Subnodes (one Porous Electrode Reaction is added by default) are used to define the properties of the electrochemical reactions in the electrode. You may also add additional Porous Electrode Reaction and Porous Matrix Double Layer Capacitance subnodes. These subnodes are available by clicking the parent node and selecting it from the Attributes menu, or by right-clicking the parent node.

If the Use simplified reaction kinetics expression for check boxes for the Positive electrode has been enabled in the Porous Electrode Reaction Kinetics section on the top-node, only one single Lithium Insertion Reaction is present, and it cannot be deleted.

The Solid volume fraction (1) is used to calculate the electrode surface area of the electrode. If the battery capacity is defined by Volume fractions on the parent interface node, this setting will also have an impact on the resulting electrode host capacity.

For the remaining settings of this section see the Porous Electrode node in the Lithium-Ion Battery and Battery with Binary Electrolyte interfaces.
