Electromobility is an important building block for a sustainable future and the careful use of environmental resources. But what happens to the batteries of electric vehicles when their original use ends? Instead of sending them straight to recycling, they can be reused in new applications. However, despite the high potential, upcycling is not yet widespread due to technical and economic hurdles.
An innovative project is dedicated to the challenges of quality control and residual value analysis of lithium-ion batteries. As part of a research project funded by the German Federal Ministry of Education and Research (BMBF), an interdisciplinary team is working on a method to determine the residual power and remaining service life of used lithium-ion batteries quickly, safely and non-destructively. This should enable reliable and economically viable secondary use of batteries. In the production of batteries, this method can be used in the final inspection. The cells can be classified by quickly and reliably assessing their quality: Whether they are suitable for use in electric vehicles or whether another application, such as battery storage, is an option.
This is where Sekels GmbH comes in: With our expertise in magnetic fields, we are working on a prototype for a magnetic shielding system, specifically designed for the quality control of lithium-ion cells.
