O3-type layered oxides have been extensively studied as cathode materials for sodium-ion batteries due to their high reversible capacity and initial sodium content, but they suffer from complex phase transitions an unstable structure during intercalation/deintercalation. Herein, we synthesize a high-entropy transition metal oxide, NaNi0.3Cu0.05Fe0.1Mn0.3Mg0.05Ti0.2O2 (NCFMMT), by simultaneously doping Cu, Mg, Ti into its layers, which greatly increase structural entropy, thereby reducing formation energy enhancing stability. The NCFMMT exhibits significantly improved cycling stability (capacity retention of 81.4% at 1C after 250 cycles 86.8% 5C 500 cycles) compared pristine NaNi0.3Fe0.4Mn0.3O2 (71% 100 1C), well remarkable air Finally, the NCFMMT//hard carbon full-cell deliver 103 mAh g–1 1C, with 83.8 maintained 300 81.4%).
