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.
