Concurrent with yesterday's announcement that battery cell production is now underway at the Gigafactory, Tesla released this brief video that shows the 2170 battery cells running down the production line.
It's all-too brief and only shows a tiny portion of the production process, but at least it confirms that "mass" production of cells is indeed underway at the Gigafactory.
The cells seen in this video will be used in "Tesla’s Powerwall 2 and Powerpack 2 energy products.”
Starting in Q2 of 2017, battery cells destined to find a home in Tesla Model 3s will begin rolling down the line.
Then, by 2018, “the Gigafactory will produce 35 GWh/year of lithium-ion battery cells, nearly as much as the rest of the entire world’s battery production combined,” according to Tesla.
