Data for A comparison between electrochemical impedance spectroscopy and incremental capacity-differential voltage as li-ion diagnostic techniques to identify and quantify the effects of degradation modes within battery management systems

For an experimental case of parallelized cells aged differently, the effects due to LAM and LLI were found to be the most pertinent, outlining that both techniques are correlated. This approach can be further implemented within a BMS to quantify the causes of battery ageing which would support battery lifetime control strategies and future battery designs.<br><br>Characterisation test on four cells Under 01_Capacity_and_Pseudo_OCV folder: 1C capacity test and pseudo-OCV test.

Under 02_EIS folder there are two folders: 01_EIS_measurements and 02_EIS_fitting_results. 01_EIS_measurements contains EIS data for SoC 20%, 50% and 90%. Each mat file contains all the snapshots (columns 1-11, snapshot 1 to 11) and cells (rows 1-4, Cell 1 to 4). 02_EIS_fitting_results contains fitting results of the EIS data for the Adapted-Randles Equivalent Circuit Model chosen.
