초록

The purpose of this study is to research and develop solid polymer electrolyte(SPE) for Li secondary battery. This paper describes effects of plasticizer addition and temperature dependence of conductivity of these PEO electrolytes. Adding propylene carbonate and ethylene carbonate to PEO-LiClO$_4$electrolyte, its conductivity was higher than PEO-LiClO$_4$ itself. Steady state current method and AC impedance used for the determination of transference number in PEO electrolyte film. The transference number of PEO$\_$8/LiClO$_4$PC$\_$5/EC$\_$5/ polymer electrolyte film is 0.45 at 60$^{\circ}C$.
