Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The Cover picture shows</bold> a possible solution to the low round‐trip efficiencies of Li–O₂ batteries (the most promising next‐generation battery) owed to the poor reversibility of the formation of the discharge product Li₂O₂ and the associated high polarization potentials. This can be achieved by controlling the phase structure and morphology of Li₂O₂. By embedding Co nanoparticles in carbon nanofibers, a uniform film‐like amorphous Li₂O₂ is formed and both the charge and discharge overpotentials are decreased. More details can be found in the Full Paper by H.‐T. Kim et al. on <bold>page 2496 in Issue 15, 2015</bold>.
