Transition-Metal-Oxygen Covalency Controls Ligand-Hole Stability in Li-Rich Cathode

Lithium-rich cathodes boast a large specific capacity due to the presence of excess lithium per transition metal. However, making use of that excess Li drives the cathodes to unusually high formal oxidation states, often triggering unwanted side reactions, typically signaled by gas release and commonly associated with...
