Description
The BatUTA project aims to generate fundamental knowledge on the mechanical behavior of batteries and its interplay with electrochemical processes by advancing cutting-edge, non-invasive ultrasound technologies for characterization and inspection. This research is structured around three main strategic objectives: the development of novel contactless techniques, the study of the Mechano-Electro-Chemical (MEC) behavior, and the application of the resulting knowledge for advanced sorting and recycling.
Objectives
- Develop contactless ultrasound technologies: Investigate, develop, and optimize high-sensitivity, broad-band, air-coupled ultrasound techniques for in situ and in operando characterization of battery cells and components, ensuring high Signal-to-Noise Ratios (SNR) suitable for inline manufacturing processes.
- Study the Mechano-Electro-Chemical (MEC) behavior: Utilize ultrasonic waves to analyze the effect of electrochemical processes (like SOC/SOH changes, degradation, and failure) on the mechanical stresses within various battery technologies (including Li-ion and Solid State).
- Decouple information for sorting applications: Extract critical information from the ultrasonic "fingerprint" of batteries to enable agile methods for End-of-Life (EoL) sorting, thereby improving recycling and second-life applications.
