Tesla battery supplier for China starts mass production of Model 3 batteries: sources
Industry sources have suggested that LG Chem, a company reportedly tapped by Tesla as one of its battery suppliers for its Shanghai-based factory, has begun the mass production of 2170 cells for the Model 3 in its Nanjing factory.
According to South Korean tech publication THEELEC, LG Chem is producing NCM 811 battery cells for the electric car maker, which features a nickel proportion of 80% or more. Prior to its reported contract with Tesla, LG Chem has used its NCM 811 cells for electric buses. The Model 3 will then be the first sedan that will use these specific, LG-made cells.
The industry sources claimed that LG Chem was able to convince Tesla to opt for its NCM 811 batteries under the premise that the cells will likely maximize the range of the Model 3. This is key to Tesla’s Model 3 production activities in Gigafactory 3, as the site is intended to produce only the affordable versions of the electric sedan. If Tesla can reassure China’s EV market that its Made-in-China Model 3 has industry-leading range, the vehicle will likely receive a good amount of demand from the country’s mainstream car-buying public.
With Tesla as a customer for its Nanjing based plant, LG Chem has reportedly begun preparing its facilities to meet the electric car maker’s demand. LG Chem’s Nanjing plant is already operating at high levels, and earlier this year, the South Korean conglomerate announced that it will be investing 1.2 trillion won ($1 billion) to expand the facility’s production capabilities even more. But this is not all, as more expansion is expected as per Tesla’s request.
Interestingly, the industry sources quoted by the South Korean tech publication mentioned that LG Chem is also looking to mass-produce NCMA batteries for electric vehicles starting in 2022. These upcoming cells will reportedly feature an even higher nickel content.
Reports of LG Chem’s partnership with Tesla initially emerged last August when Bloomberg revealed that the battery maker and the electric car company were in discussions for a potential working partnership. Provided that the recent reports from South Korea are accurate, the two companies’ collaboration appears to have been secured, and both companies appear to be working together to start Model 3 production in the Gigafactory 3 site.
LG Chem’s Nanjing battery plant is strategically located. The facility is situated about 200 miles west of Shanghai, which would make transporting the cells to the Gigafactory 3 complex at the Lingang Industrial Zone a rather simple task. For one, the distance between the two China-based facilities is far shorter than the distance between Tesla’s Gigafactory 1 in Nevada, which produces 2170 cells for the Model 3, and the company’s Fremont factory, which assembles the vehicle.
Reports from China have suggested that Tesla’s Gigafactory 3 will not be exclusively supplied by LG Chem. Apart from the South Korean battery maker, Tesla is reportedly tapping into the services of Contemporary Amperex Technology Co. Ltd (CATL) for a potential supply deal. So far, neither Tesla nor CATL have confirmed that a battery partnership has been established for Gigafactory 3’s operations.
Tesla CEO Elon Musk has tempered expectations for the company’s humanoid robot Optimus, emphasizing that initial production will ramp up slowly despite recent progress on the manufacturing line. In a July 1 reply on X, Musk responded to optimistic community speculation by stating, “No, Optimus production will be extremely slow at first, as everything is new. This is not like making a car.”

The comment came in response to a post theorizing that Tesla had accelerated Optimus V3 development and might soon unveil an impressive demonstration with multiple units already in meaningful production. Musk’s clarification highlights the fundamental differences between scaling a novel humanoid robot and Tesla’s established automotive operations, which benefit from over a century of refined supply chains, tooling, and processes.
Recent updates show tangible advancement. Musk shared a photo of himself walking the Optimus production line at Fremont, where Tesla is converting former Model S/X manufacturing space. According to Q1 2026 earnings commentary, limited production is slated to begin in late July or August 2026 on this converted line.
Tesla Optimus project fires up as Musk sees production line progress
Musk previously noted that Optimus features roughly 10,000 unique parts, making early output rates “literally impossible to predict” and describing them as “quite slow.” A larger dedicated factory at Giga Texas is under construction, targeting higher-volume production around summer 2027 with long-term annual capacity potentially reaching millions of units.
Some experts point out that pioneering humanoid robotics demands inventing new automation techniques, actuator supply chains, and quality-control standards in real time. Unlike vehicles, where components and assembly methods are mature, every element of Optimus—from dexterous hands to AI-integrated movement—requires fresh engineering solutions. Early units are expected to handle simple factory tasks before expanding to more complex roles.
This cautious approach aligns with Tesla’s history of under-promising and over-delivering on complex technologies. While enthusiasts hoped for rapid deployment, Musk’s message underscores a deliberate strategy: prioritize reliability and iterative improvement over rushed volume.
Analysts suggest the S-curve ramp typical of new manufacturing will eventually accelerate once foundational issues are resolved, positioning Optimus as a potential trillion-dollar product line.
Musk has long envisioned Optimus transforming labor markets, assisting in homes, factories, and hazardous environments. By setting realistic timelines, Tesla aims to build sustainable momentum rather than risk disappointment. As the Fremont line comes online this summer, investors and fans will watch closely for the first production metrics and capability demonstrations.
Tesla has officially launched the Model Y L in the United States and Puerto Rico for $61,990. It is the longer-wheelbase version of the Model Y, and has been available in China since last year.
Tesla brings the Model Y L to the U.S. just months after it phased out the only pure SUV in its lineup, the Model X. It is slightly longer than the Model Y configurations that are already available in the U.S., and features a three-row, six-seat setup with Captain’s Chairs being among the many features that make this a truly fantastic offering.
The Model Y L is priced competitively at $61,990, and features 325 miles of range and a 0-60 MPH in just 4.4 seconds.
Tesla also added a handful of new features that are not available in even the Premium Model Y. Here’s a full list of its features:
- Heated/Ventilated Front Seats with Powered Thigh Cushion
- Heated/Ventilated Captain’s Seats in Second Row with Powered Armrests & One-Touch Fold
- Heated Third-Row Seats with Power Recline, One-Touch Fold & Child Seat Anchors
- Improved Airflow, Increased Efficiency, More Range
- 89 cubic feet of trunk space
- Upgraded Acoustic Glass and Suspension to Minimize Road Noise
- Adaptive Damping for a Smooth, Stable Ride
- Staggered Tires for Enhanced Grip
- Larger Tailgate for Better Rear Visibility and Bigger Windows Overall
- 16″ First Row and 8″ Second Row Touchscreens
- 19-Speaker Immersive Tesla Audio
- 50W Wireless Charging Pads with Active Cooling and Charging Ports for All Other Seats

Tesla is also delivering these first units as a “Launch Series,” which comes with additional features, such as:
- Door Trim Puddle Lights
- Suede Dashboard Wing
- Exterior and Interior Badging
- Floor Mats
- Sill Plates
The launch of the Model Y L in the U.S. marks a huge offering from Tesla to U.S. consumers. People have been calling for Tesla to bring a larger car to the U.S., and it needed it more than ever now that the Model X is gone.

It is a huge accomplishment for Tesla to get the Model Y L to the U.S., and after reporting strong deliveries today, it will be interesting to see how this car impacts future quarterly delivery reports.
Deliveries for the Model Y L “Launch Series” are slated for September or October of this year.
Tesla just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.
The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.
The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.
With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.
However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.
Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.
Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.
Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.
