1 Introduction Sodium-ion batteries (SIBs) have garnered significant interest as a promising alternative to lithium-ion batteries, primarily due to the high abundance and low cost of sodium resources.[1] The performance of SIBs is heavily dependent on the choice of cathode materials, which include transition-metal layered oxides,[2] Prussian blue analogues,[3] and polyanionic compounds.[4] Among these, polyanionic compounds are particularly noteworthy for their excellent structural stability...

ABSTRACT While high-voltage operation of mid-Ni layered oxide cathodes in full-cell Li-ion batteries is essential for achieving high energy density, it inevitably accelerates electrode degradation, ultimately resulting in capacity loss.
