The situation gets more complicated when considering smaller C rates. Comparing to the twostage process that we discussed at 1C, we can see that at 0.1C the SOC curves intersect at around 60% of the discharge depth (Figure (b)). At this point, the relative concentration of lithium within graphite becomes larger than that of Si. Looking at the evolution of the current contributions, we can see in Figure (c) that the behavior of the electrode is considerably more irregular at 0.1C. This interweaved profiles show a complex interplay between the AM phases in the composite electrode that cannot be easily interpreted. However, a rather simple realization is that, due to the low applied current, the overpotential that is generated from the Faradaic reactions is omittable. In turn, the electrode potential of both phases will basically follow their respective OCVs. By revising the SOC curves, we can see that their intersection points coincide with those of their respective OCV curves, where each slope changes corresponding to a phase transition of graphite. Therefore,
