| Research Abstract |
Lithium/air secondary batteries are the best candidate for a power source for electric vehicles, because of their high specific energy density. We focused on an aqueous lithium/air system because of the promising performance. A water stable and water penetration free high lithium ion conducting solid electrolyte sheet was prepared and combined with lithium metal and solid polymer electrolyte to form the hybrid water stable lithium anode, which enabled the high power density and good cycle performance. In parallel, we tried to find the catalysts for reduction of both oxygen molecule and OH- ion. Some perovskite oxides were effective to suppress the oxidation of carbon supporting materials.
