Lithium flat cell.

Battery, especially flat cell

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.

Flat lithium cell

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.
