2. Major research programs involving phase diagram related research with
funding in Germany

German Research Foundation (DFG)
Priority Programme SPP 1473:
Materials with new design for improved lithium ion batteries – WeNDeLIB
Duration: 2010 + 6 years (review period 2 years)
Alloy and ceramic systems: LIB cathode and anode related systems.
Coordinator: Hans J. Seifert
The scientific work on the DFG Priority Programme 1473 – WeNDeLIB was started in
October 2010. 37 individual projects organized in Germany and Austria are
funded by the German Research Foundation
. Most of them are performed in the
frame of joint projects with three or more collaborating partners.

In the course of this programme the relationships between thermodynamics,
kinetics, crystal chemistry and micro-/nanostructures of materials for lithium
ion batteries
are scientifically investigated. This research aims at a better
understanding of active masses, electrolytes, current collectors and separators in
view of the entire cell system. Thermodynamic and kinetic models are combined in
this priority programme with experiments and analyses according to the best
practices in materials science.
The main topics of this programme are:
(1) materials and cell thermodynamics and kinetics
(2) heterogeneous equilibria and reactions
(3) innovative methods of preparation and synthesis of active materials
(4) electrochemical investigations combined with thermodynamics and constitution of
cell materials.
Thermodynamic and kinetic modelling and experiments are combined with advanced
methods for the preparation / synthesis and characterization of active materials. The
materials constitution, the thermodynamic stabilities of the functional crystal
structures and the phase transformations (in dependence of lithiation / delithiation,
grain size, temperature) are investigated in an integrated approach in this
The scientific objectives of this programme are:
- Materials thermodynamics and kinetics studies aiming at the provision of advanced active materials for lithium ion batteries of the next generation with comprehensively improved performance spectrum - Thermodynamic and kinetic modelling of the heterogeneous reactions, phase transformations and nano-/microstructure developments of the active materials which are required for high performance operation and control of degradation - Correlation of thermodynamic, kinetic characteristics with electrochemical and structural properties of the materials of the cell components - Improvement of the energetics and the thermodynamic safety of the entire system by specific design on the level of chemistry and materials constitution (heterogeneous phase assembly). The methods of Computational Thermodynamics (Ab initio, Calphad, Phase field, etc.) are used. In addition to standard polycrystalline materials, nanostructured and amorphous cathode and anode materials are prepared and their thermodynamic and electrochemical characteristics are measured. Additionally, of major interest are scientific results which can be derived from methods of thermal analysis, calorimetry (accelerating rate calorimetry; differential scanning calorimetry; solution and mixing calorimetry), Knudsen effusion mass spectrometry, high resolution electron microscopy and (in-situ, high temperature) X-ray diffractometry. The findings are correlated with results from electrochemical characterization. A three day workshop was organized in 2012 (February 21-23, 2012, Bonn). The project results for all 13 joint projects were presented by the young scientists (PhD students and Postdocs) and also some of the PIs orally presented. News on the organization of the SPP1473 and about LIBWorks were reported by the coordinator. In the late afternoon and evening, individual meetings of young scientists and PIs were organized to discuss new results, joint actions and next steps in work plan. 55 researchers attended and 35 presentations were given. A one-week workshop on the thermodynamics and heterogenous equilibria of lithium ion battery materials was organized 5-11 February, 2012. The meeting was held in the frame of the “International Seminars on Heterogeneous Multicomponent Equilibria” (Ringberg castle, Rottach-Egern). These annual one week seminars are organized by the Materials Science International Team, MSIT, Stuttgart, led by Dr. Günter Effenberg (winner of 2012 Hume-Rothery Prize from IOM3, UK). About 40 experts from academic institutions worldwide participate. One day of the seminar was dedicated to oral presentations by young scientists and PIs from SPP1473. 15 researchers from SPP1473 attended. Their newest results on LIB thermodynamics and materials constitution were presented and initiated very fruitful and advanced discussions most helpful for the research work of SPP1473. Additionally, over the whole week, materials systems relevant to SPP1473 were evaluated and their constitution and thermodynamics described. Evaluation Reports of the following battery relevant system were carried out in group works. The following systems were treated: A) Evaluation Reports submitted and accepted for publication in MSI Eureka Cu-Li-Sn Ringberg 2012/2013 - submitted (Hans Flandorfer, Siegfried Fuertauer, David Henriques, Dajian Li) Cu-Sn Ringberg 2012/2013 - submitted (Hans Flandorfer, Siegfried Fuertauer, David Henriques, Dajian Li) Fe-Li Ringberg 2009 - submitted (Lesley Cornish, Yann Eichhammer, Dmytro Pavlyuchkov, Elena Semenova) Li-O Ringberg2009 + Ringberg 2012 update - submitted (Artem Kozlov, Annelies Malfliet, Nathalie Lebrun, Petronela Gotcu-Freis) Li-Si Ringberg 2011 - submitted (M.

A summer school of 3 days length was held (September 05-07, 2012,
Romrod/Alsfeld). The organization of this event was strongly supported by the
Deutsche Gesellschaft für Materialkunde (DGM). At the beginning the coordinator
reported about the progress and news of the priority programme and on topics related
to thermodynamic modeling and experiments. PIs presented their major working
methodologies and relevant research results in their laboratories. Altogether ten
presentations of 90 minutes each were given. An external speaker (Dr. P. Masset,
Fraunhofer-Institut für Umwelt-, Sicherheits- und Energietechnik, UMSICHT;
Institutsteil Sulzbach-Rosenberg) reported on High Temperature Batteries. About 50
young researchers attended this summer school.
