Abstract

Abstract: In order to achieve highly conductive polymer electrolytes, a room-temperature ionic liquid BMIPF6 was prepared, and the ionic liquid-polymer electrolytes were prepared by the in situ polymerization of MMA in ionic liquid BMIPF₆. DSC analysis and ac impedance measurement revealed that ionic liquid BMIPF₆ could reduce glass transition temperatures, and increase ionic conductivity of the composite ionic liquid\|polymer electrolytes. And the activation energies of ions were calculated according to VTF equation.The composite polymer electrolyte plasticized with BMIPF₆ (50%) exhibited an excellent ionic conductivity up to 0.15 mS/cm. In addition, one of the main advantages of the system was the non-volatility of the components, which had higher decomposition temperatures and was safer than the traditional non-aqueous electrolyte systems including organic solvent.

Key words: Ionic liquid, Poly(methyl methacrylate), Polymer electrolyte, Ionic conductivity
