I'd really like to know how using round cross section cells pack more energy density in a given volume than rectangular ones, since circles don't fit together without gaps. I can only think that the energy density of a cylindrical cell is enough to overcome this. The article doesn't explain this critical point, though.
The shift to cylindrical battery cells, and away from the rectangular-shaped prismatic batteries it currently uses, follows a similar move by rival Tesla Inc (NASDAQ:TSLA). Supporters of cylindrical batteries say its format - which is larger than prismatic batteries - can raise energy density and, in turn, be more cost-effective.
