Separator
Use a Separator node to model electrolyte charge and mass transport in an electronically isolating porous matrix. Use correction factors to account for the lowered diffusion coefficients in the electrolyte and the lowered conductivities of the electrode, due to the lower volume fractions of each phase and the tortuosity of the porous matrix.
See also the Electrolyte node for more information about the Diffusion and Migration in Electric Field settings of this node.
