High-Rate Oxygen Reduction in Mixed Nonaqueous Electrolyte Containing Acetonitrile
Journal Article
·
· Chemistry - An Asian Journal
A mixed nonaqueous electrolyte that contains acetonitrile and propylene carbonate (PC) was found to be suitable for a LiO2 battery with a metallic Li anode. Both the concentration and diffusion coefficient for the dissolved O2 are significantly higher in the mixed electrolyte than those in the pure PC electrolyte. A powder microelectrode was used to investigate the O2 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 LiO2 cell.
