The amount of energy that can be stored in Li-ion batteries is insufficient for the long-term needs of society, for example, for use in extended-range electric vehicles. Here, the energy-storage capabilities of Li–O2 and Li–S batteries are compared with that of Li-ion, their performances are reviewed, and the challenges that need to be overcome if such batteries are to succeed are highlighted.
