MUNICH: The BMW Group is bringing large-format, pure ASSB cells from Solid Power to a tester BMW i7 in Munich.
The potential benefits of ASSB technology: higher energy density in a very compact storage system compared to current technologies.
Since 2022, the BMW Group and Solid Power Inc have intensified their activities for the development of all-solid-state battery (ASSB) technology.
“We believe in the promise of ASSB’s and continue to drive innovation of our sulfide electrolyte in support of that future for EV’s,” said Solid Power president and CEO John Van Scoter.
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 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.
Since 2008, the BMW Group has been steadily expanding its expertise in the area of battery cell technology.
Since 2019, this know-how has been bundled at the BMW Group's Battery Cell Competence Center (BCCC) in Munich.
The BCCC covers the entire value chain, from research and development to battery cell design and production capability.
