Thermal and electrical conducting property of sodium polymer electrolyte containing barium titanate filler

Composite polymer electrolyte of sodium perchlorates (NaClO4)-poly ethylene oxide (PEO) containing a different of barium titanate (BaTiO3) were synthesized by solution casting method. The addition of (BaTiO3) filler to the PEO-NaClO4 electrolyte further increase ionic conductivity. The 5 wt% BaTiO3 contained composite electrolyte offer a maximum ionic conductivity, which is ∼1.0×10-5 S/cm. FTIR results revealed the interaction polymer chain-salt complexes. DSC studies demonstrated that effect of crystallinity reduction by added BaTiO3 filler.
