Use the Thin Additional Porous Electrode Material boundary node from the Electrolyte submenu to define an additional porous electrode material on a thin porous electrode boundary. The feature can only be applied to boundaries that contain an active Thin Porous Electrode node.

The settings in this section specify the volume fraction of the additional porous electrode material.

By selecting Intercalating particles, the node adds a mass balance and the corresponding dependent variables for solving for an intercalating concentration. The settings related to the intercalation are set on the Particle Intercalation child node.

See the Additional Porous Electrode Material node for a description of the remaining settings of this node. A Porous Electrode Reaction node is added by default. You can specify the reactions occurring on the electrode material, giving rise to fluxes in and out from the electrode particles, using Porous Electrode Reaction subnodes. Also add a Porous Matrix Double-Layer Capacitance and, for the Battery with Binary Electrolyte interface, a Porous Matrix Adsorption/Desorption Reaction subnode.
