Disassembly Automation for Recycling End-of-Life Lithium-Ion Pouch Cells

Abstract

Rapid advances in the use of lithium-ion batteries (LIBs) in consumer electronics, electric vehicles, and electric grid storage have led to a large number of end-of-life (EOL) LIBs awaiting recycling to reclaim critical materials and eliminate environmental hazards. This article studies automatic mechanical separation methodology for EOL pouch LIBs with Z-folded electrode-separator compounds (ESC). Customized handling tools are designed, manufactured, and assembled into an automatic disassembly system prototype that consists of three modules. Verification experiments utilizing dummy cells prove that the main components of pouch LIBs (cathode sheets, anode sheets, separators, and polymer-laminated aluminum film housing) can be automatically separated and extracted with well-preserved integrity using our proposed disassembly strategy.
