Since the deposition of solid polysulfides, i.e., Li2S2 and Li2S, over an electrochemically active surface area affects the performance, it is important to understand the interplay between discharge rates, DoD and electrode microstructure. Here, electrochemically active surface area refers to the interface between the electrolyte and CBD, and, as previously stated, we are assuming the CBD to be solid and non-porous. With this modelling approach, it is not possible to model the morphology or thickness of the deposits, but we are able to predict their location, and the percentage of the available surface area covered with solid polysulfides; therefore, the effect on the subsequent performance once non-conductive deposits have formed on a portion of the CBD is accounted for in this model. In a real system, the solid polysulfide deposits would likely be more 3D in nature, and therefore we are likely to be overestimating the fraction of CBD surface that is rendered inactive via the assumed 2D film deposits in our model; nevertheless, it is still valuable to study the effect the microstructure has on the heterogeneity of deposits in the electrode. Figure depicts the extent of deposition of polysulfides on an electrochemically active surface area at each subvolume, obtained at 50%, 80% and 100% DoD and at the global discharge rate of C/10.
