Supplemental Information for: A kinetic model to simulate charge flow through an electrochemical half-cell

The Supplementary Material (SM) document contains a discussion of the diffusion properties of ions in a fluid medium; details on the computational determination of thermodynamic and electrostatic properties from the simulation raw data; a discussion of the contact density and active particles' density on the scaled surface charge density $\sigma^{\ast}$; the empirical verification of the low dependence of the radial current density on the radius of the spherical sample.
