Abstract:

Ni-rich LiNi0.6Co0.2Mn0.2O2 (NCM) and LiNbO3-protected LiNi0.6Co0.2Mn0.2O2 (NCM) thin-film cathodes have been prepared by radio frequency (RF) magnetron sputtering. Electrochemical investigations show enhanced stability of LiNbO3-protected cathodes compared with bare LiNi0.6Co0.2Mn0.2O2. The interfacial interaction of LiNbO3 and LiNi0.6Co0.2Mn0.2O2 layers has been investigated by XPS depth profiling and demonstrated different cathode electrolyte interface (CEI) film formation processes at the electrodes. The results elaborate on the interaction between LiNbO3 and LiNi0.6Co0.2Mn0.2O2, emphasizing the role of the LiNbO3 layer in improving the cycling performance of Ni-rich cathodes.
