Tesla battery supplier LG Chem to double production capacity: report
Tesla battery supplier LG Chem will double its cell production capacity over the next year to keep up with the growing demand for Tesla’s electric vehicles in China, a new report says.
An exclusive report from Reuters states that sources familiar with the matter have talked about strategies moving forward to keep up with increasingly popular all-electric vehicles from Tesla. LG Chem, who supplies cells to Tesla in Shanghai for the production of the Model 3 sedan, stated that it would also ship its increased output from China and Korea to Tesla production facilities in the United States and Germany once they are completed. Tesla currently has a new production facility under construction in Austin, Texas, and in Brandenburg, Germany. Reuters indicated that two people who are familiar with the matter have seen LG Chem signal an increased role in the supply chain of Tesla as it continues to grow its lead in the EV production sector.
Tesla is LG Chem’s primary customer, and the plan to double its cell production capacity comes as Tesla begins to expand its global production processes aggressively. Tesla has been manufacturing vehicles in Shanghai for around a year and announced its intentions to build a European production facility around 13 months ago. Rumors also speculate that another factory could be on the way within the next few years, and India could be the location, but nothing has been confirmed.

LG Chem has already added additional production lines to increase the possible production capacity in South Korea this year. The main purpose of the expansion was to meet demand from Tesla’s U.S. plants, the two sources told Reuters. “Tesla simply doesn’t have enough battery cells, so LG Chem is going to more than double China outputs,” the person said.
Tesla sources batteries from Panasonic, LG Chem, and CATL, and CEO Elon Musk stated at the company’s Battery Day event in September that it plans to begin making its own 4680 cells that will be less expensive and more efficient. However, the company will continue to source batteries from suppliers for the time being, but could eventually become a battery supplier on its own as it has plans to open several battery cell production facilities across the globe.

To keep up with global demand, Tesla will have to source batteries from third-party sources for the time being, and an LG Chem spokesperson said that there is an increased demand for cells. However, he could not elaborate on who was the cause of the expansion in cell production capacity.
“We’re continuing to expand capacity for cylindrical battery cells in response to growing demand from automakers, but we can’t comment on specific customers,” an LG Chem spokesman told Reuters.
LG Chem plans to invest $500 million over the next year to raise the annual production of 2170 cells by 8 GWh. The 2170 cells are used in the Model 3 and Model Y, Tesla’s two mass-market vehicles. Currently, eight production lines are operational at the Nanjing, China plant that LG Chem manufactures its batteries, but it plans to expand its available lines to seventeen.
Tesla currently only manufactures the Model 3 at its Chinese production facility, but it plans to begin building the Model Y within the next few months. Because of the overwhelming demand for both the Model 3 and Model Y, the move to expand 2170 cell capacity is a no-brainer, especially considering the Government-offered subsidies that China provides for clean energy vehicles.
The person who spoke with Reuters also indicated that LG Chem’s Chinese factory would initially supply battery cells for Tesla’s Giga Berlin production facility in Germany when it begins production in Summer 2021.
Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it
— Elon Musk (@elonmusk) October 3, 2026
The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.
Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.
An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.
Tesla wins FCC approval for wireless Cybercab charging system
The Tesla employee would walk around and plug each car in, adjusting the parking if needed:
So look at what I found. This is how Tesla charges unsupervised robotaxis at a public supercharger. Here is a driverless Cybercab showing up with no one in it. There are 9 other Model Ys that showed up too. A Tesla employee is walking around and plugging each of them in. She also moves the cars if they are not positioned well enough to charge. I love this process. One person charges multiple robotaxis at once

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.
On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.
However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.
@Teslarati Sheer magnitude of the entire production system is hard to appreciate. Almost every element of production is >75% automated. Only wire harnesses & general assembly, which are <10% of production costs, are primarily manual.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.
Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.
CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.
The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.
In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.
The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.
Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”
Robotaxi operating hours moved from 10pm to 11pm.

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.
Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.
The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.
Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.
The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
