It is believed that poly (vinylene carbonate) based electrolyte formance of lithium ion batteries to some [5,6] can be a very promising solid polymer electrolyte candidate for high energy extent, the existence of liquid electrolyte always is closely related to a hidden safety density lithium batteries. hazard. The solid electrolyte is a key com- ponent for ensuring high safety and high voltage window. Among solid state electro- lytes, solid polymer electrolyte takes the advantage of high flex- ibility, easy processability, and low interfacial resistance when compared with inorganic ceramic electrolyte.[7] These merits Dr. J.
