We use a classical density functional theory (DFT) to study the electric double layer formed by charged hard spheres near a planar charged surface. The DFT predictions are found to be in good agreement with recent computer simulation results. We study the capacitance of the charged hard-sphere system at a range of densities and surface charges and find that… (More)

The effect of anisotropic ion shapes on the structure and the differential capacitance of an electric double layer in the electrolyte solution regime is studied using the density functional theory and Monte Carlo simulations. The double layer is modelled by a uniformly charged, non-polarizable planar electrode next to an electrolyte where the cation is a… (More)

Theoretical difficulties in describing the structure and thermodynamics of an ionic liquid double layer are often associated with the nonspherical shapes of ionic particles and extremely strong electrostatic interactions. The recent density functional theory predictions for the electrochemical properties of the double layer formed by a model ionic liquid… (More)

The differential capacitance curve for the double layer formed by an electrolyte dissolved in a solvent is commonly believed to be parabolic-like with a minimum at low electrolyte charge concentration and low electrode surface charge density, and independent of electrolyte concentration at high electrolyte concentrations and high electrode charge and would… (More)

The planar electric double layer capacitance of the solvent primitive model electrolyte is studied using simulation and two versions of the modified Poisson-Boltzmann theory. At small values of the surface charge and varying electrolyte concentration, the capacitance has a behaviour analogous to that of the restricted primitive model electrolyte. As the… (More)

Monte Carlo (MC) simulation and classical density functional theory (DFT) results are reported for the structural and electrostatic properties of a planar electric double layer containing ions having highly asymmetric diameters or valencies under extreme concentration condition. In the applied DFT, for the excess free energy contribution due to the hard… (More)

Results of the Monte Carlo simulation of the electrode/molten salt interface are reported. The system investigated was modeled by the restricted primitive model of electrolyte being in contact with the charged hard wall (hard spheres of diameter d=400 pm and relative permittivity epsilon(r)=10). The temperature analysis of the mean activity coefficient… (More)

The structure of a planar electric double layer formed by a 2:2 valency dimer electrolyte in the vicinity of a uniformly charged planar hard electrode is investigated using density functional theory and Monte Carlo simulations. The dimer electrolyte consists of a mixture of charged divalent dimers and charged divalent monomers in a dielectric continuum. A… (More)

Results of the Monte Carlo simulation of the electrode | molten salt or ionic liquid interface are reported. The system investigated is approximated by the primitive model of electrolyte being in contact with a charged hard wall. Ions differ in charges, namely anions are divalent and cations are monovalent but they are of the same diameter d = 400 pm. The… (More)

Monte-Carlo simulations of the electric double layer are performed for two electrolyte mixtures next to a plane, uniformly charged, surface. Simulations are made at parameters corresponding to a Poisson-Boltzmann theory which is corrected to include the excluded volume effects of the ions. The corrected Poisson-Boltzmann theory is found to have some… (More)
