Modular Lithium-Ion Cell Opening Approaches for an Automated Disassembly and Enhanced Recycling Efficiency

The increasing number of lithium-ion batteries currently being introduced to the market in Europe and worldwide raises the question of an efficient recycling approach for the valuable materials contained within. To further facilitate direct recycling approaches, the automated disassembly of batteries down to the electrode level becomes necessary. This research presents a modular approach to the opening and disassembly of pouch cell batteries. The study examines various methods for opening the cell housing and investigates and compares their effectiveness, precision, and impact on the recovered product. By evaluating different techniques, this research aims to identify the most efficient and reliable method to automatically open pouch type battery cells. In the comparison, factors such as the integrity of the recovered materials, the speed of the disassembly process, and the potential for automation will be considered. Once the optimal solution is identified, the research describes and implements the translation of this solution into an automated disassembly station. This involves designing and implementing a system that can open various battery cells consistently and accurately, ensuring that valuable materials are recovered with minimal loss or contamination. The modular nature of the approach allows for flexibility and scalability, making it adaptable to different types of batteries and varying production volumes. Overall, this research contributes to the development of sustainable recycling practices for lithium-ion batteries, addressing the growing need for efficient and environmentally friendly solutions.
