title: High-rate oxygen reduction in mixed nonaqueous electrolyte containing acetonitrile.
abstract: A mixed nonaqueous electrolyte that contains acetonitrile and propylene carbonate (PC) was found to be suitable for a Li-O(2) battery with a metallic Li anode. Both the concentration and diffusion coefficient for the dissolved O(2) are significantly higher in the mixed electrolyte than those in the pure PC electrolyte. A powder microelectrode was used to investigate the O(2) solubility and diffusion coefficient. A 10 mA cm(-2) discharge rate on a gas-diffusion electrode is demonstrated by using the mixed electrolyte in a Li-O(2) cell.
