Manganese oxide/carbon composite nanofibers: electrospinning preparation and application as a bi-functional cathode for rechargeable lithium-oxygen batteries

Abstract

Manganese oxide/carbon composite nanofibers are fabricated via an electrospinning technique. The electrospun composite nanofibers show an excellent catalytic performance for oxygen reduction and evolution, leading to reduced discharge-charge overpotentials and improved cycling properties of a Li-O-2 battery with a hybrid electrolyte.
