Who makes the cells.

Tesla's longest-standing cell partner. Panasonic supplied 18650 cells for the Model S and Model X from its Japanese plants and produces 2170 cells inside Gigafactory Nevada for Model 3 and Model Y packs assembled there.

Supplies nickel-rich 2170 cells (NMC) for Long Range and Performance Model 3 and Model Y built in Shanghai and Berlin. Spun off from LG Chem in December 2020.

Supplies prismatic lithium iron phosphate (LFP) cells for rear-wheel-drive Model 3 and Model Y. Tesla's first LFP cars rolled out of Giga Shanghai in late 2020.

BYD's Blade LFP cells were used in a structural pack for the rear-wheel-drive Model Y built at Giga Berlin from 2023.

Designs and assembles its battery packs and, since 2022, manufactures its own 4680 cylindrical cells in Fremont (pilot line) and at Gigafactory Texas.
