【 摘 要 】

Abstract

Trilayered Pd/MnO_x/Pd nanomembranes are fabricated as the cathode catalysts for Li-O₂ batteries. The combination of Pd and MnO_x facilitates the transport of electrons, lithium ions, and oxygen-containing intermediates, thus effectively decomposing the discharge product Li₂O₂ and significantly lowering the charge overpotential and enhancing the power efficiency. This is promising for future environmentally friendly applications.
