Abstract

Lithium–O2 batteries with a high energy density are promising power sources for electric vehicles. The article featured on the front cover reports novel RuO2 nanoparticles@La0.6Sr0.4Co0.2Fe0.8O3 nanofibers as efficient oxygen reduction reaction (ORR)/oxygen evolution reaction (OER) bifunctional catalysts and their excellent performance as a cathode catalyst for Li–O2 batteries. The improved performance is attributed to the superior catalytic activation of RuO2 nanoparticles toward OER. More information can be found in the Full Paper by C. Sun et al. on page 485 in Issue 7, 2017 (DOI: 10.1002/cnma.201700071).
