Lithium-ion battery is the advantage of longer life, high energy density and open circuit voltage. In order to have a good solid polymer electrolyte, Ion Transference number must be high One way to increase the transfection number is to fix the anion to the polymer structure and fix the lithium cation. Therefore, our present work is to synthesize solid polymer electrolyte based on fluorosulfonyl group by fixing anion to polymer structure. Synthesis of monomer with Fluorosulfonylimide groups was synthesized from Fluorosulfonyl isocyanate and maleimide materials. In this process, the reaction was carried out by using Triethylamine (TEA) as a base catalyst, because the reaction was not carried out without catalyst. Polymerization was carried out using radical initiator as benzoyl peroxide. The Copolymer was synthesized with Fluoromalesulfoneimide, methyl methacrylate and styrene monomer. The synthesized polymer will be studied 1H-NMR. The polymer thermal property will be analyzed by TGA.
