Battery cell with integrated sensor

Fraunhofer Institute for Silicon Technology ISIT, Dr. Andreas Würsig

At the Fraunhofer Institute ISIT, innovative methods for integrating various sensor systems directly into battery cells have been developed and validated within several funded projects. These include reference electrodes for separate potential measurement of anode and cathode, temperature sensors for detecting local hotspots, and pressure and strain sensors for analyzing mechanical changes within the cell structure. This integrated sensor technology enables significantly enhanced battery monitoring with high spatial and temporal resolution. Safety-critical conditions can be detected at an early stage, aging mechanisms can be precisely tracked, and operating strategies can be optimized. Furthermore, the generated data serve as a powerful development tool for improving cell design, material selection, and operational management of future battery systems.

Layer thickness measurement at various steps in the manufacturing process. Compared to indirect methods, direct terahertz layer thickness measurement is reproducible over time; it is not possible to lose the reference basis.

For optimal battery performance, the coating of battery foils must meet high requirements in terms of thickness and homogeneity. To conserve resources, quality should be checked as early as possible in the process.

With our layer thickness measurement systems, based on terahertz technology, anode and cathode foils can be examined for layer thickness distribution during the process – always contact-free and non-destructive. Direct layer thickness measurement is possible with measurement rates of several hundred measurements per second and a reproducibility of better than 1 μm. The measurement technology can be used in both dry and wet processes. 0

Snapshot from a foam encapsulation simulation for a module with cylindrical cells.

Both the designs of battery cells and their production processes are complex undertakings: The interactions of numerous parameters not only influence product quality in complex ways, additionally, due to complicated experimental diagnostics, it is often unclear why a particular process proceeds as observed or what are the reasons for certain limitations.

Suitable computer simulations can be valuable tools for addressing these questions. With its expertise in mathematical modeling and numerical methods, Fraunhofer ITWM develops customized, high-performance simulation tools for industrial applications in the battery sector: We present our BEST simulation tool for thermal-electrochemical cell design and analysis, as well as our CoRheoS platform, which can be used to simulate production processes such as electrolyte filling in cell production or foam encapsulation of cylindrical cells within modules.

Tubular energy system (TES)

Fraunhofer Institute for Structural Durability and System Reliability LBF, Eva-Maria Stelter

The tubular energy system (TES) is a lithium-ion-based energy storage system developed for particularly energy- and mass-critical applications, which differs significantly from conventional storage systems thanks to a number of innovative design features. Individual storage modules, constructed from 18650 cylindrical cells, have been fully integrated into the interior of a frame tube – designed as a central load-bearing structure – with a diameter of 80 millimetres. This eliminates the need for all components of the housing that would otherwise be required, as well as the parts needed for connection to the vehicle structure or for theft protection. The complete integration of the energy storage system into the interior of the circular tube creates excellent conditions for particularly effective air cooling via the internal tube flow using a small radiator-fan combination.

Laboratory Setup for ultrasound diagnostics for Lithium-Ion batteries.

Fraunhofer ISC in Würzburg is developing ultrasound diagnostic methods for the non-destructive examination of lithium-ion battery cells. The aim is to analyze material states and aging processes in order to enable reliable lifetime predictions. The method allows for a more accurate assessment of the cell’s state of charge and state of health during operation. At the same time, the mechanical diagnostics open up potential for optimized production processes, longer-lasting and more sustainable batteries, and, in the long term, new approaches to battery recycling.

CAD model of the lightweight battery housing trade fair demonstrator.

The COOLBat demonstrator shows how battery housings can be made significantly more climate friendly and more efficient through new design principles, materials, and manufacturing technologies. The focus lies on lightweight materials, functionally integrated structures, and resource efficient production. An electric vehicle battery system serves as the demonstrator to evaluate the developed solutions in terms of weight, functionality, and CO₂ performance. Integrating cooling channels into load bearing structures, energy absorbing aluminum foam sandwiches, tailored fiber composites, and novel thermal interface materials reduces mass, interfaces, and energy intensive joining steps. Continuous life cycle analyses enable CO₂ optimized material and technology choices throughout development. The results are transferable to many industries and are showcased in the demonstrator.

Sustainable Battery Design

Fraunhofer Institute for Structural Durability and System Reliability LBF, Eva-Marie Stelter and Dominik Spancken

The CIRCULUS battery features an innovative and sustainable mechanical design that aims to minimize its environmental footprint while ensuring maximum functionality. The demonstrator integrates key principles of lightweight engineering, circular economy, and sustainable material selection.

The design allows for easy disassembly and reuse of individual parts. This means that defective parts can be replaced without having to dispose of the entire system. Its accessibility and design for disassembly allow for subsequent use, for example as stationary storage or, at the end of its service life, even economic recycling of the plastics used.

These results were made possible through collaboration in the CIRCULUS project and were funded by the German Federal Ministry for Economic Affairs and Energy.
