Abstract
Battery-powered electromobility is essential for achieving the climate goals set out in the Paris Climate Agreement. Using recycled materials is important not only because of the high carbon footprint of virgin materials, but also because of supply chain dependencies. In the automotive traction battery recycling process, the disassembly step is crucial for reusing components and recovering recyclates with high purity. Therefore, this paper will comprehensively analyze the different disassembly technologies for end-of-life electric vehicle batteries on the basis of a systematic literature review. The analysis will address non-destructive, semi-destructive and destructive disassembly technologies as well as supporting technologies such as artificial intelligence and vision systems. In addition, the advantages and challenges of the different technological approaches and the disassembly process itself will be discussed. Ultimately, implications for policy makers and industry players will be highlighted to facilitate the entire value chain of automotive traction battery recycling with robust disassembly technologies.
