Avoiding severe structural distortion, irreversible phase transition, and realizing the stabilized multielectron redox are vital for promoting the development of high‐performance NASICON‐type cathode materials for sodium‐ion batteries (SIBs). Herein, a high‐entropy Na3.45V0.4Fe0.4Ti0.4Mn0.45Cr0.35(P...
