Abstract

The conductivity of composite solid polymer electrolyte (SPE) made of different compositions of poly(ethylene oxide) (PEO), LiClO4 and fiber was investigated in this study. Results obtained through alternating current (AC) impedance measurements demonstrated that the conductivity of the SPE was much improved by blending fiber into it. Moreover, increasing the composition of fiber added leads, thereby increasing the conductivity of the composite SPE. The average conductivity of the composite SPE was 10-4 S/cm at 25 °C. Performance in thermal properties was also investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) experiments. Although the mechanical strength of the composite SPE was not better than that of other materials as expected, the fiber added made it more stable.
