| Abstract | A new ternary polymer electrolyte based on thermally cross-linked poly(urethane acrylate) (PUA), lithium bis(trifluoromethansulfonyl)imide (LiTFSI) and the ionic liquid N-butyl-N-methylpyrrolidinium TFSI (PYR14TFSI) was developed and tested for application in LMP batteries. The polymer electrolyte was a transparent yellow self-standing material with quite good mechanical properties, i.e., comparable to that of a flexible rubber. The room temperature ionic conductivity of the dry polymer electrolyte was found to be as high as 0.1 mS cm-1 for the compound containing 40 wt% of ionic liquid (PYR14TFSI) and a O/Li ratio of 15/1 (Li+ from LiTFSI). The thermal analysis of the new cross-linked electrolyte showed that it was homogeneous, amorphous and stable over a wide temperature range extending from -40 °C to 100 °C. The homogeneity of the polymer electrolyte was also confirmed by SEM analysis. © 2008 Elsevier Ltd. All rights reserved. |
