Abstract

Mn dissolution is dominantly responsible for capacity fading of most Mn-rich cathodes. Here the authors reveal that soluble Mn2+ species significantly destabilizes solvent and anion via its unique solvation sheath structure, providing insight into the failure mechanism of related cathode chemistries.
