A single-ion gel polymer electrolyte based on polyimide grafted with lithium 3-chloropropanesulfonyl (trifluoromethanesulfonyl) imide for high performance lithium ion batteries

A polyimide-based single-ion polymer PI-LiCPSI was prepared. PI-SIGPE obtained by compounding of PI-LiCPSI and PVDF-HFP showed good mechanical properties due to the rigid frame and strong interface, and also possessed excellent electrochemical and cycling performance.
