I am modeling capacity fade in lithium ion cells. I have multiple side reactions modelled as different porous electrode reactions. For modeling particle intercalation- boundary condition at the particle surface, I want the contribution of current density from only one of the porous electrode reaction models. But by default, the setting in COMSOL battery design module, sums over all the current densities from different porous electrode reactions modelled under that porous electrode node. Can someone guide me on how to change that to include only intercalation current density and not side reaction current density for particle surface BC.
