The analysis highlights that a complete automatic disassembly remains difficult, while human-robot collaborative disassembly guarantees high flexibility and productivity. The paper introduces guidelines for designing a robotic cell to disassemble a battery pack with the support of an operator.
Current battery packs are not designed to be disassembled, spaces between modules are narrow, and joint technologies are mostly irreversible (e.g., glued parts, welded plates, one-way screws), bringing to a difficult non-destructive disassembly.
The methodology involves upfront consideration of analysis paths that will be conducted on the exposed internal components to preserve the state (operational or failed) of the battery. The disassembly processes and exposures must not alter the battery materials once they are removed from their hermetically sealed containers.
Following the recommendations given after the safety analysis, as a specific potentially explosive atmosphere (ATEX) 3 zone, the battery pack was manually disassembled. The manual disassembly brought to a disassembly procedure which was decomposed and analysed to identify how to automate the same operations with a robot.
As reported in , even using modules with a limited residual charge, thermal runaway, with gas emission, is possible in case of short circuits that can easily happen during the disassembly. The gas mixture released from LiB can create an ATEX zone around the battery pack.
The techno-economic assessment of automated battery pack disassembly shows that automation can indeed decrease costs compared to manual disassembly. This, in turn, might lead to reduced gate fees paid to off-set expenses of the recycling facility or, in the best-case result, in a profitable EV battery recycling process.
