Tuning local chemistry of P2 layered-oxide cathode for high energy and long cycles of sodium-ion battery
High-capacity and structural stable cathode materials are challenges for sodium-ion batteries. Here, the authors report a layered P2-Na0.612K0.056MnO2 with large-sized K+ riveted in the Na-layers to enable 0.9 Na+ (de)insertion with a reversible phase transition of P2-P’2.
