Publication on the voltage-dependent charge compensation mechanism and cathode electrolyte interface stability of the lithium-ion battery cathode materials LCO and NMC333 studied by XPS

Mellin et al. used in-vacuo scratching combined with carbon- and binder-free preparation of battery cathode materials, leading to well-defined XPS core-level spectra.

Thus it was possible to examine the voltage-dependent charge compensation mechanism and the cathode electrolyte interface stability of the cathode powders LiCoO₂ and LiNi_1/3Mn_1/3Co_1/3O₂.
