Scientists Meet Scientists – TUM-IAS Wednesday Coffee Talk : “Nanoscale Visualization of Internal Battery Processes using Quantum Sensing” by Dennis V. Christensen
Events, WCT |

On 19 November 2025, Dennis Valbjørn Christensen (Department of Energy Conversion and Storage, Technical University of Denmark) will talk about “Nanoscale Visualization of Internal Battery Processes using Quantum Sensing”.
Abstract: Battery development pivots around understanding the complex processes governing battery operation and degradation. Battery degradation often links structural and chemical inhomogeneities with strongly heterogeneous carrier transport at the nano- and microscale, which remains challenging to resolve with current operando imaging techniques. Here, I present how quantum sensing can be used to examine the charge and discharge cycles in lithium and post-lithium batteries. Through imaging ionic and electronic current distributions and probing the associated chemical reactions at the nanoscale, valuable insights into battery inhomogeneities and degradations can be gained. The approach facilitates spatially resolving heterogeneous redox reactions, buried current distributions, and mechanistic contributions to dendrite formation in batteries.

THE TUM-IAS WEDNESDAY COFFEE TALKS
Every Wednesday after lunch, it's all about a new topic - current research highlights at TUM, insights into the work of our Fellows from all over the world, sometimes even topics not usually found at TUM, such as history or theology.
The talks held online start every Wednesday during TUM lecture time at 13:00 CE(S)T. Everyone is welcome - TUM researchers of all levels, students, visiting scholars, and anyone interested!
