Every year demand increases, cost of lithium resource is increasing exponentially. It is hold great influence throughout the world. the search for alternative of lithium ion system is essential. Sodium ion technology is most promising among the alternatives. because of sodium resources are the easy availability of everywhere around the world. In this study, we synthesized poly(ethylene oxide)- sodium perchlorate (NaClO4) composite electrolyte containing a different of nano-sized barium titanate(BaTiO3) filler, in order to examine the filler addition effect on the structural modification and electrochemical properties The ionic conductivity value(σ) was calculated from the bulk resistance(Rb), which was determined by equivalent circuit analysis software. The morphology of the film was evaluated by using scanning electron microscope(SEM), and crystallinity was analyzed by differential scanning calorimetry(DSC). |
