Abstrakt: Composite polymer electrolytes (CPEs) consisting of poly(vinyl alcohol) (PVA), lithium triflate (LiTf), and with various percentage of weight (wt.%) of titanium (IV) oxide (TiO2) filler have been prepared by solution casting technique. CPE with 6 wt.% of TiO2 fillers achieved the highest ionic conductivity of (3.45±0.01)×10−4 S cm−1 at ambient temperature. Differential Scanning Calorimetry (DSC) study does not show a significant change in glass transition temperature (Tg) upon addition of TiO2 fillers. Linear sweep voltammogram shows a wider potential window of the most conducting filler-added polymer electrolyte compared to the filler-free polymer electrolyte. [ABSTRACT FROM AUTHOR]
