Zinc-Air Batteries: Flexible Rechargeable Zinc-Air Batteries through Morphological Emulation of Human Hair Array (Adv. Mater. 30/2016)

Abstract

On page 6421, Z. Chen and co-workers describe an electrically rechargeable, nanoarchitectured air electrode that morphologically emulates a human-hair array for solid-state zinc-air batteries. Grown directly on a stainless-steel mesh, the hair-like array can effectively catalyze molecular oxygen to water. Batteries equipped with this electrode show tangible benefits, including improved flexibility and performance.

Keywords: bifunctional air electrodes; cobalt oxide; flexible zinc-air batteries; solid-state.
