During the last years the term “Negative Capacitance" (NC) has appeared in the literature. Until now there is not a satisfactory theory to explain NC. However, in this paper we develop a new method to calculate ionic mobility by using a simple quantitative model linked with the NC phenomenon. The other aim of this paper is to confirm the validity of our previous hypothesis about the origin of NC, and hence to contribute to a better understanding of the NC phenomenon.
