The problem in developing solid electrolyte is the interface between solid electrolyte and electrode in an all solid lithium-ion batteries (LIB). Due to this reason, the interfacial properties of solid polymer electrolyte (SPE) for LIB have been studied using scanning electron microscopy (SEM), and electrochemical impedance spectrometry (EIS). The aim of this study is to elucidate the effect of interfacial structure onto the properties of SPE for LIB. Two kind different electrolyte/cathode interfacial arrangements were constructed by coating and stacking Chitosan based SPE onto lithium permanganate based cathode. The effect of interfacial structure onto the impedance has been studied. It was found that in case the SPE stacked on the electrode, micro-gap appeared at the interface and resulted in the existence of Warburg impedance or interfacial resistance. However, when the SPE was coated using solvent casting onto the electrode the micro-gap did not appear and the interfacial resistance could be neglected.
