Experimental Thermodynamics and Phase Relations of New Anode Materials for Li-Ion-Batteries — •Hans Flandorfer, Klaus Richter, and Herbert Ipser — Institut für Anorganische Chemie / Materialchemie, Universität Wien, Wien, Austria

Li-Ion batteries have for long been recognized as an efficient way to store electric energy. For use in traction applications, however, these batteries have to meet several design criteria, such as number of charge/discharge cycles, energy density and safety.

The scope of SPP 1473 *WeNDeLIB* is the systematic investigation of materials interaction between the various materials used for cathode, anode, electrolyte and separators. The constitution of the relevant systems has been recognized as an important issue to understand the performance of the whole assembly.

Our Department has long lasting expertise in the field of phase diagram research and determination of thermodynamic properties. Together with other methods like EMF measurements and isopiestic vapor pressure measurements, all data required for thermodynamic modeling can be generated.

Our group will focus on the purely metallic anode materials. Co-Sn, Ni-Sn, Cu-Sn, and many others have been proposed as suitable materials. Thus, thermodynamics and phase relations of the respective ternary systems (Co,Cu,Ni)-Li-Sn will be investigated.
