It is obvious to observe that, at 50%, 80% and 100% DoD, the local current density is varied with location and above 0 A m -2 , and the maximum current densities are over 5 A m -2 . For Subvolumes 1, 2 and 4, from 50% to 80% DoD, the area where the current densities are generally higher (red) are expanding, and the lower current density areas (blue) are reducing, and as illustrated numerically, the volume-averaged current density is increasing. Subsequently, from 80% to 100% DoD, the trend is reversed, with a decreasing volume-averaged current density. However, for Subvolume 3, it is noted that it has the highest average current density at the evaluated DoD states compared to other sub-volumes. Additionally, the volume-averaged current densities are increasing with DoD, unlike others. This also has implications for the inferior discharging behaviour demonstrated by Subvolume 3 in previous sections; the applied current density is too great for this local microstructure, which prevents Subvolume 3 obtaining the full capacity. For Subvolumes 1, 2 and 4, comparable current densities are applied, and the slightly lower current density which applies to Subvolume 1 yields the best capacity performance.
