Abstract

Rechargeable Li-O₂ and Li-air batteries require electrode and electrolyte materials that synergistically promote long-term cell operation. In this study, we investigate the role of noble metals Pt and Pd as catalysts in the Li-O₂ oxidation process and their compatibility with dimethyl sulfoxide (DMSO) based electrolytes. We identify a basis for low potential Li₂O₂ evolution followed by oxidative decomposition of the electrolyte to form carbonate side products.
