💡 Novelty & Significance:
This review uniquely addresses air sensitivity and residual alkali in sodium-ion layered oxide cathodes, highlighting sodium-specific challenges absent in lithium-ion systems: NaHCO₃ formation, severe Na⁺/H⁺ exchange, and narrow processing windows. It bridges formation mechanisms, characterization, and modification strategies, offering future perspectives to guide practical, air-stable, high-performance cathode development.
