The Impact of Upper Cut-Off Voltage on the Cycling Performance of Li-Ion Cells with Positive Electrodes Having Various Nickel Contents

The charge-discharge cycling performance of pouch cells with single crystal LiNi0.5Mn0.3Co0.2O2 (SC532), LiNi0.8Mn0.1Co0.1O2 (SC811) and a prototype polycrystalline Co-free core shell material with an average 94% Ni content (Ni94) were compared in this work. Two upper cut-off voltages (UCVs) per cel...
