P2-type Mn-Fe-Cu-based cathode materials have garnered enormous attention as potential candidates for sodium-ion batteries (SIBs). Nevertheless, the detrimental phase transition and irreversible oxygen release cause significant capacity degradation poor cycling stability, thereby decelerating their application progress. Herein, we develop a novel P2-Na0.65Ca0.05Mn0.55Co0.05Fe0.2Cu0.2O2 material via codoping with Co Ca ions. The incorporation of Co3+ ions into Mn sites not only mitigates Jahn-Teller distortion Mn3+ to hinder but also activates anionic redox activity by establishing stable CoO6 octahedron. substitution Ca2+ Na enhances stability Na+ transport pathway suppresses sliding TMO2 layers constructing stronger Ca-O bond. Under synergistic effect Co/Ca codoping, shows enhanced diffusion kinetics, improved intrinsic conductivity, alleviated electrolyte corrosion, decreased cell volume variation during extraction/insertion. Consequently, electrode exhibits high initial discharge (125.9 mA h g-1 at 0.2 C), an excellent rate performance (79.6 10 outstanding long-cycle (73.2% retention after 1000 cycles C). This strategy highlights promising opportunity advance practical in high-performance SIBs.

Abstract Sodium‐ion batteries (SIBs) have emerged as a promising candidate for next‐generation energy storage systems owing to their inherent cost advantages. Nevertheless, the practical implementation of SIBs faces critical limitations in density compared commercial lithium‐ion (LIBs), posing significant barrier widespread applications. Enhancing through both development high specific cathode materials and elevated operational voltages represents dual‐pronged strategic approach. However, voltage elevation typically accelerates system degradation multiple mechanisms including accelerated electrolyte decomposition, loss reactive oxygen, particle cracking, transition metal cation (TM n+ ) migration deposition. This review summarizes key challenges from operated at high‐voltages, discuss main strategies overcome these terms layered oxide design. The purpose this is shed light on fundamental science behind challenges, provide potential solutions achieving goal high‐energy SIBs.
