Tesla batteries are primarily made at several key Gigafactories around the world:

• Gigafactory Nevada (USA): Located in Storey County, Nevada, this is Tesla's first and largest battery factory, built in partnership with Panasonic. Panasonic supplies battery cells, which Tesla then assembles into battery packs for vehicles and energy storage products like the Powerwall. The factory produces lithium-ion battery cells, packs, and drivetrain components

• Gigafactory Shanghai (China): Tesla collaborates with Contemporary Amperex Technology Limited (CATL) here to produce lithium-ion battery cells and vehicles such as the Model 3 and Model Y. This factory serves the Asian market and helps streamline Tesla's supply chain in China

• Gigafactory Berlin-Brandenburg (Germany): This European hub manufactures Tesla battery cells and vehicles, supporting Tesla’s demand in Europe with sustainable energy practices and proximity to raw material suppliers

• Gigafactory Texas (USA): This site has ramped up production of Tesla’s new 4680 battery cells, which are crucial for upcoming vehicles like the Cybertruck. It complements battery production efforts in Nevada and Fremont

• Fremont Factory and Kato Factory (California, USA): The Fremont factory assembles vehicles and has pilot battery production lines, while the Kato Factory focuses on battery development and pilot production, including dry electrode technology innovations

Tesla sources raw materials globally, including lithium from Australia, South America, and North America, and partners with suppliers like Panasonic, CATL, and LG Energy Solution for battery cells. Tesla is also investing in lithium refining capacity in Texas to secure its supply chain

. In summary, Tesla's battery production is a global operation centered mainly in the USA (Nevada, Texas, California), China (Shanghai), and Germany (Berlin), combining in-house manufacturing with strategic partnerships to produce advanced lithium-ion batteries for its electric vehicles and energy products
