UConn-ISU-ILCC LFP/Gr Battery Aging Dataset

This dataset encompasses 64 LithiumWerks APR18650M1B cells cycled under 11 unique conditions until they reached their end-of-life at 80% remaining capacity. Cycling tests were interrupted approximately every 3.5 days (~100 cycles, depending on the conditions) to perform a reference performance test (RPT). During the RPT, the cell’s current capacity is measured, and several 100-second-long CC pulses are recorded at three states of charge. The cycling and RPT data are sampled at 1Hz and span over 38 weeks of testing. The short-duration pulses are shown to have a high correlation with the cell’s state of health, with implementation details provided in Nowacki et al. (https://doi.org/10.1016/j.jpowsour.2024.235813). Additional details on cycling protocols, RPT diagnostics, and the raw data format are provided in the “README.txt” file below.
