Title: Integrating Novel Microscopy into Battery Research: From Atomic Resolution to In Situ and Functional Imaging

Abstract

Regardless of their different configurations and chemistries, current energy-storage systems, e.g. Li-ion, Li-S, Li-air, and all-solid-state Li batteries, rely on the use of solid-state ion conducting materials as electrodes and/or electrolytes. Continuous ion hopping from one mobile ion site to adjacent vacancy sites in a crystalline lattice forms the basis for ion conduction in solids. Atomic-scale factors, such as lattice structure and the concentration and distribution of mobile carriers and vacancies, decide the ion conductivity in solids, and thus dictate the rate capability and capacity in batteries.
