That, that, that is astonishing!
Precision in chemical engineering is always a hard problem, a problem I know that China struggles with. Chinese drug companies can't produce generic drugs with the same effectiveness. So poor Chinese people are forced to buy imports with sky high prices. The imprecision is the leading cause of battery cell quality problem.
I did not know everybody struggles with it. I suspect LG and Samsung are probably at the same level. I guess the 30% scrap rate is due to the fact that Tesla has a higher acceptance standard and pretty good quality verification system. Other EV builders are probably forced to eat the lower quality cells, leading to the low efficiency in their offerings.
As long as cells are safe, shouldn't Tesla install these less efficient/energy dense cells in large commercial power packs where space is not at a premium?
