Abstract
A hybrid, poly(vinylidenefluoride-co-hexafluoropropylene) P(VdF-HFP)/MgO-based pristine composite polymer electrolyte (PCPE) and composite microporous polymer electrolyte (CMPE) have been prepared successfully by polymer dissolution method. Different morphology of the composite membrane was examined by field emission scanning electron microscopy. The conductivity of the PVP extracted CMPE is higher than that of optimized filler (8 wt% MgO) incorporated PCPE. It proved good compatibility with lithium electrodes, and an electrochemical stability window spanning the range of 0.0 to 5.0 V vs. Li/Li+. The performance of CMPE is relatively high and stable when compared with PCPE for rechargeable lithium-ion polymer batteries.
