DIFFERENCE
DIFFERENCE is exploring new approaches to improve the disassembly and recycling of cell-to-pack battery systems. The focus is on laser-based separation methods, automated disassembly processes, and design modifications that make the dismantling of bonded and foamed battery architectures more cost-effective, safer, and more sustainable.
About the project
The DIFFERENCE project is investigating how modern cell-to-pack architectures can be efficiently disassembled and recycled at the end of their life cycle. The reason for this is that these battery systems contain various polymeric contaminants, such as thermally conductive adhesives, sealants, structural adhesives, and foams. These materials are important for structural integrity, insulation, and fire protection, but at the same time, they make disassembly considerably more difficult.
The project addresses precisely this challenge and develops solutions for the selective separation of adhesive, foam, and metallic components. It utilizes two laser systems designed to enable targeted processing of the various composite materials. This is complemented by an in-depth understanding of the C2P architecture to identify disassembly and recycling requirements at an early stage. In this way, DIFFERENCE combines battery design, laser technology, automation, and sustainability assessment into a unified research approach.

Aims of the project
The goal of DIFFERENCE is to further develop cell-to-pack battery systems so that they are not only high-performing during operation but also easier to disassemble and more suitable for recycling at the end of their life. To this end, design principles for “Design for Laser Disassembly” are being developed, which will enable future battery systems to be specifically tailored to automated separation and disassembly processes.
Another focus is on the development of a modular, robot-guided process chain for automated disassembly. This is intended to enable the reproducible, safe, and cost-effective processing of complex battery assemblies. In addition, the developed processes will be evaluated from both environmental and economic perspectives to assess their industrial feasibility and their contribution to a sustainable battery value chain. DIFFERENCE is thus part of the “B@ts” program for research and development in battery technologies aimed at creating a technologically independent, competitive, and sustainable battery value chain.

What do the project leaders have to say? The people who are shaping the future every day?
“Working within the ARENA2036 framework is particularly valuable because it brings together research, industry, and practical applications. For a project like DIFFERENCE in particular, this exchange creates the ideal setting for further developing innovative dismantling and recycling solutions in a practical manner.”
