With further increase in DoD, electrochemically active surface areas are covered under precipitation with more extensive deposition observed towards the separator. The amount of electrochemically active surface area covered by polysulfide deposition was ~20% for Subvolumes 1 and 2, ~35% for Subvolume 3 and 30% for Subvolume 4. This is in accordance with previously developed 1D models, although they of course cannot spatially resolve this deposition behaviour in 3D .
