The DeMoBat joint project involved the development of functions and tools for the automated disassembly of battery modules and electric drive units. In addition to the construction of three functional demonstrators for the dismantling of battery systems, the dismantling of battery modules and the dismantling of drive units, digital twins were created that allow in-depth analyses and simulation of the processes and can determine the battery condition. The project also investigated under what conditions and in what proportions active material components recovered during the recycling of a battery cell can be reused in the production of new battery cells.
DeMoBat is explicitly geared towards industrial application. The overall project, in which 12 partners from industry and science are working together, is divided into three sub-projects. Sub-project 1 forms the thematic superstructure and embeds dismantling in the context of a circular economy, taking market economy aspects into account. Sub-projects 2 and 3 deal with the automated dismantling of batteries and electric drive units, the components of electric cars with the greatest individual values. The results are an important contribution to increasing sustainability in the field of electromobility, to securing important raw materials and to strengthening Germany as a business location. The results have already been taken up by the industry for concrete implementation.
