The development of advanced lithium and post lithium (Na-, Mg-, …) batteries requires an integrated understanding of the materials electrochemical properties, their thermodynamics and kinetics behavior and relationships to thermal and safety performance. This symposium will focus on both the individual properties of advanced lithium and post lithium battery materials and the behavior of the active materials within operating cells and batteries. Besides the materials electrochemical, thermodynamic and kinetic data, their heterogeneous phase reactions are of interest. Additionally, contributions are invited considering micro -and nanostructure properties and crystal chemistry of electrode materials e.g. related to environmental conditions and cell operation modes. Presentations will cover recent results from experimental investigations, theoretical approaches and simulations (ab initio, calphad, phase field, …).
