3. Introduction to the data set
A total of 1350 cycles. OCV under small current, internal resistance, DST/UDDS condition, and capacity test were completed every 50 cycles. The aging process is at 30°C with different discharge rates (0.5C, 1C, 1.5C, 2C), and different SOC intervals (0 ~20%, 0~50%, 0~100%, 10-90%, 20~30%, 25~75%, 40~60%, 50~100%, 80~100%, 90~100%).
