The Operation Dependence of C − N Fatigue for Lithium‐Ion Batteries

The dataset contains the cycling data, i.e., voltage, current, capacity, rest, and step time, of all of the 49 groups 683 LISHEN LFP, LISHEN NMC, LISHEN NCA, LG NCA and SAMSUNG NCA batteries measured at various charging-discharging rates and temperatures. The raw data files, in excel format, are named with the battery types and the corresponding cycling conditions. For example, ‘LISHEN_NMC_1.0C-3.0D_T25_xxx’ indicates the battery is LISHEN NMC type battery, charged with 1.0C and discharged with 3.0C in CC stages during the CCCV cycling at 25 Celsius, and xxx denotes the xxx-th battery cycled in this condition. The C-N curves are plotted by extracting the cycle life N from the ‘Cycle number’ in raw excel data file, when the discharging capacity (denoted as 'DChg. Cap.(mAh)', sheet 1, 4th column) falls below 80% of their nominal capacity. The nominal capacity is 1500, 2600, 3350 mAh for the LFP, NMC and NCA type batteries, respectively.
