Abstract

A new design and synthesis of Fe2O3 @C@MnO2 nanocomposite via aerosol spray pyrolysis and electrodeposition is reported for application in rechargeable Li-O2 batteries. Owing to the superior oxygen reduction/evolution reaction bifunctional catalytic activities attributed to the combined function of Fe2O3 and MnO2 and facile charge transfer in the carbon matrix, the nanocomposite exhibits long life, large capacity, and a small overpotential in Li-O2 batteries.
