Novel Stress‐Evolution Model for NaNi 1/3 Fe 1/3 Mn 1/3 O 2 Cathodes: Determining Localized Accumulation and Diffusive Transfer Based on Tension‐Compression Asymmetry

ABSTRACT O3‐NaNi 1/3 Fe 1/3 Mn 1/3 O 2 (NFM) is a promising high‐energy‐density cathode for sodium‐ion batteries. However, the long‐term cycling performance is hindered by particle fracture caused by non‐uniform stress distribution. The mechanisms of non‐mechanical stress accumul...
