Claim Text:
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.
