摘要：

Nanocomposite polymer electrolyte consisting of polyvinyl alcohol (PVA) and lithium acetate with TiO2 filler has been synthesised by combination of solution cast technique and sol-gel process. The composite electrolyte films were characterised by different experimental techniques. The average particle size of composite electrolytes lies between 25 and 30 nm. System is essentially ionic with maximum conductivity of polymer electrolyte 90[80PVA-20LiAc]:10TiO(2) (similar to 4.5 x 10(-6) S cm(-1)) at room temperature.
