[OLD] Data For: Dataset on broadband Electrochemical Impedance Spectroscopy of Lithium-Ion Batteries for Different Values of the State of Charge
Description
=== NEW DATASET NOTICE ===== We published a new dataset obtained with an improved data acquisition protocol and new measurements. We suggest considering the new dataset. =============================== Electrochemical impedance spectroscopy (EIS) on rechargeable lithium-Ion batteries. The EIS were measured on ten brand new Samsung cylindrical ICR18650-26J lithium-Ion batteries at SoC 100%, 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, and 10%. For three of the batteries, the measurements were repeated twice. (13 CSV files ,130 EIS in total). File : Data Source ------------------------------------------- EIS_BATT_1: Battery 1 Measurement 1 EIS_BATT_2: Battery 1 Measurement 2 EIS_BATT_3: Battery 2 Measurement 1 EIS_BATT_4: Battery 2 Measurement 2 EIS_BATT_5: Battery 3 Measurement 1 EIS_BATT_6: Battery 4 Measurement 1 EIS_BATT_7: Battery 5 Measurement 1 EIS_BATT_8: Battery 5 Measurement 1 EIS_BATT_9: Battery 6 Measurement 1 EIS_BATT_10: Battery 7 Measurement 1 EIS_BATT_11: Battery 8 Measurement 1 EIS_BATT_12: Battery 9 Measurement 1 EIS_BATT_13: Battery 10 Measurement 1 Each CSV file contains ten columns. Each column in the CSV file contains data of an EIS spectrum measured at one specific SoC. The first column is for SoC 100%. The last column is for SoC 10%. SoC Columns headers row (non included in the file) is: ['100','090','080','070','060','050','040','030','020','010'] 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}i One impedance value for each row: Row #1: 0.05 Hz Row #2: 0.1 Hz Row #3: 0.2 Hz ... Row 14: 1000 Hz.
