Coating Thickness Measurement: Good Resolution Despite High Penetration Depth
Until now, either sensors with good signal penetration depth but low resolution or broadband terahertz sensors, which have very high resolution but only on thin layers with low absorption, have been used for quality control of battery electrodes.
The researchers at the Fraunhofer ITWM have now been able to combine the strengths of both processes in a new sensor technology. Together with the Fraunhofer Institute for Telecommunications HHI, they developed a »contact-free, high-resolution inline coating thickness measurement technology for highly absorbent materials« in the INTENSE project. The result is a demonstrator that will be used in the automotive industry following the successful project .
Digital Experiments in the Computer: Physical Simulation of LI-Ion Batteries
In the field of electromobility, the requirements for lithium-ion batteries are very high. Computer simulations help to assess the performance of potential new battery cells and to understand the microscopic relationships.
The Fraunhofer ITWM uses the »Battery and Electrochemistry Simulation Tool« BEST, a software environment for the physics-based, three-dimensional simulation of lithium-ion batteries. It is continuously being expanded and adapted to the individual needs of companies.
