196 cells from the same production batch of commercial 18650 cells of type US18650VTC5A by Sony/Murata with a nominal capacity of 2.5 Ah were aged under different conditions. The anode active material is silicon-graphite (SiG) with 1.4 wt% silicon and the cathode active material is nickel-cobaltaluminum (NCA) with the formulation LiNi0.80Co0.15Al0.05O. All CU measurements were performed using BaSyTec cell test systems (CTS). Additionally, for cycling with higher currents, the BaSyTec XCTS MKII w...     »
Beschreibung:
In this study, we analyze data collected during the aging of 196 commercial lithium-ion cells with a silicon-doped graphite anode and nickel-rich NCA cathode. The cells are aged over a large range of calendar and cycle aging conditions. For different cells, these conditions are constant, alternating or randomly changing. The total test time and reached cycles are 697 days and 1500 equivalent full cycles for the calendar and cyclic aging tests respectively. A periodic check-up procedure was consi...     »
