摘要：

Ionic conductivity of alpha-Li2SO4 with up to 4 mol% Li2WO4 has been measured using quartz capillary U-tubes and complex impedance technique. A significant drop in conductivity and increase in activation energy is observed for 2, 2.5, 3 and 3.5 mol% Li2WO4 compositions while 4 mol% Li2WO4 composition shows an increased conductivity. Based on a recent phase diagram of the binary system, the results are interpreted as convincing evidence for the "Paddle Wheel" mechanism of ion transport in alpha-Li2SO4.
