| Abstract | The performance of a catalyst enforced commercially available gas diffusion layer (GDL) electrode was evaluated at different discharge rates and depths in non-aqueous Li-O₂ batteries. The lead ruthenate (PbRuO) powder with a pyrochlore structure was employed as the catalyst. The lead ruthenate pyrochlore was prepared using a direct soft template method and characterized by X-ray diffraction (XRD), nitrogen physisorption techniques and transmission electron microscopy (TEM). The charge/discharge capabilities of the PbRuO/Ketjenblack (KB) composite were studied in tetraethyleneglycol dimethyl ether (TEGDME) containing 1M lithium triflate. The results show that PbRuO/KB can enhance the cell performance at high charge/discharge rates. Moreover, at a current density of 0.1mA/cm² it significantly increases the cell cyclability. With a cut-off capacity of 1000 mAh/g (PbRuO/KB only) the cell reached 100 cycles. As such, lead ruthenate has the potential to be used as an efficient bifunctional electrocatalyst for non-aqueous Li-O₂ batteries. |
