Materials for energy conversion and storage increasingly rely on the 3-D characteristics of its microstructure and chemistry at the nanoscale.  This presentation will discuss the use of a synchrotron hard x-ray nanoprobe to measure the 3-D microstructural network, topology and elemental distribution in energy storage and conversion materials with high chemical sensitivity. Challenges and opportunities for future work will then be discussed. The goal of this research will be to obtain a scientific and engineering understanding into how microstructure-induced transport mechanisms govern performance.
