Abstract : Different ratios of bismuth ferrite (BiFeO3) nanoceramic doped with cellulose acetate-lithium chloride (CA:LiCl) polymer electrolytes were successfully prepared using solution cast method. All samples were characterized by attenuated total reflectance-Fourier transform Infrared (ATR-FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), impedance spectroscopy (EIS). The complex permittivity, ξ* and electric modulus, Μ* have been analysed. Highest ionic conductivity obtained is 2.34 x 10-4 S cm-1 by employing 0.5 wt % BiFeO3 nanoceramic in CA:LiCl polymer electrolyte system. Surface morphology of CA:LiCl: BiFeO3 film showed molecule closely packed structure which enable the increment of the conductivity and in association with the enhancement of complexation between Li+ ion and CA as resulted from ATR-FTIR and XRD.
