Zinc–Air Batteries: Metallic Cobalt Nanoparticles Encapsulated in Nitrogen‐Enriched Graphene Shells: Its Bifunctional Electrocatalysis and Application in Zinc–Air Batteries (Adv. Funct. Mater. 24/2016)

On page 4397, Y. Li and co-workers demonstrate that metallic cobalt nanoparticles encapsulated within nitrogen-enriched graphene shells can be prepared using cobalt-containing Prussian blue as the single precursor. This facile method affords products with excellent bifunctional activity for both oxygen reduction and hydrogen evolution reactions. They can also be integrated into primary zinc–air batteries to enable high power density and long operation durability.
