2026-07-20 /The data of the article“Heat Treatment and Chemical Prelithiation Potential-Drive for High‑Efficiency Regeneration and Repair of Spent Graphite Anodes” doi:10.57760/sciencedb.jim.00080 en This dataset contains all the original data and chart files that support the research conclusions of this paper. The specific contents are as follows:1. Original plotting data ("Origin Original Data" folder): It includes all the underlying basic data used to draw the main figures in the paper (Figures 1-6) and supplementary supporting information figures. The data types cover Raman spectroscopy (Raman), X-ray diffraction spectra (XRD), N₂ adsorption-desorption isotherms and pore size distribution curves (BET), cyclic voltammogram (CV), constant current charge-discharge curves, rate performance data, cycle performance data, electrochemical impedance spectroscopy (EIS), relaxation time distribution (DRT) data, X-ray photoelectron spectroscopy (XPS), and full battery performance data. These data can be read by data processing software such as Origin, facilitating other researchers to reproduce the experimental charts or conduct secondary data mining. 2. Image files (in .png/.jpg formats): These include all the high-resolution images used in the paper. They cover schematic diagrams of material synthesis and regeneration repair mechanisms (Fig. 6), microscopic morphology and structure diagrams based on SEM, spectra for characterizing material structure and graphiteification degree, as well as detailed electrochemical performance display diagrams. 3. Layout source file (in .pptx format): Provides the PPT source file used for assembling the original layout images, showing the processing, annotation and stitching process of the images.4. SEM original images: The original SEM images used to characterize the microstructure of Gr anode (SGr, SGr-600, SGr-1500, HGr, RGr, etc.) at different processing stages. These untrimmed and unformatted original images are available for peers to view and verify key microscopic structural features such as the evolution of material surface morphology, fragmentation degree and interface layer reconstruction. lithium-ion battery; spent graphite; regeneration and restoration; chemical pre-lithiation; initial Coul- ombic efficiency jiang jiang min Xu Chencheng Zhuang Quanchao Ju Zhicheng PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset Science Data Bank
