The disposal of spent lithium-ion power batteries (LIBs) has become an important research topic owing to the booming market for electric vehicles. However, the recovery efficiency of the alkaline solution and organic solvent methods currently used to separate Al foil from cathode materials still has room for improvement.
However, the recovery efficiency of the alkaline solution and organic solvent methods currently used to separate Al foil from cathode materials still has room for improvement. The insufficient separation of Al foil and complexity of the battery types present obstacles to the extraction of valuable metals using simple processes.
Battery disassembly requires removing the plastic casing: automatizing partial disassembly (e.g., casing removal and cells recovery from battery packs) gave positive costs-benefits trade-off (Alfaro-Algaba and Ramirez, 2020); using a hybrid workstation (manually operated) resulted as best option for safety and costs (Tan et al., 2021). ... ...
To recycle high-value lithium-ion battery components, it is imperative to efficiently separate electrode materials from current collector foils and to separate cathodes from anodes. This study investigates the delamination behaviors of cathodes and anodes from their respective current collectors in aqueous media.
Disassembly tests were executed with the demonstrator. Findings proved that semi-automated disassembly of battery systems is feasible. They have developed a concept, i.e., a workstation for more flexibility, productivity, and safety in the disassembly of LIBs, at the module level. Figure 14.
As part of this direct recycling strategy, our proposed single-battery disassembly system has great potential to ensure the automatic separation of polymer-laminated aluminum films, separators, cathode sheets, and anode sheets with well-preserved integrity.
