Operando Monitoring of InterfacialChemistries and Potentials on Ni-Rich NCM811 Using Ambient PressureX-ray Photoelectron Spectroscopy

Abstract Ni-rich layered transition metal (TM) oxides, such as Li1+x[Ni0.8Co0.1Mn0.1]1–xO2 (NCM811), are widely used as state-of-the-art cathode active materials (CAMs) in lithium-ion batteries (LIBs). At high Ni-contents, however, these materials suffer from surface instability,...
