In Situ Analytical Electron Microscopy for Probing Nanoscale Electrochemistry

The use of in situ analytical electron microscopy for probing nanoscale electrochemistry enables us to understand dynamic changes in the chemistry and structure of bulk materials and interfaces over the course of electrochemical processes. Analytical transmission electron microscopy (TEM) has been used extensively to study electrode materials ex situ in the past. This article describes the use of a novel instrumental system that combines analytical electron microscopy with advanced spectroscopy to probe dynamic phenomena in an all solid-state battery. The intricacies of the experimental set-up are discussed, and the and in-situ results obtained at the nanometer scale are discussed.
