Abstract In recent decades, sodium‐ion batteries (SIBs) have received increasing attention because they offer cost and safety advantages avoid the challenges related to limited lithium/cobalt/nickel resources environmental pollution. Because sodium storage performance production of SIBs are dominated by cathode performance, developing materials with large‐scale capacity is key achieving commercial applications SIBs. Therefore, host high energy density, long cycling life, low cost, chemical/environmental stability crucial for implementing advanced Among developed SIBs, O3‐type sodiated transition‐metal oxides attracted extensive owing their simple synthesis methods, theoretical specific capacity, sufficient Na content. However, relatively large Na‐ion radius leads sluggish diffusion kinetics inevitable complex phase transitions during deintercalation/intercalation process, resulting in poor rate capability stability. this review comprehensively summarizes research progress modification strategies cathodes, including component design, surface modification, optimization methods. This work aims guide development layered provide technical support next generation energy‐storage systems.

Abstract Sodium‐ion batteries (SIBs) are considered as a low‐cost complementary or alternative system to prestigious lithium‐ion (LIBs) because of their similar working principle LIBs, cost‐effectiveness, and sustainable availability sodium resources, especially in large‐scale energy storage systems (EESs). Among various cathode candidates for SIBs, Na‐based layered transition metal oxides have received extensive attention relatively large specific capacity, high operating potential, facile synthesis, environmental benignity. However, there series fatal issues terms poor air stability, unstable cathode/electrolyte interphase, irreversible phase that lead unsatisfactory battery performance from the perspective preparation application, outside inside oxide cathodes, which severely limit practical application. This work is meant review these critical problems associated with cathodes understand fundamental roots degradation mechanisms, provide comprehensive summary mainstream modification strategies including chemical substitution, surface modification, structure modulation, so forth, concentrating on how improve reduce interfacial side reaction, suppress realizing structural reversibility, fast Na + kinetics, superior electrochemical performance. The advantages disadvantages different discussed, insights into future challenges opportunities also presented. image
