Enhanced Structural Reversibility and Electrochemical Stability Via Fe3+/Fe4+ Stabilization in a P3‐Type Layered Na0.7[Mn0.5Fe0.4Li0.1]O2 Cathode at High‐Voltages

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Partial Li substitution for Fe in a P3‐Type layered Na0.7[Mn0.5Fe0.4Li0.1]O2 cathode stabilizes the iron redox behavior, particularly at higher charging voltage up to 4.5 V (vs Na/Na+), that enables more reversible sodium‐ion storage capacity and significantly improves capacity retention.
