Résumé |
7Li MAS NMR quantification of lithiated species at the surface of aged NMC811 industrial powders and slurries shows that the electrode preparation process exacerbates Li extraction. A combination of 7Li MAS NMR and XPS suggest a new reaction for the PVdF binder degradation, involving in fact Li2O as the reagent and the formation of LiF.
