In-situ surface coating and subsurface gradient doping contrives P2-Na0.67Ni0.33Mn0.67O2 single crystal with highly stable interface and structure

P2-Na0.67Ni0.33Mn0.67O2 cathode holds the merits of high working voltage/capacity, facile manufacture, and similar large-scale production to Li layered oxides. However, it suffers from issues of irreversible P2–O2 phase transition at a high voltage (>4.0 V), interfacial instability, and particle...
