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.
Tesla China signs contract with LG Chem for Model Y production
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.
A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
