Figure displays the effect of sulfur dissolution on the tortuosity and flux of electrolyte, which in turn represents the Li + distribution throughout the electrode. The tortuosity factor describes resistance to the free flow due to convoluted paths present in the porous media. Tortuosity factor, when applied to the fluid phase represents the resistance to diffusive flow, and, when applied to the solid phase, represents the resistance to the electron transfer. The initial heterogeneous distribution of solid sulfur and electrolyte impacts the dissolution of sulfur in liquid electrolyte, altering the microstructure of the electrode. The effect of S8 dissolution on Li-ion flux is defined by Fick's law, which is a function of both the tortuosity and porosity of the electrode. In the current model, limitations on changing morphology mean that the dissolution process cannot be incorporated into the electrochemical model; however, as discussed later, approaches to account for dissolution (and precipitation of solid polysulfides) will be explored in future work. In this section, we evaluate the effect of changing microstructure, due to sulfur dissolution (approximated by using an erosion technique on the S material voxels of the CT data) on the tortuosity of the electrode to highlight the effect of dynamic changes in microstructure in the early stages of the discharge cycle.
