Prof. Dr. Yan Lu: Developing new types of batteries sustainably
Since 2009, Yan Lu is a researcher at the Helmholtz-Zentrum Berlin. In 2017, she became a professor at the University of Potsdam and at HZB. In addition to her work at the HZB, she is now also a professor at the University of Jena. © M. Setzpfandt / HZB
Yan Lu is appointed new Professor of Hybrid Materials for Electrochemical Energy Storage and Conversion at Friedrich Schiller University Jena together with HZB. Congratulations!
“Conventional lithium-ion batteries are very powerful, but also expensive, as they require metals such as nickel and cobalt in addition to lithium,” says chemist Prof Dr Yan Lu. “That’s why I’m researching more sustainable alternatives, such as lithium-sulphur batteries and batteries based on hybrid materials,” explains the 47-year-old scientist, who is working at Friedrich Schiller University Jena since this semester. Her work combines various areas of expertise: In order to make energy available electrochemically, she combines organic and inorganic chemistry, for example, and also draws on research methods from biochemistry.
As part of her joint appointment with Helmholtz-Zentrum Berlin (HZB), where she continues to head the Institute for Electrochemical Energy Storage, the new professor is also co-director of the Helmholtz Institute for Polymers in Energy Applications Jena (HIPOLE Jena), which has been founded in 2023 in Jena by the university and HZB.
About Yan LuAfter studying chemistry in Shanghai, Yan Lu completed her doctorate at TU Dresden and then conducted research first in Bayreuth and from 2009 at the Helmholtz Centre Berlin. In 2017, she became a professor at the University of Potsdam and at HZB. In addition to her work at the Helmholtz Centre, she has also been Professor of Hybrid Materials for Electrochemical Energy Storage and Conversion at the University of Jena since the winter semester 2023/24.
- Fascinating archaeological find becomes a source of knowledgeThe Bavarian State Office for the Preservation of Historical Monuments (BLfD) has sent a rare artefact from the Middle Bronze Age to Berlin for examination using cutting-edge, non-destructive methods. It is a 3,400-year-old bronze sword, unearthed during archaeological excavations in Nördlingen, Swabia, in 2023. Experts have been able to determine how the hilt and blade are connected, as well as how the rare and well-preserved decorations on the pommel were made. This has provided valuable insight into the craft techniques employed in southern Germany during the Bronze Age. The BLfD used 3D computed tomography and X-ray diffraction to analyse internal stresses at the Helmholtz-Zentrum Berlin (HZB), as well as X-ray fluorescence spectroscopy at a BESSY II beamline supervised by the Bundesanstalt für Materialforschung und -prüfung (BAM).
- Element cobalt exhibits surprising propertiesThe element cobalt is considered a typical ferromagnet with no further secrets. However, an international team led by HZB researcher Dr. Jaime Sánchez-Barriga has now uncovered complex topological features in its electronic structure. Spin-resolved measurements of the band structure (spin-ARPES) at BESSY II revealed entangled energy bands that cross each other along extended paths in specific crystallographic directions, even at room temperature. As a result, cobalt can be considered as a highly tunable and unexpectedly rich topological platform, opening new perspectives for exploiting magnetic topological states in future information technologies.
- MXene for energy storage: More versatile than expectedMXene materials are promising candidates for a new energy storage technology. However, the processes by which the charge storage takes place were not yet fully understood. A team at HZB has examined, for the first time, individual MXene flakes to explore these processes in detail. Using the in situ Scanning transmission X-ray microscope 'MYSTIIC' at BESSY II, the scientists mapped the chemical states of Titanium atoms on the MXene flake surfaces. The results revealed two distinct redox reactions, depending on the electrolyte. This lays the groundwork for understanding charge transfer processes at the nanoscale and provides a basis for future research aimed at optimising pseudocapacitive energy storage devices.
