The dataset of the paper "Optimizing pore structure and surface chemistry by soft carbon coating to boost high-rate sodium storage performance of hard carbon" published in the journal "New Carbon Materials"

1. Software Tools for Data Processing:  (1) Data Analysis Software: Tools such as Origin and Excel were used to organize, plot, and analyze experimental data from the dataset.  (2) Material characterization data analysis software: For structural and morphological characterization data such as XRD, SEM, and TEM, specialized software is required for data processing and analysis. For example, MDI Jade 6 software is employed for phase structure analysis of XRD data to determine crystal structure and phase composition; Avantage software is used for XPS data analysis; Project FIVE 5.2 is utilized for Raman spectroscopy data analysis. (3) Electrochemical testing data analysis software: such as Zview for electrochemical impedance spectroscopy analysis, and Neware testing system for electrochemical data analysis.2. Data File Contents and Descriptions:  Based on the arrangement of data files in the main text and the SI (Supporting Information), each dataset has been assigned a unique identifier, where one file corresponds to one figure. For example, Fig. 1 corresponds to Figure 1 in the main text, and Fig. S1 corresponds to Figure S1 in the SI. Additionally, each image within a file has been labeled accordingly. For instance, Fig. 1a, Fig. 1b... correspond to Fig. 1a, Fig. 1b... in the main text, respectively. Similarly, Fig. S1a, Fig. S1b... correspond to Fig. S1a, Fig. S1b... in the SI, respectively.
