Tesla gets closer to volume battery cell production with 5-year lithium supply deal
Australian mining firm Piedmont Lithium announced on Monday that it has signed a five-year supply deal with Tesla. Under the terms of the two companies’ agreement, Piedmont would be supplying about a third of its planned 160,000-tonnes-per-year spodumene concentrate produce from its North Carolina mines to the American electric car maker.
In a press release, Piedmont noted that while its initial agreement with Tesla is set for five years, both companies have an option to extend the contract for another five years. The Australian mining firm added that while its initial agreement with Tesla represents about one-third of its North Carolina mine’s expected 160,000 tonnes per annum production, more lithium could be delivered to Tesla if needed.
Deliveries for Tesla’s lithium could begin between July 2022 and July 2023 based on the developmental schedules of Tesla and Piedmont. In a statement, Keith Phillips, the President and Chief Executive Officer of Piedmont Lithium, expressed his excitement about the Tesla deal. Phillips also noted that Piedmont will be accelerating its mining development in order to support Tesla’s plans.
“We are excited to be working with Tesla, which represents the start of the US domestic lithium supply chain and a disruption to the current value chain. The Agreement highlights the strategic importance of Piedmont’s unique American spodumene deposit and confirms the trend toward spodumene as the preferred feedstock for the lithium hydroxide required in high-nickel batteries.
“We will now accelerate our mine/concentrator development to support Tesla’s plans, work to further expand our mineral resources, and potentially increase our planned annual spodumene concentrate production capacity. We will simultaneously be advancing our plans to produce lithium hydroxide in North Carolina, using a combination of internally produced spodumene concentrate as well as material sourced from other producers around the world,” Phillips said.
The Tesla deal appears to have been appreciated by the Australian miner’s shares. Following its announcement, Piedmont Lithium’s shares experienced an 83% surge.
Tesla’s battery cell production initiative has captured the attention of the electric vehicle sector. During the company’s Battery Day event, Tesla outlined its cell production program, which involves a ground-up redesign of the batteries that are utilized for the company’s vehicles and energy storage products. The result of Tesla’s efforts was the Roadrunner cell, which adopts a 4680 form factor, allowing it to have 5x the volume of the 2170 cells used in the Model 3 and Model Y.
But for Tesla to attain its battery production goals, it would have to seal the deal with companies like Piedmont Lithium, which could supply the electric car maker with the necessary materials to produce battery cells. Previous reports have indicated that the company is already in the process of securing partners for its battery production push. Apart from Piedmont Lithium, for example, reports have indicated that Tesla is in talks with Canadian mining firm Giga Metals about the development of a low-carbon nickel mine, which will also be built in North America.

Tesla Full Self-Driving (Supervised) showed a record attach rate at delivery for new vehicles in the third quarter of 2026.
75 percent of new vehicle deliveries in North America included a subscription to FSD software, up from 55 percent in the prior quarter, a 20-percentage-point sequential gain in the company’s most mature market.
Tesla Q3 2026 Earnings results: in-line revenues, slight beat on EPS
Tesla shed light on the Q3 Shareholder Deck that 75 percent of new deliveries came with an FSD subscription:
“FSD (Supervised)⁴ attach rate continued to grow, reaching over 75% of new vehicle deliveries in North America – our most mature market – a nearly twenty percentage point sequential increase. We believe that FSD is driving demand in markets where it is available, and we continue to work with regulators to get it approved in other markets. “
The higher attach rate accompanied strong growth in the overall FSD consumer base, as active subscriptions rose to 1.75 million, a 67 percent year-over-year increase. For the first time, more than half of paid customers are on the monthly subscription, which is priced at $99 per month in the U.S.
People are buying FSD with a car attached, not the other way around
— Elon Musk (@elonmusk) October 21, 2026
The transition to subscriptions has accelerated since Tesla discontinued the one-time purchase option in most markets earlier this year. The recurring model improves revenue visibility and margins compared with large upfront payments. With three-quarters of North American deliveries now including FSD, the software is now an evidently large contributor to Tesla’s economics and ancillary revenue.
Geographic expansion remains important for further gains. FSD is now available in nine countries in the EU, and more than 100,000 customers have driven over 160 million kilometers. Tesla is pursuing broader EU-wide approval, with a related vote expected in December. Similar progress in additional markets could support higher attach rates beyond North America.
These results came as Tesla had a strong quarterly delivery performance of 486,532 vehicles in the quarter, which came with its largest passenger-vehicle backlog in four years. Battery supply continued to limit volume, but the company has pointed to FSD as a clear difference-maker that is helping sustain demand. As supervised capabilities improve, the attach rate will likely continue to improve.
At face value, it is a key measure of how Tesla is converting sales into autonomy progress.
Update: 10/22 10:51a – Para 1 consumers changed to “customers” for accuracy.
Tesla Cybercab units finally got a definitive date for when they will be able to be purchased by customers, ending speculation regarding whether the fully autonomous vehicle would be available in the near term.
During Tesla’s third-quarter 2026 earnings call on October 21, Vice President of Engineering Lars Moravy said the company is aiming to begin delivering its purpose-built Cybercab robotaxi to customers before year-end.
🚨 In short, Cybercabs are slated to go to customers by end of the year. All units are going into Robotaxi fleet currently, per @larsmoravy
Cybercab will be “transport-as-a-service,” but vast majority of Cybercab will be “Tesla-owned,” @elonmusk says https://t.co/R8Qu8QWdmp

