摘要：
The equations used to describe the diffuse double layer in the Eigen-Wicke model of ionic liquids are presented. They are then used to estimate the potential drop across the diffuse layer and its differential capacity for two representative systems which contain monovalent ions of equal diameter. The first one is molten RbCl at 750 degrees C. The second system is a room temperature ionic liquid with typical parameters to describe its properties. The results of the calculations are compared with the available experimental data. It is concluded that the Eigen-Wicke model does not consider the change in local potential experienced by a given ion in the ionic liquid. The need for Monte Carlo data for the diffuse double layer in molten salt systems is emphasized.
