Potassium‐Ion Storage(#br)In article number 2203976, Songping Wu, Zhiguang Xu, Yurong Yan, and co‐workers successfully fabricate 2D bismuth@N‐doped carbon sheets with a powerful Bi?O?C bond and internal void space for achieving ultrahigh rate and stable potassium‐ion storage. The influence of interface microstructure and chemical coupling on the electrochemical properties are revealed by ex/in‐situ techniques and density functional theory calculation.
