High Entropy Materials for Future Greener Batteries

The High Entropy Materials (HEM) concept is appealing because it opens additional possibilities for the materials designer to incorporate more of the periodic table, including environmentally green elements. By adjusting the elemental ratios as well as the elemental selection, the structural and functional properties of the material can be tuned to create a family of related HEM. Through deliberate synthesis and detailed characterization, then drawing correlations among HEM properties and resulting electrochemical behavior, structure-function dependencies can be revealed. This presentation will provide specific examples of understanding HEM properties for greener future batteries utilizing synchrotron-based spectroscopy and diffraction in concert with electrochemistry to characterize the materials changes under battery use.
