Solid polymer electrolyte with PVdF polymer and LiBOB salt has been prepared with doctor blade method. To improve the membrane ionic conductivity, TiO2 has been added. Surface morphology analysis was performed using SEM and EDX spectroscopy. Conductivity behaviour was studied with AC impedance spectroscopy (EIS). SEM and EDX analysis results have shown that TiO2 addition played a role in pore formation on solid polymer electrolyte membrane. The highest value of ionic conductivity in PVdF-LiBOB solid polymer electrolyte system in this research was found to be 5.79% x 10-6 Scm-1 in room temperature, i.e sample with 30% TiO2 addition. It was also studied that agglomeration of TiO2 particle occurred on the surface of the membrane resulted in decreasing of ionic conductivity.
