Electric double layer on fractal electrodes.
The electric double layer around fractal electrodes is studied with direct numerical simulations of the Nernst-Planck equation coupled with the Poisson equation. The capacitance and the relaxation time obey a power law as a function of the system size, the temperature, and the concentration. The time evolution of the charging process exhibits a stretched exponential law, and the exponent beta is numerically evaluated.
