Materials for Electric Machines / Storage Systems
Benchmarking & System Evaluation
We analyse the requirements for components, materials and processes used in functional materials for energy technology, such as magnets for electric drives or lithium-ion batteries for energy storage in the consumer and automotive sectors. Here, we work with our customers to develop specific solutions. We contribute our scientific expertise to generate new insights, from the planning of analyses – including the definition of efficient methods – right through to the interpretation of results.

For the development and optimization of modern magnetic systems, we offer specialized analysis and evaluation of magnetic properties and relevant material characteristics. Depending on the specific problem, we employ numerical methods, process engineering considerations, the determination of characteristic magnetic parameters, and supplementary chemical analyses. Using quantitative microstructural analysis and machine learning methods, we assess material quality and specifically identify structure-property relationships.
Based on this, we develop high-performance hard and soft magnetic materials with customized properties, design complete magnetic systems, and create physically grounded micromagnetic models to provide a deep understanding of material and system behavior.

Right: Overview of the battery technology portfolio
For tear-down analyses (TDA) and characterization of lithium-ion batteries of all common cell formats, as well as fuel cells, we offer customized analysis packages tailored precisely to your requirements. Our portfolio includes non-destructive CT analyses (geometry and cell design), cell tear-downs to assess manufacturing quality and identify defects, detailed benchmark analyses (including mass balances and bill of materials), determination of compositions and active materials, post-mortem analyses to investigate aging effects and damage analyses, as well as electrical characterizations of batteries and battery modules.
With our comprehensive range of services, we help you ensure the quality and performance of your batteries. You benefit from state-of-the-art high-performance microscopy, our many years of expertise in the preparation and handling of lithium-ion batteries, and our proprietary machine-learning-based analysis methods. For sensitive samples, we guarantee oxygen-free sample transfer to ensure the highest precision and safety. Our investigations reliably support you in the development of your products and processes, the selection of suitable suppliers, the inspection of incoming goods, and the detailed investigation of the causes of damage. Trust our expertise for precise analyses and well-founded results.
