(Invited) What's New with Metal-Oxygen Batteries? a Multi-Scale Perspective

Metal-oxygen batteries continue to attract interest due to their high theoretical specific energies. However, several challenges must to be overcome before these batteries can be viable. For example, in the case of Li-O₂ systems a combination of sluggish charge transport within the Li₂O₂ discharge product and electrolyte decomposition at the electrolyte/Li₂O₂ interface have been proposed as limiting factors. This presentation will describe multi-scale computational studies aimed at revealing the mechanisms responsible for these limitations. Based on these findings, opportunities for improving cell performance will be discussed.
