Electrochemical supercapacitors feature relatively higher energy densities than conventional capacitors. With several advantages, such as fast charging, long charge–discharge cycles, and broad operating temperature ranges, electrochemical supercapacitors have found wide applications in hybrid electric vehicles.

This 1D tutorial models the current distribution and electrode utilization in the porous electrodes in an electrochemical capacitor. The Nernst-Planck equations are used to model transport by diffusion and migration of the binary electrolyte, using tortuosity and porosity parameters to derive effective transport parameters for the porous electrodes.

Simulations are run using constant current-constant voltage and constant power charge/discharge loads.
