Abstract: In this paper, the ionic conductivity of the BM350-LiClO4 complexes was studied as a function of temperature and salt concentration.At high salt concentrations, the more pronounced fall in conductivity in the solid medium has been interpreted as being due to the effect of Tg and bulk viscosity on ion transport. Conductivities which displayed non-Arrhe-nius behviour were analysed using the Vogel-Tammann-Fulcher equation and interpreted on the basis of the configurational entropy model derived by Gibbs and coworkers.
