Progress partially depends on exploring the basic electrochemistry of O2 reduction. Here we describe the effect of complexing-cations on the electrochemical reduction of O2 in DMSO in the presence and absence of a Li salt. The solubility of alkaline peroxides in DMSO is enhanced by the complexing-cations, consistent with their strong interaction with reduced O2. The complexing-cations also increase the rate of the 1-electron O2 reduction to O2•– by up to six-fold (k° = 2.4 ×10–3 to 1.5 × 10–2 cm s–1) whether or not Li+ ions are present. In the absence of Li+, the complexing-cations also promote the reduction of O2•– to O22–. In the presence of Li+ and complexing-cations, and despite the interaction of the reduced O2 with the latter, SERS confirms that the product is still Li2O2."}],"year":"2014","publication_identifier":{"issn":["1932-7447","1932-7455"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"None","page":"3393-3401","extern":"1","article_type":"original","status":"public","date_published":"2014-01-29T00:00:00Z","day":"29","publication_status":"published","date_created":"2020-01-15T12:17:28Z","publication":"The Journal of Physical Chemistry C","citation":{"apa":"Li, C., Fontaine, O., Freunberger, S.
