Abstract

The role of inorganic ceramic fillers namely nanosized A12O3 (15-25 nm) and TiO2 (10-14 nm and ferroelectric filler SrBi4Ti4O15 (SBTCIT) (0.5 m) synthesized by citrate gel technique (CIT) on the ionic conductivity and electrochemical properties of polymer blend 15 wt% PMMA+PEO8:LiC1O4 + 2 wt% EC/PC electrolytes were investigated. Enhancement in conductivity was obtained with a maximum of 0.72 x 10-5 S cm-1 at 21C for 2 wt% of SrBi4Ti4O15 (SBT CIT) composite polymer electrolyte. The lithium-ion transport number and the electrochemical stability of the composite polymer electrolytes at ambient temperature were analysed. An enhancement in electrochemical stability was observed for polymer composites containing 2 wt% if SrBi4Ti4O15 (SBT CIT) as fillers.
