Associated data of the article 'Dual-Site Doping Design and Mechanism Study of High-Stability Manganese-Based Sodium Battery Cathode Materials'

This dataset is the supporting data for the paper "Design and Mechanism Study of Dual Site Doping for High Stability Manganese based Sodium Cathode Materials", covering four core categories of manganese based sodium cathode materials: preparation parameters, structural characterization data, electrochemical performance testing data, and theoretical calculation data. All data were obtained through standardized experimental procedures and instrument testing, which can be directly used to verify the regulatory mechanism of dual site doping on the crystal structure, electronic conductivity, and cycling stability of materials. It can also provide data reference and method borrowing for the doping modification research of sodium positive electrode materials.
