Way out of his depth.


In fact, the gravimetric energy-density of the Model Y cell, which sits at 244.0 Wh/kg, is less than that of the Panasonic 21700 cell used in the Tesla Model 3 (253 Wh/kg). The modest decrease is attributed to the larger, heavier auxiliary safety components, and it must also be considered that the tabless design (and thus manufacturing remains at an early stage, compared to the mature Panasonic 21700 technology). We would expect further cell-level energy density enhancements before mass manufacture begins in September 2024.
