Furthermore, it is noted that as current density increases, the overall K + concentration required to achieve localized K + enrichment (also the CDC in cathode‐electrolyte interface) shows a decreasing trend (0.2→0.1→0.03K), suggesting that the coupling of ion migration and external current reduces the critical K + requirement for the K + ‐rich layer formation.
