General theory of asymmetric steric interactions in electrostatic double layers
General theory of asymmetric steric interactions in electrostatic double layers
We study the mean-field Poisson–Boltzmann equation in the context of dense ionic liquids where steric effects become important. We generalise lattice gas theory by introducing a Flory–Huggins entropy for ions of differing volumes and then compare the effective free energy density to other existing lattice gas approximations, not based on …
