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.

Abstract: A rechargeable electrochemical metal ion cell includes negative and positive electrodes, and an electrolyte system between them. The negative electrode includes a metal capable of releasing and accepting metal ions. The positive electrode includes at least one compound capable of releasing and accepting metal ions different from those of the negative electrode. The electrolyte system includes: a glycol-based electrolyte solution containing a salt of a metal included in the negative electrode and a salt of a metal included in the positive electrode; a matrix adapted to retain the electrolyte solution, where two reversible reactions take place simultaneously in the cell: a reversible deposition and dissolution process of ions of a metal included in the negative electrode takes place in the negative electrode and a reversible ion exchange process of a metal included in the positive electrode takes place in the positive electrode. The metals are different from one another.

Abstract: The present invention relates to a method for manufacturing a lithiated metal-carbon composite electrode, a lithiated metal-carbon composite electrode manufactured thereby, and an electrochemical device including the electrode. More particularly, the present invention relates to a method for manufacturing a lithiated metal-carbon composite electrode with a new structure having excellent charge/discharge and cycle characteristics, a lithiated metal-carbon composite electrode manufactured thereby, and an electrochemical device including the electrode. In the lithiated metal-carbon composite electrode, lithium is alloyed with a metal and is inserted into a crystal structure of carbon to form the composite having a stable structure. Thus, a volume of the metal is slightly varied, so a cycle characteristic may not be deteriorated and charge/discharge capacities may be improved.
