2026-08-07 About the data set of the article "Preparation and Sodium Storage Performance of Distillers’ grains Hard Carbon Materials" doi:10.57760/sciencedb.45620 en Process diagram, elemental analysis, infrared, XRD, BET, XPS, SEM, TEM high-resolution images, and sodium electrical properties of hard carbon materials prepared by different methods from distiller's grains. 1. Software tools used for data: (1) Data analysis software: such as Origin, Excel, etc., used for organizing, plotting, and analyzing experimental data in datasets. (2) Material characterization data analysis software: For material structure and morphology characterization data, such as XRD, SEM, TEM, etc., corresponding professional software is required for data processing and analysis. For example, using MDI Jade 6 software to perform phase structure analysis on XRD data, determining the crystal structure and phase composition of the material; Analyze XPS data using Avantage; Use Project FIVE 5.2 to analyze Raman spectroscopy data. (3) Electrochemical testing data analysis software: such as Zview for electrochemical impedance spectroscopy analysis, and Xinwei testing system for electrochemical data analysis. 2. The content and description information of the data file: According to the main text of the paper and the arrangement of data in the SI, each data file has been numbered, with one file corresponding to one image. For example, Fig.1 corresponds to Figure 1 in the main text, and S1 corresponds to Fig.S1 in the supporting material (SI). EXCEL containing data for each file, including corresponding images such as a, b, c, etc  Distillers’ grains; Biomass; Hard carbon; Sodium-ion batteries; Hydrothermal treatment Liu Xinyi Weifeng Liu RESTRICTED dataset Science Data Bank
