Cover Feature: Unravelling Charge Carrier Mobility in d ₀ ‐Metal‐based Spinels (Batteries & Supercaps 7/2022)

The Cover Feature illustrates properties of the potential energy surface for charge carriers in spinel solid electrolyte and electrode materials that yield a descriptor for the ion mobility. The descriptor is based on the energetic difference between the two symmetrically different intercalation sites in these materials. This allows to predict the height of the minimum migration barrier without the need to perform numerically costly transition state searches. At the same time, it improves our understanding of ion mobility which is a critical performance parameter of batteries. More information can be found in the Research Article by H. Euchner and co-workers.
