Dataset on broadband Electrochemical Impedance Spectroscopy of Lithium-Ion Batteries for Different Values of the State of Charge
Description
Electrochemical impedance spectroscopy (EIS) on rechargeable lithium-Ion batteries. The EIS were measured on three brand new Samsung cylindrical ICR18650-26J 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 are going to be added 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 IMPEDANCE.CSV FILE ------------------------ 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) FREQUENCIES.CSV FILE --------------------------- FREQUENCY_ID: frequency identification code FREQUENCY_VALUE: frequency value in Hertz
