It is an important goal to gradually substitute energy conversion based on fossil fuels by one that is based on regenerative energy sources. Consequently, electricity production will move from a centralized (one producer and many consumers) to a decentralized (many producers and many consumers) operation. Batteries play an important role in energy management. In this seminar the use of scanning probe microscopies will be shown for the investigation of battery materials and processes. The techniques demonstrated are AFM (Atomic Force Microscopy), STM (Scanning Tunneling Microscopy) and SECPM (Scanning ElectroChemical Potential Microscopy). All of them can be operated under in-situ electrochemical conditions. Examples will be given for the intercalation of Li-ions and Na-ions into graphite which happens to occur in the solvated state. Also, an example will be shown how using SECPM one can trace the potential distribution in the electrochemical double layer. The implications for the understanding of batteries will be discussed.



Ulrich Stimming is currently the Professor of Physical Chemistry at Newcastle University, United Kingdom. Previously, he was Head of the School of Chemistry at Newcastle University. He was CEO and Scientific Advisor and Principal Investigator of TUM CREATE in Singapore. He had a Chair of Technical Physics and was Professor of Chemistry at Technical University Munich (TUM). Prior to that he was a director at the Research Center Jülich and before, he served on the faculty of Columbia University in New York, U.S.A. He has visiting appointments at various universities including Shanghai Jiao Tong University (SJTU) and University of Science and Technology of China (USTC).

Currently, he is the director of the Northeast Centre of Energy Materials (NECEM) funded by EPSRC. He also co-directs a large battery project at Newcastle University on degradation of Li-Ion batteries in cooperation with Cambridge, UCL and Sheffield universities. A project on novel redox flow batteries is funded by industry. He has currently projects at Newcastle University based on funding of approx. 5 M GBP.

Prof. Stimming is the founder and Editor-in-Chief of the scientific journal “Fuel Cells-From Fundamentals to Systems”, VCH-Wiley. He was the co-director of the Joint “Institute for Advanced Power Sources” of TU Munich and Tsinghua University, Beijing, from 2010-2014. He coordinated for the Association of Leading Technical Universities in Germany (TU9) a research network on electro-mobility of a total of 8 universities in Germany and China.

Prof. Stimming was educated at the Free University of Berlin, Germany, where he received his Diploma in Chemistry and a Ph.D. in Physical Chemistry. He has 300+ publications, 20,000+ citations and an h-factor of 71; he also holds numerous patents and awards.
