In-situ UV cured acrylonitrile grafted epoxidized natural rubber (ACN-g-ENR)-LiTFSI solid polymer electrolytes for lithium-ion rechargeable batteries

Solid polymer electrolytes (SPEs) of newly synthesized acrylonitrile grafted epoxidized natural rubber (ACN-gENR) were successfully prepared with lithium bis(trifluoromethanesulfonyl)imide salt (LiTFSI) via UV curing technique. The highest ionic conductivity of the SPEs was accomplished at 40 wt% Li...
