxidatively stable up to 5.5 V versus Li/Li + and the lithium deposition‐stripping process on the electrode was reversible for all the polymer electrolytes. © 2001 John Wiley & Sons, Inc.
