Lithium-ion battery dataset with impedance measurements at every cycle under high current conditions

<p dir="ltr">This dataset includes all the measurements resulting from a <u>spectroscopy characterization and life testing campaign</u> carried out on Li-ion batteries considering:</p><p dir="ltr">· A fast discharge rate of 4C (i.e., 10 A) and a fast charge rate of 1.6C (i.e., 4 A).</p><p dir="ltr">· A total of 400 cycles.</p><p dir="ltr">· EIS measurements acquired each cycle at 100% of the State of Charge in a frequency range 50 mHz ~ 50 kHz with ten datapoints per decade.</p><p dir="ltr">The dataset contains time series of current, voltage, capacity, temperature, and internal resistance, together with per-cycle summaries and per-cycle impedance spectra for each cell under investigation.

The data enable analysis of degradation trends under sustained high current operation and provide detailed information on impedance evolution throughout the cycling campaign. <br></p>
