Tianqun Wang was born in the Inner Mongolia region of China. After earning her master’s degree in medicinal and biological chemistry from the University of Edinburgh, she pursued a PhD at the University of Bonn. Tianqun joined the research group of Prof. Barbara Kirchner in August 2024.
What are you working on within Ecobat?
The focus of my research is to develop improved simulation methodologies to reduce the experimental workload. As part of the Ecobat project, I am investigating how ions in the battery’s electrolyte solution interact, examining their coordination, transport properties, and ionic conductivity. I achieve this through detailed analysis of simulations. Currently, I am working with systems based on calcium tetrafluoroborate and plan to expand this research to mixed-anion systems. The ultimate goal is to optimize the solid electrolyte interface (SEI) using mixed-anion electrolytes, paving the way for more efficient and high-performing batteries.
What would be an ideal electrolyte for a modern battery?
An ideal electrolyte would have minimal ion pairing, ensuring high ion mobility and increased ionic conductivity. Another critical property is electrochemical stability during oxidation and reduction, which creates a so-called window of electrochemical stability—essentially, the upper and lower limits of applied potential. My current research focuses on exploring various concentrations of solvents and salts to create the optimal mixture for enhanced battery performance.
How do you stay motivated to do research?
It’s common in research for things not to go as planned. However, when experiments or simulations don't work out, it often sparks new ideas, and that’s what keeps me motivated. The prospect of discovering something new and getting closer to the truth is always exciting. Each setback is an opportunity for fresh insights.
How do you recharge?
When I encounter difficulties in my research, I often seek advice from my colleagues. They are a great source of support and encouragement, and talking things through with them helps me regain focus and energy.
Another way I recharge is through travel. I love experiencing beautiful scenery, as it helps me reconnect with nature and de-stress. Since moving to Germany, I’ve already visited several places around Bonn, and I plan to explore even more. My next weekend getaway will be a trip to Mainz, which I’m really looking forward to.
What do you like in Germany?
I used to live in Shanghai, which is a megalopolis with a fast-paced lifestyle. In contrast, Bonn feels much more relaxed and cozy, which I really appreciate. I also love German architecture—there’s a charm to it that’s very different from what I’m used to. However, I’m still adjusting to German food; it's quite different from the variety of flavors I'm used to back in China!
