UConn-ILCC NMC/Gr Battery Aging Dataset

This dataset encompasses 44 Panasonic UR18650AA cells cycled under 11 unique conditions until an end-of-life of 65% remaining capacity. Cycling tests were performed under ambient conditions (~22 degrees Celsius) and were interrupted approximately every 3.5 days (~100 cycles, depending on the charge rate, discharge rate, and depth of discharge) to perform a reference performance test (RPT). During the RPT, the cell’s remaining capacity is measured, and 100-second-long, 1C constant-current pulses are conducted at nine states of charge (SOC): 10%, 20%, …, and 90%. The cycling and RPT data are sampled at 1Hz and span over 35 weeks of testing. Additional details on the cycling protocols and RPT diagnostics are provided in Nowacki et al. (DOI to be added soon) and the “README.txt” file attached below.
