  • Publication number: 20170149106
    Abstract: A lithium-air battery is provided which includes a gas diffusion layer that is at least partially filled with air, having an electrically conducting material as a cathode, an at least partially electrolyte-impregnated filter having an electronically non-conducting material as a separator, and an anode having a lithium metal, a lithium-metal alloy or lithium-oxide-metal mixture. The separator is between the anode and the cathode and the electrolyte includes a hydrophobic, ionic liquid and a lithium salt. The three phases, gaseous air, liquid electrolyte and solid conducting material, are in contact on at least one point of the gas diffusion layer. A method for producing such battery and the use of such battery in a motor vehicle are also provided.
