Abstract:
A battery comprises a plurality of individual cells whose poles are electrically interconnected with each other in series and/or in parallel and form a cell assembly. A sealing element is arranged at least in one edge region between the poles of adjacent individual cells.
Abstract:
A single cell for a battery includes an electrode foil stack situated in a housing formed from two enveloping metal sheets and a frame that electrically insulates the two enveloping metal sheets from one another. Current discharge tabs of electrode foils of one polarity are connected to one another to form a pole contact, and the respective pole contact is connected to an enveloping metal sheet, and an enveloping metal sheet in each case forms an electrical pole of the single cell. The current discharge tabs of the same polarity are led out in each case at a pole side of the electrode foil stack and connected to one another in a middle area of the pole side. The pole contacts are angled parallel to the pole side, in particular with respect to one-half of the particular pole side, and are connected to an enveloping metal sheet.
Abstract:
A battery is provided with a plurality of individual cells connected in series and/or in parallel to one another, and at least one cooling plate arranged on the pole side on the individual cells, with current drain tabs of electric poles of the individual cells being thermally coupled with the cooling plate and being angled such that they extend parallel to the cooling plate. Current drain tabs of adjacent individual cells are electrically interconnected in non-positive and/or in positive manner and pressed with the cooling plate in non-positive and/or in positive manner by clamping elements.
Abstract:
A single cell with a cell housing is provided. The cell housing is formed from two housing side walls and an electrically insulating frame arranged between them. An electrochemically active stack is arranged inside the cell housing, of which electrodes of equal polarity are electrically conductively connected to each other to form a pole. The poles are electrically conductively connected to one of the housing side walls. At least one of the housing side walls is formed to extend completely over an edge region of the frame, wherein the projecting region forms a cooling element.
Abstract:
A battery includes a stack of bipolar individual battery cells, each of which includes an electrode stack and two sheet metal covers bounding the individual battery cell at least in the stacking direction. The electrode stack is connected to at least one of the sheet metal covers by at least one weld. In the region of the at least one weld, the sheet metal cover welded to the electrode stack and/or the sheet metal cover of the adjacent individual battery cell in contact with the sheet metal cover is/are of a set-back design. As a result, the sheet metal covers of adjacent individual battery cells do not have any contact in the region of the at least one weld.
Abstract:
A battery has a heat conducting plate for temperature control, and a plurality of parallel and/or serially connected single cells which are thermally coupled to the heat conducting plate. A channel structure is arranged in the heat conducting plate for guiding a flow of a heat conducting medium therein, and connection cross sections for the channel structure extend from the heat conducting plate. In the region of the poles of the single cells the heat conducting plate has bores through which the poles of the single cells extend. An insert piece which is made from an electrically insulating material and is arranged around the pole of a single cell, at least partially abuts the outer surface of the pole, and has at least one spacer extending radially from the pole. The spacer is arranged in the region of the pole between the cover of the single cell and the heat conducting plate.
Abstract:
A single cell for a battery includes electrodes, preferably electrode foils, which are arranged within a cell housing. A current output lug is electrically connected to each electrode, and at least electrodes of opposite polarity are separated and electrically insulated from one another by a separator, preferably a separator foil. Current output lugs having the same polarity are electrically conductively connected to a pole, wherein the respective poles are guided from the interior of the cell housing to the outside. Each pole is electrically conductively connected to an electrically conductive area on an outer side of the cell housing, wherein the relevant two areas of different polarity are electrically insulated from one another. The pole lugs which are arranged on the relevant areas project in a free-standing manner out of the cell housing.
