  text: The short history of research on Li-O2 batteries has seen a remarkable number
    of mechanistic U-turns over the years. From the initial use of carbonate electrolytes,
    that were then found to be entirely unsuitable, to the belief that (su)peroxide
    was solely responsible for degradation, before the more reactive singlet oxygen
    was found to form, to the hypothesis that capacity depends on a competing surface/solution
    mechanism before a practically exclusive solution mechanism was identified. Herein,
    we argue for an ever-fresh look at the reported data without bias towards supposedly
    established explanations. We explain how the latest findings on rate and capacity
    limits, as well as the origin of side reactions, are connected via the disproportionation
    (DISP) step in the (dis)charge mechanism. Therefrom, directions emerge for the
    design of electrolytes and mediators on how to suppress side reactions and to
    enable high rate and high reversible capacity.

  text: Singlet oxygen (1O2) formation is now recognised as a key aspect of non-aqueous
    oxygen redox chemistry. For identifying 1O2, chemical trapping via 9,10-dimethylanthracene
    (DMA) to form the endoperoxide (DMA-O2) has become the mainstay method due to
    its sensitivity, selectivity, and ease of use. While DMA has been shown to be
    selective for 1O2, rather than forming DMA-O2 with a wide variety of potentially
    reactive O-containing species, false positives might hypothetically be obtained
    in the presence of previously overlooked species. Here, we first give unequivocal
    direct spectroscopic proof by the 1O2-specific near infrared (NIR) emission at
    1270 nm for the previously proposed 1O2 formation pathways, which centre around
    superoxide disproportionation. We then show that peroxocarbonates, common intermediates
    in metal-O2 and metal carbonate electrochemistry, do not produce false-positive
    DMA-O2. Moreover, we identify a previously unreported 1O2-forming pathway through
    the reaction of CO2 with superoxide. Overall, we give unequivocal proof for 1O2
    formation in non-aqueous oxygen redox and show that chemical trapping with DMA
    is a reliable method to assess 1O2 formation.
