Composite polymer electrolytes(CPEs) containing inorganic nanofiller are reported in this report. For CPE preparation, polymer blend of poly(ethylene oxide)(PEO) with poly(acrylonitrile)(PAN), mixed with nano-Al2O3, is used as polymer matrix, namely PEO-PAN-Al2O3. The performance of the PEO-PAN-Al2O3 is observed by AC impedance, DSC, SEM image. The ionic conductivity of the CPEs was measured by AC impedance, and the crystallinity of the CPEs was evaluated by using DSC, and the morphology of the CPEs was observed by SEM image. It was found that the nano-Al2O3 can effectively improve Li ion behavior and ionic conductivity of composite polymer electrolytes. |
