  • AIR CATHODE FOR AIR BATTERIES AND AIR BATTERY
    Publication number: 20160020469
    Abstract: An air cathode for air batteries, having excellent high-rate discharge performance, and an air battery comprising the air cathode, are set forth. The air cathode for air batteries uses oxygen as an active material and may be configured to form an air battery comprising the air cathode, an anode and an electrolyte layer present between the air cathode and the anode. The air cathode includes: a catalyst layer that contains at least an electrode catalyst and an electroconductive material; an oxide as the electrode catalyst, which is active against at least oxygen reduction reaction; and at least one kind of metal carbide as the electroconductive material, selected from a tungsten carbide, a titanium carbide and a molybdenum carbide.
    Type: Application
