Tesla battery supplier LGES to invest $450M in 4680 cell assembly line
Tesla’s longtime battery supplier LG Energy Solutions (LGES) announced that it would invest 730 billion won ($567.76 million) to expand its battery production capacity in South Korea. The expansion includes a new assembly line that would produce 4680 cylindrical battery cells, stated a note to the press LGES provided Teslarati.
The investment is in line with our decision to better cope with the global EV manufacturers’ ever-increasing interests in adopting cylindrical batteries,” said Youngsoo Kwon, CEO of LG Energy Solution. “We will establish a diversified product portfolio that includes pouch-type, cylindrical, and other types of battery cells, to respond in a timely manner to our clients’ needs, thereby improving customer value.”
LGES plans to invest 580 billion won ($450 million) to add an assembly line that would produce 4680 cylindrical battery cells at its No.2 Ochang factory. The new assembly line with have a production capacity of 9GWh.
LGES will also invest 150 billion won ($116 million) in its No.1 Ochang factory to increase the assembly line producing 2170 battery cells by 4GWh. The battery supplier stated that the two new lines will be ready for mass production by the second half of 2023.
Earlier this year, LGES told Teslarati that it is working on diversifying its cylindrical battery lineup and confirmed that it is developing 4680 batteries. LGES supplies batteries to several prominent electric car manufacturers, including Tesla and Volkswagen.
Tesla’s other battery supplier, Panasonic, announced it had already shipped 4680 cell samples to the Texas-based EV automaker. According to the CEO of Panasonic’s energy business, Kazuo Tadanobu, the company’s pilot line in Japan started large-scale prototype production of the 4680 battery cell in May.
LGES also plans to expand its operations to the United States. In March, it announced plans to build a $1.4 billion battery production facility in Arizona as demand for electric vehicles in the United States continues to skyrocket. It specifically stated that the Arizona battery plant would cater to the demand from “prominent startups” and other North American companies. The $1.4 billion battery plant is expected to start operations by 2024.
“With the establishment of our new Arizona plant, LG Energy Solution aims to deliver unparalleled consumer value in the rapidly growing cylindrical battery market,” Youngsoo Kwon, CEO of LG Energy Solution, said. “LGES will provide the most dependable, competitive and advanced products to rise as the best business partner that our clients value and trust.”

Elon Musk’s Boring Company studying potential Giga Nevada tunnel: report
The early-stage feasibility work was funded by a state-affiliated economic group as officials searched for alternatives to worsening traffic and accidents along Interstate 80.
Elon Musk’s tunneling startup, The Boring Company, has been studying a potential tunnel system connecting Reno to Tesla Gigafactory Nevada, as per documents obtained by Fortune. The early-stage feasibility work was funded by a state-affiliated economic group as officials searched for alternatives to worsening traffic and accidents along Interstate 80.
Potential Giga Nevada tunnel
Documents reviewed by Fortune showed that The Boring Company received $50,000 in October to produce conceptual designs and a feasibility report for a tunnel beneath a nine-mile stretch of highway leading to Gigafactory Nevada. The payment came from the Economic Development Authority of Western Nevada (EDAWN), a nonprofit that works with the state to attract and expand businesses.
The proposed tunnel was one of several transportation alternatives being explored to address rising congestion and accidents along Interstate 80, which serves the Tahoe-Reno Industrial Center. The massive industrial park houses major employers, including Tesla and Panasonic, both of which had been in contact with the Nevada Governor’s Office regarding potential transportation solutions.
Emails obtained through public records requests showed that Tesla and Panasonic have also supported a separate commuter rail study that would use existing freight rail alongside the Interstate. It remains unclear if The Boring Company’s feasibility report had been completed, and key details for the potential project, including tunnel length, cost, and if autonomous Teslas would be used, were not disclosed.

Relieving I-80 congestion
Traffic and accidents along I-80 have increased sharply as data centers and new businesses moved into the 107,000-acre industrial center. State transportation data showed that the number of vehicles traveling certain stretches of the highway during peak hours doubled between January and July 2025 alone. Roughly 22,000 employees commute daily to the industrial park, with nearly 8,000 working for Tesla and more than 4,000 for Panasonic at the Giga Nevada complex.
Bill Thomas, who runs the Regional Transportation Commission of Washoe County, shared his thoughts about safety concerns in the area. “At this point in time, there’s about (one accident) every other day,” he said. He also noted that he is supportive of any projects that could alleviate traffic and accidents on the Interstate.
“We’re not paying for it. I’m not involved in it. But I understand there are conversations exploring whether that could be done. If there’s a private solution that helps the problem and improves safety, as far as I’m concerned, more power to them,” Thomas stated.

