To find out the proper sodium ion conducting electrolyte at room temperature, we investigated the ac impedance measurement of PVdF gel polymer electrolyte and liquid tetraglyme(TEGDME) with various concentrations of sodium trifluoromethane sulfonate(NaCF3SO3). The concentration of NaCF3SO3 did not severely affect the ionic conductivity. The sodium ionic conductivity using TEGDME with NaCF3SO3 was about 3.3×10-4 S㎝-1 which was lower than that of the PVdF gel polymer electrolyte, 5.0×10-4 S㎝-1. From the viewpoint of ionic conductivity, PVdF gel polymer electrolyte was proper electrolyte for sodium battery.
