Electrochemical energy storage is a rapidly expanding area of study, driven by critical applications in alternative energy technologies (e.g. for grid storage coupled to intermittent solar/wind energy sources) and improved efficiency (e.g. in vehicle technology). Batteries, by their nature, do not operate under equilibrium conditions. Accordingly, there is a growing need for operando characterization tools to understand the dynamic mechanisms and kinetics of the electrochemical reactions which govern energy storage.
Within the NorthEast Center for Chemical Energy Storage (NECCES) EFRC, we are developing and applying a series of complementary operando tools to probe and decouple the structural, chemical, and electronic changes in operating batteries at the atomic-, particle- and electrode-levels. This will allow us to develop a comprehensive understanding of the fundamental processes that underlie performance limitations and failure. Methodologies span hard and soft X-ray scattering, spectroscopy and imaging, electron microscopies, and NMR-based spectroscopy and imaging.
