Abstract Mn‐based layered oxides have garnered significant attention as cathode materials for energy storage due to their environmental benignity and high theoretical specific capacity. However, practical applications remain constrained by sluggish Na + intercalation kinetics poor structural stability.

This work elucidates critical role optimizing interactions between transition metal atoms, establishing relationship structure properties. These findings advance development high‐performance technologies.
