Abstract
Layered transition metal oxides (LTMOs) are considered promising cathode materials for sodium-ion batteries (SIBs) due to their high specific capacity and low cost, making them promising candidates for commercialization. This review focuses on the current state of research on the structure and performance of LTMOs beginning with an explanation of the structure characteristics of P-phase and O-phase cathode materials. Next, to address the issues faced by LTMOs, including irreversible phase transitions during charge–discharge processes, the imbalance between energy density and cycling stability, and poor air stability, three modification strategies, such as element doping, surface coating, and structure design are summarized. Additionally, research on the complementary manganese and oxygen redox chemistry was also elucidated. Finally, an outlook on the development trends and application prospects of LTMOs is proposed, aiming to promote further fundamental research and practical application of SIBs.
期刊介绍:
Energy & Fuels publishes reports of research in the technical area defined by the intersection of the disciplines of chemistry and chemical engineering and the application domain of non-nuclear energy and fuels. This includes research directed at the formation of, exploration for, and production of fossil fuels and biomass; the properties and structure or molecular composition of both raw fuels and refined products; the chemistry involved in the processing and utilization of fuels; fuel cells and their applications; and the analytical and instrumental techniques used in investigations of the foregoing areas.
