Aren’t shaped prismatic cells the current state of the art anyway? The article mentioned BMW and Rivian using this size of cylindrical cell but I believe the latest from GM, Hyundai, and VW are all prismatic after the earlier designs were either pouch cells or cylindrical.

I guess it depends on who you’d ask. BMW made a switch from prismatic cells to cylindrical design only recently, and it looks like the biggest gain was in costs and weight efficiency. The range/capacity ratio didn’t improve that much. Although, to be fair, none of these parameters depend on battery alone.
