The joint project DeMoBat aims to develop industrial disassembling processes for traction batteries and drive trains of electric vehicles. These processes are considered as a prerequisite for a resource-efficient and sustainable design of closed-loop supply chains for electro-mobility. Traction batteries represent a key cost factor of electro-mobility and cause significant environmental impacts during production, which is why their most efficient and long-term use is a crucial element of the sustainable design of electro-mobility.

The targeted disassembly of battery packs into individual modules and subsequent cell level enables condition-specific uses of the battery modules or cells. A disassembling allows on the one side reassembling for second use applications, such as energy storages or automotive spare parts. On the other side, high-quality recycling of the electrode active material can be reached. The same applies to electric motors, where the rare-earth permanent magnets and copper coils are valuable components.

While the other research partners are primarily working on technical solutions for disassembling, IIP is responsible for coordinating sub-project 1. In this context, IIP evaluates raw material markets, business models, legal framework conditions, and logistics concepts, as well as capacity and sequence planning of the disassembling processes from a technoeconomic perspective.
