BMW Group and Solid Power have reached a significant milestone in their collaboration by integrating large-format, pure all-solid-state battery (ASSB) cells into a BMW i7 test vehicle, currently operating in the Munich area. This marks the first time ASSB technology is being tested on the road, highlighting its potential to offer higher energy density in a compact storage system compared to current battery technologies.
Since 2022, BMW and Solid Power have intensified their joint efforts to develop ASSB technology through a technology transfer agreement. The integration of ASSB cells into the BMW i7 combines proven Gen5 construction principles with innovative module concepts, aiming to achieve longer vehicle ranges without the added weight typically associated with current battery systems.
Solid Power’s CEO, John Van Scoter, expressed pride in the partnership, emphasizing the promise of ASSBs and the company’s commitment to advancing sulfide electrolyte innovation for the future of electric vehicles. BMW’s Vice President of Battery Cell and Cell Module, Martin Schuster, highlighted the company’s open-minded approach to technology development and the value of collaborations like the one with Solid Power in expanding their battery expertise.
