Tailoring the surface properties of LiNi0.4Mn0.4Co0.2O2by titanium substitution for improved high voltage cycling performance

Abstract
LiNi0.4Mn0.4Co0.2O2cathodes with and without Ti substitution were cycled to equivalent degrees of Li removal and transition metal oxidation states on electrode surfaces were probed using X-ray absorption spectroscopy.
