Disassembly methods of joints for circular battery packs (DIJON)

Purpose and goal

This goal of this project is to develop new joint design solutions, including disassembly and re-assembly methods which enable a circular flow of next generation’s EV battery packs. Today’s battery packs are joined with a combination of adhesive joints, mechanical joints, and thermal joints all with their pros and cons in terms of different properties such as performance, manufacturability, cost, etc.

Expected effects and result

The results from WP4 may be presented as an industrial demonstrator. Moreover, a summary of the joints that can be improved in terms of disassembly and re-assembly and the joints that are difficult to improve will be generated. The work will also include benchmarking of other commercial products.

Planned approach and implementation

In terms of the FFI research program’s objectives, the project contributes to strengthening the competitiveness of the Swedish automotive industry by developing sustainable concepts for joining, disassembly and re-assembly of EV battery packs, including suitable design solutions, to enable circularity. The project also contributes to production in Sweden by building deep and extensive knowledge of methods and technologies that lay the foundation for a circular material flow and automation solutions.
