Tesla's Battery Evolution: 4680 vs 2170 Cell Comparison

Note: 2170 and 4680 refer to the dimensions of the cells 21mm diameter by 70mm length and are not model numbers

1 - How large and monolithic these packs are, and

2 - All that foam directly sprayed onto them.

Basically makes them uselessly unsalvageable
