Title: Pt and Pd catalyzed oxidation of Li 2O 2 and DMSO during Li–O 2 battery charging

Rechargeable Li-O 2 and Li-air batteries require electrode and electrolyte materials that synergistcally promote long-term cell operation. We investigate the role of noble metals Pt and Pd as catalysts for the Li-O 2 oxidation process and their compatibility with a dimethyl sulfoxide (DMSO) based electrolyte. Lastly, we identify a basis for low potential Li 2O 2 evolution followed by oxidative decomposition of the electrolyte to form carbonate side products.
