Here is a very interesting video of a Tesla 4680-type cylindrical battery cell teardown, presented by The Limiting Factor, in partnership with a team from UC San Diego.
As we know, the 4680-type (46 mm in diameter and 80 mm tall) is the latest and the biggest cylindrical cell for Tesla EVs (see more about Tesla batteries here), currently used in the Made-in-Texas (MIT) Tesla Model Y.
