    MORE SUSTAINABILITY IN ELECTROMOBILITY THROUGH APPLICATION OF NEW METHODS TO IMPROVE BATTERY SERVICE LIFE | In the Fraunhofer Attract project "ProLIBs: A Battery Cell ID Card", the service life of batteries for electric vehicles and other applications is predicted and improved. The new method for lifetime prediction is based on a combination of measurements of battery properties and models of battery cell behavior. These measurements can be made directly while a battery is in use, for example, in an electric car. By applying this method for more accurate lifetime prediction of high energy lithium ion battery cells and other cell types such as solid-state batteries in the battery management system (BMS), it is possible to achieve increased lifetime with optimal charge and discharge profiles.

    Gentle and environmentally friendly decoating of electronic components

    The aim of the Rapid-KI project is to develop control concepts for the local decoating of encapsulated or protective-coated electronic components. For this purpose, sensor data are collected, evaluated by means of AI and used for a highly dynamic real-time control of the laser processes in order to enable innovative recycling and repair concepts. The high flexibility and scalability of the laser technology also allows subsequent transferability of the development to a wide variety of application fields, e.g. decoating in the wind energy sector, ship, rail and aircraft construction as well as repair applications in the field of e-mobility.

  • POWDER TECHNOLOGY AS A SUSTAINABLE ALTERNATIVE TO CONVENTIONAL MANUFACTURING PROCESSES | Scarcity of raw materials and increasing environmental pollution pose major challenges to today's world. This makes the sustainable, resource-saving manufacture of products all the more important. The entire product life cycle must be considered: From design through manufacturing and logistics to recycling. Powder technology offers the best prerequisites here. It allows material and energy consumption to be significantly reduced and raw materials to be easily recycled. Fraunhofer IFAM has been working on various processes of powder technology for many years.

    Manfred Peschka (left) and Prof. Dr. Ingo Grunwald (right) have developed mediNiK®, a medical hydrogel, for the removal of kidney stones.

    Kidney stones are painful and can be life-threatening. They are shattered with a laser and the fragments are then removed with a grasper. If the fragments are too small, they cannot be grabbed and remain in the kidney, leading to the formation of a new kidney stone. Purenum GmbH, a spin-off from Fraunhofer IFAM, has developed a medical hydrogel to market maturity aimed at tackling this issue.

    HOW TO AVOID GALVANIC CORROSION? | Galvanic corrosion, also called bimetallic corrosion or dissimilar metal corrosion is not a new phenomenon: Even in ancient times, it was found that copper nails used to fasten lead sheets to ship hulls corroded more quickly. Although this phenomenon has been known for centuries, this form of corrosion continues to cause damage and accidents. The experts at Fraunhofer IFAM can support in risk assessment and the selection of protection methods.
