“…Solid electrolytes are characterized by high polarizability and high values of permittivity. As a result, the energy of short-range Van der Waals interaction is comparable to the energy of Coulomb interaction [4][5][6][7][8]. To address this fact, we combine two methods that had previously been used to describe systems of neutral and charged particles, namely the methods used in [23,[29][30][31][32][33] with the collective variables approach capable of taking into account long-range interactions [20,21].…”

“…They are widely used in electrochemical sensors, rechargeable batteries, supercapacitors, memory devices, fuel cells and other technological applications [1][2][3]. These materials are characterized by high defect crystal structure and inhomogeneities inducing the emergence of electrical double layers close to intergrain boundaries [4][5][6][7][8].…”

“…This fact allows us to apply the adiabatic approximation and reduce the problem to a one-component model. In the framework of this description, we consider thermal movement of cations against a homogeneous negatively charged background of fixed anions confined by the crystal lattice [1][2][3][4][5][6][7][8]. To this end, we apply a cell model in the framework of lattice description whereby we consider only the case of cation leaps between lattice sites.…”

A solid ionic conductor with cation conductivity in the interelectrode region is studied. Due to their large size, the anions are considered fixed and form a homogeneous neutralizing electric background. The model can be used to describe properties of ceramic conductors. For a statistical mechanical description of such systems, which are characterized by short-range Van der Waals interactions and long-range Coulomb interactions, an approach combining the collective variables method and the method of mean cell potentials is used. This formalism was applied in our previous work [Bokun G., Kravtsiv I., Holovko M., Vikhrenko V., di Caprio D., Condens. Matter Phys., 2019, 29, 3351] to a homogeneous state and in the present work is extended to an inhomogeneous case induced by an external electric field. As a result, mean cell potentials become functionals of the density field and can be described by a closed system of integral equations. We investigate the solution of this problem in the lattice approximation and study charge and electric field distributions in the interelectrode region as functions of plate electrode charges. The differential electric capacitance is subsequently calculated and discussed.
