Abstract

Sodium-Ion Batteries Anionic redox in Na-based layered oxide cathodes unlocks extra capacity beyond transition metal limits, enabling high-energy sodium-ion batteries. In Review e12974, Maximilian Fichtner, Prabeer Barpanda, Senthilkumar Baskar, and co-workers discuss coupled cationic–anionic mechanisms in P2, O3, and related structures, key challenges such as voltage hysteresis, oxygen loss and degradation. It further highlights design strategies and advanced characterizations to correlate structure, properties and performances.
