6 FAQs about [Battery pack laser disassembly method]
How do you design a battery pack?
When designing a battery pack, it is important to weigh different parameters against each other to acheive a suitable design. It is therefore significant for these tradeoffs to have a valid foundation to stand on. One tradeoff that needs to be accounted for is comparing safety of the battery against its weight.
Do batteries need to be disassembled?
The batteries need to be disassembled for remanufacturing up to the cell level, as shown in this work. However, there are some technical challenges in this disassembly operation. Examples on how to overcome these challenges are:
What are the ablative and cutting processes of battery packs?
The cutting processes are primarily focused on the dismantling of metal and metal-plastic components of battery packs. Furthermore, in the ablative processes, the ablation of active material of the battery electrode foil using ns-pulsed lasers is investigated.
Can laser batteries be recycled in a fast loop?
These enormous quantities of vehicle batteries must be recycled in a fast loop due to the increasing shortage of critical raw materials. Laser technologies offer the possibility to perform many of the necessary process steps of dismantling and recycling.
How can automated disassembly be introduced in the future?
Once the production of batteries has increased, automated disassembly can be introduced in the future. For this to be possible, it is important to consider the design of the battery and to make sure it has a minimized amount of materials and parts, in addition to suitable joining techniques.
Can laser technology be used in cutting and ablating processes?
Laser technologies offer the possibility to perform many of the necessary process steps of dismantling and recycling. In this paper, an application overview and analysis of laser technologies in the field of cutting and ablating processes will be presented.
