Synergistic Al/Ti Co-doping and MgO Surface Engineering of O3-Type NaNi0.5Mn0.5O2 Cathodes for High-Performance Sodium-Ion Batteries

O3-type NaNi0.5Mn0.5O2 is considered a promising cathode material for sodium-ion batteries, but its electrochemical performance is limited by rapid capacity fading associated with Jahn–Teller distortion of Mn3+ and irreversible O3–P3 phase transitions at high voltages. To address these issues, a combined strategy inv...
