A lithium-air battery is provided, which includes a cathode having a gas diffusion layer containing a solid electronically conductive material coated with carbon black, the gas diffusion layer being at least partially filled with gaseous air, a separator having an electronically nonconducting filter material arranged between the anode and the cathode, the filter material being at least partially impregnated with a liquid electrolyte, and an anode containing a material selected from lithium metal, material alloyable with lithium, metal oxide, and mixtures thereof. Methods for making such battery and the use of such battery in a motor vehicle are also provided.

Low-polarization lithium oxygen battery

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.
