The Thin Electrode Layer node can be used to model a thin insulating or resistive sheet, located on an interior boundary in an electrode domain. The node can be used as an alternative to drawing the actual layer domain in the model geometry, which may significantly reduce meshing and solver time, especially in 3D models.

The layer may be set to be either Insulating or Resistive.

For the case of Resistive, the Surface Resistance can either be set directly, or calculated from Thickness and Conductivity values.

Enable Slit electrolyte potential in porous electrodes to make the layer fully insulating for the electrolyte phase potential along the selected boundaries.
