Production Gigafactory 1
cylindrical cell (18650) prior assembly. several thousand of them form tesla model s battery.
cell level
the basis of energy storage system of tesla products lithium-ion cells in 18650 form factor. these cylindrical cells have diameter of 18 mm , 65 mm in length, size used batteries of laptops. cylindrical cells less expensive (costing 190–200 dollars per kwh of 2014) large format cells active layers stacked or folded (approximately 240–250 dollars per kwh).
the battery cells produced @ gigafactory of new form factor, larger 18650 cells used in model s , model x automobiles. while cells expected @ least 20 mm in diameter , 70 mm in length, revised specifications optimized form factor 21 mm (0.83 in) 70 mm (2.8 in). tesla refers 21-70 , whereas samsung refer size 21700 . panasonic expected begin cell production in 2016, , continue @ least 10 years. panasonic cells used in model 3. among machines spotted @ opening in july 2016 presses , rollers cathodes. gigafactory began mass production of 2170 in january 2017. tesla uses nickel manganese cobalt (nmc) lithium cells stationary storage (powerwall , powerpack), , nickel cobalt aluminum oxide (nca) vehicles.
product level
in october 2015, tesla moved tesla powerwall , powerpack production fremont factory gigafactory. tesla powerwall has been produced in finished portion since third quarter of 2015.
