Yep. Prismatic cells have poorer packaging-to-material ratio (circles are optimal). They offer better thermal properties, but thermals are not the main limiting factor anymore.
And the US automakers tried prismatic cells before. Chevy Volt used them in 2012!
How are circles optimal???
Circle packing = 90%
Blade battery packing = 100%
Chevy sells EVs with prismatic and pouch cells. I don't recall any they've widely sold that used cylinder cells. Most automakers use prismatic cells on their cars, even non-LFP variants.
