Compact Early-Cycle Descriptors Reveal Empirical Charge–Discharge Imbalance as a Key Predictor of Long-Horizon Lithium–Sulfur Battery Degradation

This repository contains the processed data, derived descriptors, analysis code, and model-evaluation outputs supporting the manuscript “Compact Early-Cycle Descriptors Reveal Empirical Charge–Discharge Imbalance as a Key Predictor of Long-Horizon Lithium–Sulfur Battery Degradation.” The released materials support the descriptor-based long-horizon degradation prediction analyses reported in the study, including capacity-based representations, empirical charge–discharge imbalance descriptors, capacity-morphology and voltage-related descriptors, descriptor-group comparisons, feature-replacement analysis, within-cell centering sensitivity tests, trajectory baselines, and robustness analyses. The repository contains processed and analysis-ready research data rather than the complete raw cell-level cycling archive. Details of the dataset structure, feature definitions, modelling configuration, and reproducibility scope are provided in the accompanying documentation.
