Data and code for: Protocol-aware standardization of relaxation-induced kinetic masking in incremental capacity fingerprints of lithium-ion batteries

This record contains the processed reference performance test (RPT) data, metadata, MATLAB codes, and result tables supporting the JMCA manuscript entitled “Protocol-aware standardization of relaxation-induced kinetic masking in incremental capacity fingerprints of lithium-ion batteries”. The package includes processed complete-RPT data files, the associated charge metadata table, the final leave-one-cell-out validation codes for the baseline tau(U) model and the temperature-aware tau(U,T) extension, the required external IC-processing function, and the exported result tables used for the reported validation statistics. Figure-generation scripts are not included in this repository. The deposited files are intended to provide the core data and analysis code required to understand and verify the main results reported in the manuscript.
