All-Solid-State Battery Cells are tested in a BMW i7

23 May 2025, 14:37:35

All-Solid-State Battery Cells are tested in a BMW i7The BMW Group is bringing large-format, pure ASSB cells from Solid Power to its test vehicle, a BMW i7, which is being operated in the Munich area. The potential benefits of ASSB technology: higher energy density in a very compact storage system compared to current technologies.

The concept battery integrated in the BMW i7 test vehicle combines proven Gen5 construction principles (prismatic cells in modules) with new, innovative module concepts for integrating ASSB cells from Solid Power. The management of cell expansion will be investigated here. The use of solid power cells with sulfide-based electrolytes and their complete integration into a battery pack will provide the BMW Group with further important findings in the test program over the coming months.

The innovative cells were developed and manufactured by Solid Power in collaboration with experts from the BMW Group. Further development steps are required to implement ASSB technology in a competitive overall storage system. The BMW Group and Solid Power have been cooperating since 2016 through an extended "Joint Development Agreement", which was supported by BMW Group's investment in Solid Power in May 2021 as part of a financing round. At the end of 2022, BMW and Solid Power agreed to further deepen their partnership. BMW will operate a solid cell prototype line at the CMCC (Cell Manufacturing Competence Center) in Parsdorf on the basis of a research and development license and using the experience and expertise of Solid Power.
