Recent progress and modification of manganese-based layered transition metal oxide cathode materials for sodium-ion batteries
This article summarizes the current research status of manganese-based materials as cathode materials for sodium-ion batteries,focusing on the effects of their structural characteristics,doping modifi-cation,and optimization strategies on electrochemical performance.Manganese-based materials have at-tracted much attention due to their low cost and abundant resources,but their cycle stability and rate per-formance still need to be improved.Research has revealed that by fine-tuning the material structure,intro-ducing doping elements,and optimizing the preparation process,the conductivity,structural stability,and sodium ion diffusion kinetics of the material can be significantly enhanced,thereby improving the battery performance.This article also summarizes the advantages and disadvantages of current preparation meth-ods,and looks forward to future research directions,aiming to provide theoretical guidance and reference for promoting the performance optimization and practical application of manganese-based cathode materi-als for sodium-ion batteries.
