Abstract
A novel polymer electrolyte was prepared by employing poly(ethyleneglycol) (PEG)-borate ester as plasticizer to the electrolyte composed of poly(ethyl eneglycol) methacrylate (PEGMA) and lithium bis-trifluorumethanesulfonimide (LiTFSI). The PEG-berate ester shows good thermal stability and high hash point. The ionic conductivity of the polymer electrolyte increases with inc reasing amount of the PEG-berate eater and exhibits greater value than 10(- 4) S cm(-1) at 30 degreesC and 10(-3) S cm(-1) at 60 degreesC.
