WebNov 1, 2013 · We further demonstrate that the Lewis base additive dimethyl acetamide (DMAc) can enhance the stability of LiPF6 -based organosilicon electrolyte. Our results demonstrate that the stability of 1NM3 is limited by decomposition of the salt and demonstrate the mechanism by which the organosilicon compound decomposes. WebWhen LiTFSI was added, the ionic conductivity was enhanced and was optimized at 30 wt. % of LiTFSI with value of 3.54 x 10-5 Scm-1. Further enhancement of the ionic conductivity occurred when 8 wt. % of EMImTFSI was added into the polymer electrolyte system with value of 1.15 x 10-4 Scm-1. The increase in ionic conductivity is due to increasing
