Description:
The data set is based on 1100 commercial production fresh lithium-ion cells being part of two batches. The investigated cell is a commercial 3Ah LiFePO4-graphite cell (SONYUS26650FTC1). Each cell has been measured by a DC Check-Up (CU) routine and an AC Electrical Impedance Spectroscopy (EIS). By evaluating the measurement data, 15 cell parameters have been determined for each cell: Different discharge capacities, different DC and AC impedances, the mass and the mean temperature during CU of the...     »
