| 摘 要： | IntroductionDue to their potential application in lithium-ion secondary batteries1] and other electrochemicaldevices2 ] ,gel polymer electrolytes have attractedmuch interest in recent years.There were manykinds of polymeric materials being developed aspolymeric hosts for gelelectrolytes. Polyvinylidenefluoride( PVDF) is one of three kinds of matrixthat can be commercially applied3 ,4] ,and the oth-ers are polyacrylonitrile ( PAN) and poly( methylmethacrylate) ( PMMA) .There were many r…

| Abstract: | Two series of polyvinylidene fluoride (PVDF) based gel polymer electrolytes, with different LiClO4 or propylene carbonate (PC) content, were prepared and analyzed by infrared spectrometer, differential scanning calorimetry, scanning electron microscope and complex impedance spectrometer. The results show that there are great interactions between PVDF, PC and lithium cations. Both LiClO4 and PC content lead to evident change of the morphology of the gel polymer electrolytes. The content of LiClO4 and PC also influences the ionic conductivity of the samples,and an ionic conductivity of above 10-3S·cm-1 can be reached at room temperature. |
