The dataset from Sandia National Labs used in the publication, “Degradation of Commercial Lithium-ion Cells as a Function of Chemistry and Cycling Conditions,” consists of commercial 18650 NCA, NMC, and LFP cells cycled to 80% capacity (although cycling is still ongoing). This study examines the influence of temperature, depth of discharge (DOD), and discharge current on the long-term degradation of the commercial cells.
