I wonder if they will fit in the standard ultium module or if this is already the beginning of the end of the "upgradeable battery module"
Precisely. What the cells inside the battery are and what they conform to is essentially irrelevant to an Ultium vehicle. The modules are the modules and the only measure that even the service department is going to care about is whether the software is updated.I'm dubious as well, Hellsop. In China, GM has Ultium bricks that contain a rolled/folded cell rather than the flat "blade" pouch. So there is some flexibility to how the inside of the brick is laid out.
None of this makes InsideEVs alarmism and clickseeking any more legitimate, does it?I read the "original source". The operative word in that article is "was", as in General Motors WAS considering using cylindrical batteries.
