Review of the year - TUM.Battery, one year online

Almost one year ago on 22.01.2019 TUM.Battery went online. Thanks to the good preparatory work of the then 8 partner chairs, a website was completed and launched in a very short time with the aim of making the competences and research activities of the TUM scientists in the field of battery research visible to the outside world. Today, after more than one year of cooperation in the TUM.Battery network, we can look back on a very successful time - besides the numerous publications and project starts, the interdisciplinary exchange and cooperation on working level between the chairs could be intensified. In addition, the following highlights from the year 2019 can be reported:

The chairs are working on 22 ongoing projects in the field of battery research:

  • ASSB Bayern: All Solid State Battery
  • ExZellTUM III
  • e-conversion
  • EffSkalBat
  • EvaBatt
  • Everlasting
  • HighSafe
  • LiSi
  • NOVBATCON
  • OparaBatt
  • Open_BEA
  • ProFeLi
  • ReVISEDBatt
  • StorageLink
  • SmartB4P
  • ProZell-Projekte
  • Cell-Fill
  • Sim4Pro
  • MiKal
  • ProfiStruk
  • ExZellBattMat
  • iMoBatt
  • KlemA
  • InnoCase

Project highlight:

ExZellTUM III: After the successful completion of the first two phases ExZellTUM I & II, the TUM.Battery colleagues - within the competence cluster for battery materials (ExcellBattMat) - deal with the material, chemical and electrochemical characterisation and analysis as well as the modelling of anode and cathode materials for lithium ion cells of the next generation. The project is funded by the Federal Ministry of Education and Research (BMBF) with a total funding volume of € 4.2 million.

Further highlights:

Institute for Machine Tools and Industrial Management (iwb) focuses on battery production
The iwb was expanded by the research team "Battery Production". This will bundle and further expand competence in battery research. Battery cells have been researched at the iwb since 2010. In 2014, a complete research production line for lithium-ion cells was set up in this context. This set the course for research in the field of battery production at the TUM. Starting in July 2019, the new Topic Group for Battery Production with 11 employees will focus on the same goals that the German government is pursuing - strengthening tomorrow's battery research and production.

Battery Discussions 2019 at the TUM
During the two days of the conference about 120 participants - among them many scientists of the TUM.Battery Group - attentively followed the lectures of the 18 invited international speakers, renowned experts in their field.The focus of this year's symposium was on various aspects of solid state electrolytes, which are a promising candidate for next generation batteries due to their increased safety and performance potential.

TUM wins poster award of the 7th Battery Forum 28 January 2019
At this year's Battery Forum in Berlin, the poster prize went to the Technical University of Munich. Robert Morasch from the Chair of Technical Electrochemistry won the prize of 1.000€ for his contribution Detection of Binder Migration using Impedance Spectroscopy and its Influence on the Tortuosity of Li-Ion Battery Electrodes.

Publications:

Over 40 scientific papers were published by TUM.Battery members in 2019. In the current Journal of Electrochemical Society (ECS) Ranking (as of November 2019) 8 papers published in the ECS of the TUM.Battery Chairs Prof. H. A. Gasteiger, Prof. A. Jossen and Prof. G. Reinhart were among the 50 most read in the field of batteries and energy storage.
