Who Produces Tesla’s Lithium Batteries?

Tesla’s lithium batteries are produced through a combination of in-house manufacturing and partnerships with top global suppliers. Key battery production occurs at Tesla’s Gigafactories in the USA and Shanghai, China, with major suppliers like Panasonic, CATL, and LG Energy Solution enabling scalable, innovative lithium-ion battery production supporting Tesla’s electric vehicles and energy storage solutions.

What Role Do Chinese Manufacturers Play in Tesla’s Battery Supply Chain?

Chinese manufacturers, especially CATL and LG Energy Solution, are critical suppliers to Tesla’s battery ecosystem. Tesla’s Gigafactory Shanghai works closely with these factories, benefiting from China’s mature lithium-ion battery production clusters in Guangdong and surrounding provinces. This partnership delivers cost efficiency, rapid innovation, and high-volume supply crucial for Tesla’s international market expansion.

Which Tesla Gigafactories Produce Lithium Batteries and Where Are They Located?

Tesla’s principal lithium battery production occurs at Gigafactory Nevada (USA) with Panasonic, and Gigafactory Shanghai (China) where CATL and other suppliers produce cells and battery packs. Additionally, Gigafactory Texas is expanding production of Tesla’s new 4680 cells. These sites enable localized supply chains supporting Tesla’s global vehicle and energy storage production.

Why Does Tesla Produce Some Batteries In-House and Source Others from OEM Suppliers?

Tesla combines in-house battery cell innovation and manufacturing with OEM sourcing to balance cost, scale, and technology. Producing batteries internally, such as 4680 cells, drives proprietary advantages, while OEM partners like CATL provide volume production and specialized chemistries. This hybrid strategy helps Tesla stay competitive and meet increasing demand efficiently.

Who Are the Main OEM Lithium Battery Suppliers for Tesla?

Tesla’s main OEM suppliers include Panasonic (USA/Japan), CATL (China), and LG Energy Solution (South Korea). Each supplies specialized lithium-ion cells optimized for Tesla’s varying model needs. For example, CATL provides cost-effective LFP batteries for standard-range vehicles, while Panasonic focuses on high-energy nickel-based cells for long-range models.

When Did Tesla Start Producing Batteries in China, and What Is Its Impact?

Tesla began battery and vehicle production in China’s Gigafactory Shanghai in 2019. Since then, it has accelerated supply to Asian and European markets, reducing costs and delivery times. The Shanghai factory supports both vehicle assembly and production of battery packs, working with leading Chinese manufacturers to enhance Tesla’s global competitiveness and scale.

Are Tesla’s New 4680 Battery Cells Fully Produced In China or the USA?

Tesla’s 4680 battery cells are primarily produced at Gigafactory Texas and Nevada in the USA as of 2025. The Chinese operations still focus on traditional lithium-ion cells like LFP provided by CATL and others. Tesla is expanding 4680 production but currently relies on a mix of US in-house manufacturing and Chinese OEM supply for different cell types.
