A new design and synthesis of Fe 2 O 3 @C@MnO 2 nanocomposite via aerosol spray pyrolysis and electrodeposition is reported for application in rechargeable Li−O 2 batteries. Owing to the superior oxygen reduction/evolution reaction bifunctional catalytic activities attributed to the combined function of Fe 2 O 3 and MnO 2 and facile charge transfer in the carbon matrix, the nanocomposite exhibits long life, large capacity, and a small overpotential in Li−O 2 batteries.
