Disassembly of energy storage lithium battery module

How are retired lithium-ion batteries recycled?

The recycling of retired lithium-ion batteries (LIBs) involves typically pretreatments such as discharging, disassembly, shredding, separation, followed by pyrometallurgical or hydrometallurgical processes to recover active materials. These processes face substantial challenges in efficiently separating materials and achieving high purity levels.

What is a lithium-ion battery module?

An energy-storage system comprised of lithium-ion battery modules is considered to be a core component of new energy vehicles, as it provides the main power source for the transmission system. However, manufacturing defects in battery modules lead to variations in performance among the cells used in series or parallel configuration.

What are the key challenges in battery module disassembly?

The state of the art battery modules need to be analysed with regards to their structure, components and the relationship of the components to each other. In particular, the key challenges in battery module disassembly up to cell level are identified and classified in order to systematically derive the requirements for the disassembly system.

What is lithium-ion battery recycling?

Recycling lithium-ion batteries (LIBs) has gained prominence in the last decade due to increasing supply chain constraints for critical materials (such as lithium and cobalt) and policy shift toward increased circularity of materials to mitigate environmental concerns.

What are lithium-ion batteries & fuel cells?

Renewable energy storage devices such as lithium-ion batteries (LIBs) and fuel cells are key technologies. LIBs, in particular, play a central role in this transformative landscape, especially in electric vehicles (EVs) sector.

What makes disassembling battery housings easier?

All battery housings are assembled using screws which is beneficial for the disassembly since it is possible to remove the lid without damaging it. However, a large amount of screws is needed, making it a time-consuming activity and an increased number of parts results in longer lead times as well as higher material usage.
