Abstract:
The stability of interfaces is an important parameter for all electrochemical devices. Advanced materials and systems rely on the spontaneous or artificial formation of stable interfaces that enable the functionality of bulk properties of materials. Thin layers homogeneously distributed on the active materials can enhance electron conductivity, improve thermodynamic stability or prevent undesired dissolution/degradation of the active materials. Stable interfaces can improve the utilisation of active materials and their long-term stability. With the request of having batteries with higher energy density (volumetric and gravimetric), we are exploring the possibility of using metallic lithium in combination with high-voltage cathodes. Since the operating voltage of both materials exceeds the thermodynamic stability, a thin and homogeneous coating should be applied. A strategy to improve the stability of high voltage cathodes with a thin layer achieved by a homogeneous distribution of conductive single ion polymer on the surface of NMC particles as well as a strategy to improve the stability of lithium metal will be discussed in this presentation.
