  text: Several problems arise at the O2 (positive) electrode in the Li-air battery,
    including solvent/electrode decomposition and electrode passivation by insulating
    Li2O2. 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.
