Boundary Conditions for Electrical Potential

In the solution of electrical potential equations for the electrodes and electrolyte, continuity conditions for electrical potential and current can generally be applied at the interfaces. In the remaining electrolyte surfaces, zero potential gradient or insulation boundary conditions are applied. 

In the solution of electrolyte potential equation with electrode active layer as the boundary, constant ionic current densities and at the anode and cathode active layer boundaries are specified as boundary conditions on the basis of an agglomerate model as
