  text: 'Rechargeable Li–O2 batteries have amongst the highest formal energy and could
    store significantly more energy than other rechargeable batteries in practice
    if at least a large part of their promise could be realized. Realization, however,
    still faces many challenges than can only be overcome by fundamental understanding
    of the processes taking place. Here, we review recent advances in understanding
    the chemistry of the Li–O2 cathode and provide a perspective on dominant research
    needs. We put particular emphasis on issues that are often grossly misunderstood:
    realistic performance metrics and their reporting as well as identifying reversibility
    and quantitative measures to do so. Parasitic reactions are the prime obstacle
    for reversible cell operation and have recently been identified to be predominantly
    caused by singlet oxygen and not by reduced oxygen species as thought before.
    We discuss the far reaching implications of this finding on electrolyte and cathode
    stability, electrocatalysis, and future research needs.'
