摘要： A method for producing a battery includes depositing, via sputter deposition, a coating on at least a portion of a cup shaped first housing part of the battery. The coating includes aluminium, chromium, tin, and/or an alloy having two or more of the group consisting of aluminium, chromium, and tin. The method also includes establishing an electrical connection between a current conductor of the battery and the cup-shaped first housing part of the battery and assembling the cup-shaped first housing part of the battery and a second housing part of the battery to form a housing of the battery. The housing has an interior space that includes a composite body including a positive electrode, a negative electrode, a separator, and the current conductor. The cup-shaped first housing part has a circular or oval bottom and a ring-shaped side wall.

摘要： A method of producing an electrode-separator winding includes feeding a first current collector, feeding a second current collector, feeding two separators in strip form to a winding device, and winding the first and second current collectors and the separators to form a winding with a sequence, wherein a contact strip is welded on at least one of the contact sections of the current collectors, or at least one of the contact sections is folded over to form a contact strip, and at least one of the separators is reinforced in at least one risk region in which the at least one separator within the completed electrode-separator winding lies against the at least one contact section in which the contact strip is welded on or against the at least one contact section folded over to form a contact strip.

摘要： A button cell includes a housing having a metal cell cup and a metal cell top. An electrode winding disposed within the housing is formed from a multi-layer assembly that is wound in a spiral shape about an axis, the multi-layer assembly including a positive electrode formed from a first current collector and a negative electrode formed from a second current collector. A separator is disposed between the electrodes. The first current collector includes a first end section bent so as to extend out of the electrode winding forming an uncoated first flat layer adjacent to the electrode winding. An insulator is positioned (i) between the first flat layer and the first end side of the electrode winding or (ii) between a second flat layer and a second end side of the electrode winding.

摘要： A battery has a prismatic metal housing that includes a rectangular base having a base inner side and a base outer side, a rectangular cover having a cover inner side and a cover outer side, the size and shape of which substantially correspond to that of the base, and four rectangular side elements connecting the base and the cover and each have an inner side and an outer side. The at least one individual cell is a winding having a first and a second end face and the first end face faces in the direction of the base and the second end face faces in the direction of the cover. Conductor vanes electrically connect to the base of the metal housing exit from the first end face. These are fixed to an electrically conductive collecting and positioning means inserted into a receiving means in the base of the metal housing and fixed therein.

摘要： An electrochemical cell that generates hydrogen has an anode including an electrochemically oxidizable substance and an electrode designed for hydrogen generation as a cathode and an aqueous alkaline electrolyte. The anode and the cathode are designed such that the hydrogen generation begins at the cathode as soon the anode and the cathode are electrically connected to one another. At least one resistance foil is adhesively bonded to at least one outer side of the housing which, when it is connected as a load resistance between the anode and the cathode, reduces the current flow between the anode and the cathode and therefore also the gas generation rate.
