Building on this established theory and the acknowledged path dependence overpotential in electrode materials , our study evaluates the influence that applied rate has on subsequent cycling performance, demonstrating the emergence of a kinetically induced memory effect and its impact on the overpotentials and capacities at fast (dis)charge rates. Further, herein, we demonstrate this to be a general phenomenon in electrodes that exhibit a first-order phase transition upon (dis)charge. Implying operando monitoring of individual electrode crystallites we reveal the role of the active particle fraction, while electrochemical phase-field simulations deepen the understanding of the underlying mechanism. We conclude by recognizing the pivotal role of preceding applied rates in shaping the voltage profile, and its importance on SOC estimation and fast-charging protocols optimization in large-scale aleatory systems coupled with LIBs 22 .
