Executive Summary

Understanding structure-composition-property-performance relationships is fundamental in developing more powerful, long-lived, and affordable lithium-ion batteries. Raman Imaging and Scanning Electron (RISE) microscopy is an extremely useful technology for investigating the compositions of battery electrodes at the nanoscale. By utilizing integrated Raman microscopy and SEM within a common vacuum chamber, researchers can quickly visualize structural and chemical information acquired from the battery’s internal components, such as molecular composition, grain fractures, and degradation processes at the electrodes. Here we show how RISE microscopy can document changes in new and used electrodes and provide insight to aid the development of batteries with greater longevity.

Learning Outcomes:
