Dataset on broadband Electrochemical Impedance Spectroscopy of Lithium-Ion Batteries for Different Values of the State of Charge

The Electrochemical impedance spectroscopy (EIS) were measured on four brand new Samsung cylindrical ICR18650-26J rechargeable lithium-Ion batteries at SoC 100%, 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, and 10%. The measurements were repeated six times for each battery. Measurements on other batteries will be added to the dataset when available.
Please note that the measurements in the present dataset are NOT included in the previous (linked) dataset from the same authors.

All EIS spectrum was computed measuring impedance at frequencies [ 0.05, 0.1, 0.2, 0.4, 1, 2, 4, 10, 20, 40, 100, 200, 400, 1000] Hz.
Impedance values are in the format: Re{Z}+Im{Z}j

MEASURE_ID: the unique identification code of each EIS measurement
SOC: state of charge of the battery
BATTERY_ID: the unique identification code of the battery
FREQUENCY_ID: frequency id. Lookup into the frequencies.csv file to get the value in Hertz
IMPEDANCE_VALUE: measured complex impedance value in Ohm in the format: (Re{Z}+Im{Z}j)

6 measurements x 4 batteries x 10 SOC x 14 fequencies = 3360 impedance values (rows)
