Maybe they have the best energy density per cell, but you leave a lot of empty space between the cells. I doubt it ends up being more dense

Hexagons would pack better, but I'm not sure that the marginal gain (if any) in energy density would offset the increase in manufacturing complexity.

Also, if any pressure were to build up in a non-cylindrical cell, it would be prone to bulging, possibly damaging its neighbouring cells.

Tesla do per-cell cooling and the round shape offers more surface area for that

A cylinder has the least surface area per unit volume of any extruded shape

Generally that's true, but in this case it's about a flat surface vs curved

That still doesn’t change anything, unless tesla is only cooling one side of the cell for whatever reason
