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.
- Battery research with the HZB X-ray microscopeNew cathode materials are being developed to further increase the capacity of lithium batteries. Multilayer lithium-rich transition metal oxides (LRTMOs) offer particularly high energy density. However, their capacity decreases with each charging cycle due to structural and chemical changes. Using X-ray methods at BESSY II, teams from several Chinese research institutions have now investigated these changes for the first time with highest precision: at the unique X-ray microscope, they were able to observe morphological and structural developments on the nanometre scale and also clarify chemical changes.
- BESSY II: New procedure for better thermoplasticsBio-based thermoplastics are produced from renewable organic materials and can be recycled after use. Their resilience can be improved by blending bio-based thermoplastics with other thermoplastics. However, the interface between the materials in these blends sometimes requires enhancement to achieve optimal properties. A team from the Eindhoven University of Technology in the Netherlands has now investigated at BESSY II how a new process enables thermoplastic blends with a high interfacial strength to be made from two base materials: Images taken at the new nano station of the IRIS beamline showed that nanocrystalline layers form during the process, which increase material performance.
- Hydrogen: Breakthrough in alkaline membrane electrolysersA team from the Technical University of Berlin, HZB, IMTEK (University of Freiburg) and Siemens Energy has developed a highly efficient alkaline membrane electrolyser that approaches the performance of established PEM electrolysers. What makes this achievement remarkable is the use of inexpensive nickel compounds for the anode catalyst, replacing costly and rare iridium. At BESSY II, the team was able to elucidate the catalytic processes in detail using operando measurements, and a theory team (USA, Singapore) provided a consistent molecular description. In Freiburg, prototype cells were built using a new coating process and tested in operation. The results have been published in the prestigious journal Nature Catalysis.
