Abstract

Abstract:

The O3-type sodium nickel-iron-manganese oxide cathode materials are widely applied in the field of large-scale energy storage systems due to high theoretical capacities，better low-temperature performance，safety performances and so on.The modification of O3-type sodium nickel-iron-manganese oxide cathode materials have been recognized as a key technical approach，by which the cycling performance and fast charging/discharging capabilities of sodium-ion batteries are effectively enhanced.Herein，recent advances in the modification strategies for O3-type cathode materials were systematically summarized，an in-depth analysis of the impacts of element doping，surface coating，high-entropy design，and multiphase design on the material performance was provided，and potential pathways for optimizing these modification approaches were discussed.Through analysis，these modification strategies were found to effectively address irreversible phase transition and low sodium-ion diffusion rate，thereby enhancing the cycling life and fast charging/discharging performance of sodium-ion batteries.Meanwhile，existing limitations，including the high cost of materials and complex synthesis processes，were highlighted in this paper，and perspectives on the future development of high-performance cathode materials for sodium-ion batteries were offered.

Key words: sodium-ion batteries, cathode materials, O3-type sodium nickel-iron-manganese oxide, electrochemical performance, modification strategies
