Fig. 4: Current behaviour in a 6C discharge for the four modelled systems.

a\(\varDelta \bar{R}=0\), b\(\varDelta \bar{R}=1\), c \(\varDelta \bar{R}=5\) and d \(\varDelta \bar{R}=10\). The index k counts along the cell thickness direction (i.e., in Fig. 3(a), \(k=1\) for the top unit and \(k=5\) for the bottom unit). The simulation conditions are the same as for Fig. 3.
