Energy storage disassembly mis

What is repurposing as a building energy storage system?

Repurposing as building energy storage systems is an energy-efficient and environmentally friendly way to second-life electric vehicle batteries (EVBs) whose capacity has degraded below usable operational range e.g., for electric vehicles.

How to design a battery disassembly system?

The design of the disassembly system must consider the analysis of potentially explosive atmospheres (ATEX) 1 of the area around the battery pack and, if necessary, adopt tools enabled to work in the corresponding ATEX zone.

Can a battery pack be disassembled?

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.

Are battery pack designs a key obstacle to automated disassembly?

As identified in various studies, a key obstacle is the significant variation in battery pack designs, which complicates the automation process . Thompson et al. highlighted that the diversity in battery pack designs, along with the use of various fixtures and adhesives, impedes automated disassembly.

What happens if a Lib battery is disassembled?

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.

What is uneven distribution in battery disassembly?

Uneven distribution is tackled in considering the processing of multiple batteries between multiple disassembly cells, also introducing into the problem the associated risk to each process from the level of deformation of the battery components.
