摘要：
The present study focuses on the preparation and characterization of poly(vinyl alcohol)/poly(vinylidene fluoride) blend polymer electrolyte doped with lithium triflate (LiCF3SO3). Interaction of lithium triflate with the host polymer in the solid polymer electrolyte was studied using X-ray diffraction, Fourier transform infrared spectroscopy and differential scanning calorimetry analysis. It was found that 15% salt doped polymer electrolyte possesses the highest ionic conductivity (2.7 x 10(-3) S/cm) at 303 K, the higher thermal stability at 175A degrees C. Linear sweep voltammetry results revealed that the film is electrochemically stable up to 3.4 V.
