Ag decorated α-MnO2 nanorods are studied as a cathode catalyst for rechargeable lithium-oxygen battery (LOB). The composites are synthesized by in-situ composite technique in the presence of polymeric additives and characterized by SEM, XPS, and FT-IR. The battery with Ag decorated α-MnO2 nanorod composite electrode shows an initial discharge capacity of 793 mA hg-1(electrode), with reversible charge capacity of 778 mA hg-1(electrode), while battery with only α-MnO2 has discharge capacity of 510 mA hg-1(electrode) and charge capacity of 504 mA hg-1(electrode). No Li2O or Li2O2 can be detected after discharge and Li2CO3 is the main discharge product, which suggests that the decomposition of organic carbonate electrolyte occurs during discharge.
