Approach

Design Analysis of representative battery systems w.r.t materials, joining techniques, sub-assemblies, parts and geometries.
Hazard analysis: Identification of chemical, electrical, mechanical hazards, safety-critical boundary conditions and influencing variables in the handling and processing of functional units.
Process Definition: systematical examination and assessment of suitable separating production processes according to DIN 8580 of the functional units of a traction battery, namely
- pack,
- module and
- cells taking into considerations time/costs, safety and environmental aspects, etc. with focus on mechanical separation.
Evaluation Methods and Criteria: Identifying universal methods to assess the state of the battery and it’s functional units in terms of
- SOC, state-of-charge,
- SOS, state-of-safety and
- SOH, state-of-health as a decision basis for reuse/refurbish/remanufacture/recycling.
Demonstrator: Feasibility study at laboratory level on the separation.
LCA and TCO: Assessment of the potential environmental and energy impacts of the different recycling processes through Life Cycle Assessment and Total Cost of Ownership.
Eco Design: Recommendations for Design for Disassembly for the future design of battery systems allowing for improved recycling processes
