摘要
Abstract
Layered oxides have emerged as one of the most promising cathode materials for commer-cialized sodium-ion batteries(SIBs)due to their abundant resources and low cost.However,these ma-terials still face critical challenges during cycling,including structural degradation,intense interfacial side reactions,and poor air stability,which severely limit their practical electrochemical performance and long-term cycling life.This review systematically addresses challenges in the structure,inter-faces,and air stability of layered oxide cathodes,focusing on two key strategies:intrinsic structural regulation and surface/interface function optimization,and summarizes recent significant advances in related research.Advanced synthesis methods,phase structure design,and ion doping strategies en-hance the bulk stability of materials.Surface coating and optimized electrolyte composition contrib-ute to constructing highly stable electrode/electrolyte interfaces.Enhancing the multidimensional sta-bility of layered oxide cathodes provides a theoretical basis and technical pathway for their rational design and practical development.关键词
