O3-type layered oxides for sodium-ion batteries (SIBs) have attracted extensive attention due to their inherently sufficient Na content, which been considered as one of the most promising candidates practical applications. However, influenced by irreversible oxygen loss and phase transition O3–P3, cathodes are always limited low cutoff voltages (typically <4.2 V), restraining full release capacity.
