Abstract: A method for utilizing the inner energy of an aquifer fluid includes geothermal thermal water mixed with gas and optionally crude oil in a closed cycle to obtain an environmentally-neutral, carbon-dioxide-free utilization of the aquifer fluid and an environmentally-friendly supply of electric and thermal energy. An aquifer fluid is removed from an aquifer by means of a removal device, gas is separated by degassing the aquifer fluid in a gas-separation device, optionally crude oil is separated if necessary, the heat energy of the thermal water is utilized in at least one system for utilizing the thermal energy, the extracted gas and the optionally separated crude oil is com busted in at least one combustion device and the inner energy of the gas is utilized by operating a generator, the CO2 being removed from the waste gas and recycled into the aquifer.

Abstract: Battery, especially flat cell, comprising an electrode of lithium-metal or lithium-alloy, an electrode containing an active material intercalating lithium ions, a separator between both electrodes, and a housing enclosing the electrodes and the separator with connector tabs for both electrodes, wherein at least one of the electrodes (1; 2; 3) is a multi-layer body built by multiple folds and an equal layer-thickness of the active material (4; 12; 13) between the folded layers.

Abstract: Lithium flat battery consisting of a first housing part accommodating a first thin-layer electrode, a second housing part accommodating a second thin-layer electrode, and a separator placed between the electrodes, wherein the housing parts of the battery are built of electrically conductive, wherein the separator presents electrically insulating sealing and bonding material in the area where both housing parts are in contact with each other and wherein the housing parts are united by the sealing and bonding material on the separator thus forming through him a closed housing.
