Description:
In recent years, in-depth analysis of the manifold properties of commercial lithium-ion batteries has gained increasing attention, as it fosters optimized design and operational strategies of battery-powered applications such as battery electric vehicles. However, various properties are not easily accessible and experimental determination requires intensive efforts in the battery lab. In this study, we have performed a tear-downanalysis of a commercially available lithium-ion cell with a silicon...     »
Method of data assessment:
18650 lithium-ion battery cells of type Sony US18650VTC5 A with a Si-doped graphite anode, NCA cathode, and 2.5Ah nominal capacity were examined with battery test systems of type BaSyTec CTS Lab and Gamry Instruments Interface 5000 inside the battery laboratory of the Institute of Automotive Technology.
Key words:
Lithium-ion batteries; Teardown analysis; Si-doped graphite anode; Ni-rich NCA cathode; Half cells; Electrochemical impedance spectroscopy; Open-circuit voltage
