At 100% DoD, the majority of the interface between CBD and electrolyte (i.e., for subvolumes 1 and 2, approximately 70%, for Subvolume 3, ~ 90% and for Subvolume 4 ~80%) is covered under polysulfides, reducing the active area. However, as expected, the active areas near unutilised sulfur are free to form solid deposits. It is interesting to note that while the normalised discharge behaviour showed Subvolumes 2 and 4 to behave similarly (and Subvolume 1 to out-perform all), when considering the polysulfide deposition behaviour, Subvolumes 1 and 2 have similar levels of coverage to each other at all DoD, and the lowest amount of coverage compared to the other two subvolumes. This is despite the different inherent porosities, sulfur volume fractions, effective local E/S ratios and S/SSA ratios. This, again, highlights the effect the microstructure, rather than the subvolume-averaged parameters, has on the local performance of the electrode and the strength of the 3D modelling approach taken here.
