  1. Expected to optimize tradeoffs between mass energy density and thermal management and can be used as structural element. Common form factors are much smaller, relics of consumer electronic applications and less suited for large packs. Also Tesla is struggling with dry fabrication process as apposed to established wet with toxic solvent method, dry process supposed to dramatically reduce production line footprint, CapX and eventually accelerate production rate. Some 90% of wet process footprint is just for drying the cells and capturing solvent vapors. Naturally you'd expect fewer larger parts means fewer problems, better reliability. How it all pans out remains to be seen, Tesla continues to use multiple form factors but the semi and CT as well as structural batt pack Y's all require 4680s, a lot is riding on them.

  2.  @garethrobinson2275  Right. The question was why are they 'theoretically' better.
