Oxygen Vacancy Engineering and Pre-accommodated Distortion Stabilization Enabling Superior Rate and Cycling Performance in P2-Type Mn-Rich Cathodes.
P2-type layered oxides have been considered as an ideal cathode material for sodium-ion batteries (SIBs) due to their high capacity and facile synthesis, yet their practical application is severely hampered by Jahn-Teller distortion, manganese dissolution, and poor intrinsic ionic conductivity. While conventional catio...