Tesla might have built redundancies for Cybercab charging
When Tesla unveiled the Cybercab in 2024, the company noted that the autonomous two-seater would utilize wireless charging.
A newly spotted panel on Tesla’s Cybercab prototype may point to a practical backup for the vehicle’s wireless charging system as it nears mass production.
Tesla watchers have speculated that the panel could house a physical NACS port, which would ensure that the autonomous two-seater could operate reliably even before the company’s wireless charging infrastructure is deployed.
Cybercab possible physical charge port
The discussion was sparked by a post on X by Tesla watcher Owen Sparks, who highlighted a rather interesting panel on the Cybercab’s rear. The panel, which seemed to be present in the prototype units that have been spotted across the United States recently, seemed large enough to house a physical charge port.
When Tesla unveiled the Cybercab in 2024, the company noted that the autonomous two-seater would utilize wireless charging. Since then, however, Tesla has remained largely quiet about the system’s rollout timeline. With the Cybercab expected to enter production in a few months, equipping the vehicle with a physical NACS port would allow it to charge at Superchargers nationwide without relying exclusively on still-undeployed wireless chargers.
Such an approach would not rule out wireless charging long-term. Instead, it would give Tesla flexibility, allowing the Cybercab to operate immediately at scale while wireless charging solutions are rolled out later. For a vehicle designed to operate continuously and autonomously, redundancy in charging options would be a practical move.
Growing Cybercab sightings
Recent sightings of the Cybercab prototype in Chicago point to the same design philosophy. Images shared on social media showed the vehicle coated in road grime, while its rear camera area appeared noticeably cleaner, with visible traces of water on the trunk.
The observation suggests that the Cybercab is equipped with a rear camera washer. As noted by Model Y owner and industry watcher Sawyer Merritt, this is a feature Tesla owners have requested for years, particularly in snowy or wet climates where dirt and slush can obscure cameras and degrade the performance of systems like FSD.
While only the rear camera washer was clearly visible, the sighting raises the possibility that Tesla may equip additional exterior cameras with similar cleaning systems. For a vehicle that operates without a human driver, after all, maintaining camera visibility in all conditions is essential. Ultimately, the charge-port speculation and camera-washer sightings suggest Tesla is approaching the Cybercab with practicality in mind.

Tesla Model Y dominated China’s NEV sales in December 2025
As per sales data from China, the all-electric crossover finished first among the country’s best-selling EVs and plug-in hybrids.
The Tesla Model Y ranked as China’s top-selling new energy vehicle in December, leading an intensely competitive market packed with strong domestic brands.
As per sales data from China, the all-electric crossover finished first among the country’s best-selling EVs and plug-in hybrids. The Model 3 also placed within the country’s top ten vehicles.
Model Y leads China’s NEV rankings
The graphic, shared on X and sourced from Chinese auto industry data aggregator Yiche, listed the top 20 best-selling new energy vehicles in China for December. Tesla’s Model Y claimed the No. 1 position with roughly 65,874 units sold, finishing well ahead of a field dominated by domestic manufacturers such as BYD, SAIC-GM-Wuling, and Xiaomi.
The chart also showed strong performances from other high-volume models, including BYD’s Qin Plus, which sold 46,837 units during the month. Tesla’s Model 3 ranked eighth overall, with just under 28,000 units sold, placing it ahead of numerous locally produced competitors despite its rather premium price.
Tesla China’s strong December
Tesla China had a stellar December 2025. During the month, Tesla sold 97,171 vehicles wholesale in China, as per data from the China Passenger Car Association (CPCA). The result marked Tesla China’s second-highest monthly total on record, trailing only November 2022’s peak of 100,291 units.
December’s wholesale figure represented a 3.63% increase from the same month a year earlier and a 12.08% jump from November. Industry watchers have suggested that part of the surge was driven by Tesla pulling deliveries forward to allow customers to benefit from more favorable purchase tax policies before year-end.
Despite this, December’s results suggest that Tesla’s Model Y and Model 3 remain highly competitive offerings in China, which is extremely impressive considering the competition from domestic players and their still premium price.
