Description
Summary:Accurate in situ monitoring of crucial parameters like temperature and pressure lead to a better understanding of processes that occur in a battery through its lifetime and therefore accelerate the development of new technologies in the battery market. This paper presents an integration scheme for ultrathin temperature and pressure sensors on a flexible sheet using common thin-film processing. The sensors cover the specific detection ranges (up to T = 80 °C, p = 1.5 MPa) and sensitivities for the envisioned application. Furthermore, it is shown that the dedicated encapsulation and flat topology do not influence the electrochemical performance of the battery cell.
