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.
- New method shows how molecular switches are influenced by their neighborsResearchers at Friedrich Schiller University Jena and the Helmholtz Centre Berlin (HZB) have, for the first time, been able to directly observe how the environment surrounding a molecular switch influences its electronic structure. Molecular switches are molecules that can be switched between two states by external influences such as changes in temperature—similar to a switch with the positions »On« and »Off«. Such molecules are being investigated as potential building blocks for future data storage devices or sensor materials. Using magnetic-field-dependent terahertz spectroscopy, the researchers have now, for the first time, been able to distinguish whether neighbouring molecules in a material are in the same or different states. The results have been published in the journal »Angewandte Chemie International Edition«.
- 3D magnetic field experiment at BESSY II takes spintronics a step further(Fe0.63Ni0.3Pd0.07)3P or FNPP is a magnetic material that exhibits complex magnetic structures even at room temperature. This makes the material of interest for spintronics, a field that could enable data processing with significantly lower energy consumption. One potential application is novel magnetic memory devices. However, generating and modifying the desired structures in a controlled manner remains a challenge to date. A new study led by HZB has now taken a step forward in this regard. They demonstrated at the worldwide unique VEKMAG-Station at BESSY II, that a tiny external B-field in the plane of the magnetic patterns is sufficient to change them.
- Detailed insights at BESSY II into the oxidation processes of copperBefore pure copper oxide builds up, complex superstructures such as ‘29’CuxO, are formed. The new results on the '29' CuxO superstructure have relevance for catalyst research and corrosion protection in the development of safe copper containers for nuclear waste repositories.
