BMW tests sulfide-based solid-state cells in i7 prototype

Large-format, pure all-solid-state battery (ASSB) cells from Solid Power jointly developed with BMW have been integrated into an i7 test vehicle, which is currently undergoing trials in the Munich area. The concept battery integrated in the sedan combines Gen5 construction principles (prismatic cells in modules) with new module concepts for integrating ASSB cells.

ASSB technology promises higher energy density in a more compact storage system compared to current lithium-ion batteries.

The test program will focus on key technical challenges, including how to manage cell expansion, regulate operating pressure and optimize temperature conditions within the new battery system.
