摘要：

Poly(ionic liquid)s combine the unique properties of ionic liquids (ILs) within ionic polymers holding significant promise for energy storage applications. It is reported here the synthesis and characterization of a new family of poly(ionic liquid)s synthesized from cationic piperazinium ionic liquid monomers. The cationic poly(acrylamide piperazinium) in combination with sulfonamide anions like bis(trifluoromethanesulfonyl) imide (TFSI) and bis(fluorosulfonyl) imide (FSI) are characterized as solid polymer electrolytes. The polymer electrolytes in combination with pyrrolidonium ILs and LiFSI show high ionic conductivity, 5x10-3 S cm-1 at 100 degrees C. Piperazinium polymer electrolytes show excellent compatibility with lithium metal reversible plating and stripping at high current density and low temperature 40 degrees C. It is reported here the synthesis and characterization of a new family of poly(ionic liquid)s based on cationic piperazinium ionic liquid monomers with sulfonamide anions, like TFSI and FSI, employed as solid polymer electrolytes in combination with pyrrolidonium ILs and LiFSI for lithium battery application with excellent compatibility of Li metal reversible plating and stripping at high current density and low temperature. image
