Description |
Magnesium aluminate (MgAl2O4)-incorporated poly(ethylene oxide) (PEO)–lithium hexafluorophosphate
(LiPF6) based composite polymer electrolyte (CPE) membranes were prepared by a hot press for
the first time. The membranes were subjected to X-ray diffraction (XRD), scanning electron microscopy
(SEM), thermogravimetric (TG), differential scanning calorimetry (DSC), tensile, impedance spectroscopy,
compatibility and transport number studies. The incorporation of MgAl2O4 greatly enhanced the ionic
conductivity, compatibility and mechanical integrity of the polymeric membrane. Finally, an all solid state
lithium cell composed of Li/CPE/LiFePO4 was assembled and its cycling profile was analyzed at 70 ◦C. The
cells delivered a discharge capacity of 127 mAh g−1 at 1 C-rate with very good capacity retention up to
100 cycles which is found to be better than those reported earlier
