The invention relates to electrochemical cells of a rechargeable battery. It is the object of the invention to provide possibilities with which parameters can be determined simply, reliably and with sufficient spatial resolution within the cells of a rechargeable battery in real time and with small additional technical effort. In an electrochemical cell in accordance with the invention, at least one sensor element is arranged within the cell, integrated therein. In this respect, a sensor element is configured as an electrically conductive layer-wise conductor track structure on a surface of a dielectric laminate configured in the form of a thin film. Except for regions arranged at the outer margin provided for an electrical contacting, the conductor track structure is sealed in a fluid-tight manner by a further dielectric laminate which is configured in the form of a film and which is arranged on the conductor track structure.
