The Cover picture shows an electric car powered by a
Li–O
2 battery driven on a road. The road is covered with graphene, which imp
lies that the Li–O
2 battery is supported by an air cathode catalyst composed of oxide nanofibers/nanoparticles attached onto graphene. The small yellow balls are RuO
2 nanoparticles whereas the black wires are LaMnO
3 nanofibers acting as efficient catalysts for discharging/charging battery. The big yellow balls represent
lithium ions, red balls are oxygen molecules, and the gray rocks on the nanofibers are so
lid reaction products (Li
2O
2). More details can be found in the Full Paper by Yoon et al. on