“We’re trying to get Cybercabs to customers by the end of this year, 2026,” Moravy said. He added that production is underway on the line at Gigafactory Texas, but “all of those are currently going to our own internal Robotaxi fleet.”
Moravy explained that as operations scale, Tesla will “mainly deliver fully designed autonomous vehicles to our customers,” with the Cybercab as the first such vehicle. Initial customer deliveries will start small while the company gains experience with delivery logistics, ownership models, fleet management, and operating autonomous vehicles outside its direct control.
CEO Elon Musk reinforced the limited nature of private sales, describing the Cybercab primarily as a “transport-as-a-service” offering rather than a personal ownership vehicle like the Model 3, Model Y, or upcoming Roadster. “The vast majority of the Cybercab stuff will be Tesla-owned and transport-as-a-service,” Musk said.
The Cybercab is a two-seater vehicle developed by Tesla without a steering wheel or pedals. It relies completely on Tesla’s Full Self-Driving suite and has been in production since February. Early units have been put in Tesla’s Robotaxi service as of early September, when the company launched rides to the public. Tesla previously indicated it would aim to sell Cybercabs for about $30,000.
Unsupervised Full Self-Driving is expected to ship to consumer cars during Q2 2027, Ashok Elluswamy, Tesla’s Head of AI, indicated during the call. Early buyers or fleet operators may receive vehicles whose autonomous operation remains geographically restricted due to lagging regulatory agencies. There are some hurdles that remain ahead of Cybercab deliveries.

Major Takeaways
Full Self-Driving (Supervised)
“FSD (Supervised)⁴ attach rate continued to grow, reaching over 75% of new vehicle deliveries in North America – our most mature market – a nearly twenty percentage point sequential increase. We believe that FSD is driving demand in markets where it is available, and we continue to work with regulators to get it approved in other markets.”
Tesla Semi
“We began volume production of Tesla Semi, our Class 8 heavy-duty truck. The top variant can go 500 miles at full 82,000 lbs gross combination weight while achieving an efficiency of 1.7 kWh/mile. That efficiency allows the Tesla Semi to use a third of the energy used by a comparable diesel truck to haul the same payload. In a transportation market where energy is one of the largest components of total cost per mile, this will provide a meaningful advantage to Tesla Semi operators.”
SI Compute
“We plan to reach 400 MW of SI training compute by the end of the year, supporting the development of both vehicle and humanoid robot autonomy software. Additionally, we continued construction for the Austin Fab, where we plan to start commissioning equipment in 2027.”
Robotaxi
“We began deployment of Cybercab into our Robotaxi fleet in Austin. We reached nearly two million cumulative unsupervised miles for our Robotaxi service as of the end of the quarter. Operating hours in Austin are now 6am to midnight, and we expect to reduce wait times via increased fleet supply and improvement of Robotaxi orchestration algorithms. Grok is available in Cybercab with access to Grok Bot and Connectors, which allows users to manage their inbox, calendars, files, chats and tasks – all hands free via voice command – making Cybercab a mode of transport, a productivity space and, with our entertainment options, a second living room.”
