Abstract

High-efficiency and low-cost electrocatalysts are generally believed to be the critical factor and have been highly researched to catalyze the oxygen reduction reaction (ORR) during the operation of Li-O₂ battery (LOB). The catalysts with better ORR performance are essential for high-performance LOBs. Herein, a binder-free MnO _x @carbon cloth cathode composed of Mn₃O₄ nanoparticles and Mn₂O₃ nanosheets were directly synthesized on the carbon cloth by electrodeposition and subsequently heat treatment at different temperature (from 200 °C to 400 °C). With the increase of temperature, the Mn₃O₄ nanospheres gradually transformed into Mn₂O₃ nanosheets. The MnO _x obtained at 350 °C exhibited the best ORR performance.
