Abstract
Official abstract text for this publication.
To provide a cell connector for the electrically conductive connection of a first cell terminal of a first electrochemical cell and a second cell terminal of a second electrochemical cell of an electrochemical device, which allows a reliable and fail-safe connection of the cell terminals, it is proposed that the cell connector comprises a first contact section for connection to the first cell terminal, a second contact section for connection to the second cell terminal and an elastically and/or plastically deformable compensation region, which connects the first contact section and the second contact section to one another and allows a movement of these contact sections relative to one another.
First claim
Opening claim text (preview).
The invention claimed is: 1. Electrochemical device comprising at least a first electrochemical cell with a first cell terminal, a second electrochemical cell with a second cell terminal and a cell connector connecting the first cell terminal and the second cell terminal electrically conductively to one another, wherein the cell connector comprises a first contact section for connection to the first cell terminal, a second contact section for connection to the second cell terminal and a deformable compensation region, which is disposed between and connects the first contact section and the second contact section to one another and which is more elastically and/or plastically deformable than the first contact section and the second contact section to allow a movement of the first contact section and second contact section relative to one another, wherein the electrochemical device comprises a receiving device for receiving the first electrochemical cell and the second electrochemical cell, wherein the receiving device is configured as a cooling body surrounding the first electrochemical cell and the second electrochemical cell and is formed from a first material consisting of a metal or alloy that has a first coefficient of thermal expansion, and wherein the cell connector comprises a base body, which is formed from a second material that has a second coefficient of thermal expansion, which differs by less than 10% from the first coefficient of thermal expansion of the first material. 2. Electrochemical device according to claim 1 , wherein the electrochemical device is configured as an accumulator. 3. Electrochemical device according to claim 1 wherein the deformable compensation region includes a profiling different. from that of the first contact section and that of the second contact section to render the deformable compensation region more elastically and/or plastically deformable .than the first contact section and the second contact section. 4. Electrochemical device according to claim 1 wherein the deformable compensation region comprises a material having a mechanical property that renders the deformable compensation region more elastically and/or plastically deformable than the first contact section and the second contact section. 5. Electrochemical device according to claim 1 wherein the first material and the second material are substantially the same. 6. Electrochemical device according to claim 1 wherein the first material and the second material are aluminum or an aluminum alloy.
