The Inside Back Cover picture shows electrospun N‐doped carbon nanofibers encapsulating Co nanoparticles as an efficient oxygen reduction reaction (ORR) catalyst that can be considered for next‐generation metal–air batteries. Owing to the very unique nanostructure and composition, the ORR intermediates and electrons can easily access the active sites, leading to remarkably enhanced and stable ORR activities. More information can be found in the Full Paper by Z. Lu and co‐workers on page 1437 in Issue 9, 2016 (DOI: 10.1002/celc.201600275).
