  text: Rechargeable Li–O2 batteries have gathered enormous attention in the research
    community for having amongst the highest theoretical energy storage. Realizing
    the promise, even in part, in practice could produce a device that stores significantly
    more energy than other rechargeable batteries. Fundamental understanding of the
    reaction mechanisms is now realized to be key to overcome many challenges. We
    give a critical overview of the current understanding of the chemistry underpinning
    the Li–O2 cell with focus on the cathode and give a perspective on the most important
    research needs. Since performance and reversibility are often grossly misunderstood,
    we put emphasis on realistic performances to be achieved by Li–O2 cells and on
    means to identify reversibility. Parasitic chemistry is the foremost barrier for
    reversible cycling and now realized to be predominantly caused by singlet oxygen
    rather than by the previously thought superoxide or peroxide. This finding profoundly
    affects any other area of research from reaction mechanisms, to electrolytes and
    catalysts and dominates future research needs.
