Abstract

Anomalies in the double layer properties of electrolytes with strong ionic interactions have been observed in recent simulations. As yet these anomalies have not been predicted by any theory. The anomalous temperature dependence of the capacitance has been observed experimentally. In this note the generalized mean spherical approximation (GMSA) is applied to the electrochemical interface. In contrast to other theories, the GMSA predicts, in agreement with simulations, partial drying and an adsorption isotherm that is negative and large in magnitude. The anomalous behavior of the capacitance remains unexplained.
