Lithium-ion battery systems are a key to sustainable electromobility. The increasing number of lithium-ion battery systems on the market also requires highly efficient product and material cycles. Remanufacturing, i.e., the industrial reprocessing of battery systems for reuse in the same application, is a promising way of conserving resources before repurposing in further applications or material recycling that destroys the product.
In the University of Bayreuth sub-project, mechanical-electrical-constructive system analyses are carried out to approach essential findings for the remanufacturing of lithium-ion battery systems. The results of these analyses will be compared with the procedural requirements of circular economy options of reuse. Constructive obstacles to remanufacturing are then identified, and approaches to solutions for a future battery system design are derived.
