help Tesla 4680 Battery Cell FAQ
Why is Tesla's 4680 cell called 4680?
The name comes from the cell dimensions: about 46 mm in diameter and 80 mm tall. Tesla introduced the format at Battery Day on September 22, 2020.
What is the tabless design in the Tesla 4680 cell?
Tesla described the 4680 as using a tabless electrode design to reduce electrical resistance and simplify current flow. That design was presented as one way to improve manufacturing and thermal behavior compared with older cylindrical cells.
Which Tesla vehicles use or were planned around 4680 cells?
Tesla connected the 4680 program to vehicles such as the Texas-built Model Y and Cybertruck. The cell is also part of Tesla's broader structural battery pack strategy.
How is the 4680 different from Tesla's 2170 cell?
The 4680 is physically larger than the 2170 cell used in many Model 3 and Model Y packs. Its larger format means fewer cells are needed for a pack, but manufacturing scale-up has been one of Tesla's major challenges.
