A chairman from China-based battery giant Contemporary Amperex Technology Co. Limited (CATL) recently cast doubt on Tesla’s 4680 battery cell, saying that he didn’t think it would be successful in the long run.
In a conversation earlier this year, CATL Chairman Robin Zeng told Elon Musk that the cylindrical 4680 battery “is going to fail and never be successful,” according to a report from Reuters this week. Zeng made the statements to Musk in a meeting with the Tesla CEO on his Beijing visit in April, and the chairman also said that the Tesla CEO was better equipped to handle other technologies than battery cells.
“We had a very big debate, and I showed him,” Zeng said. “He was silent. He doesn’t know how to make a battery. It’s about electrochemistry. He’s good for the chips, the software, the hardware, the mechanical things.”

Tesla’s 4680 battery cell and CATL licensing
In September, Tesla announced that it had produced its 100 millionth 4680 battery cell at Gigafactory Texas, after reaching 50 million units in June. The company is also in the process of expanding its Gigafactory Nevada to add a dedicated 4680 cell production facility, expected to ramp up to 500 GWh in the long term.
The report also highlights a licensing deal Tesla has with CATL for technology related to producing batteries in Nevada, expected to officially launch in 2025, according to a person with knowledge of the matter who spoke to Reuters under the condition of anonymity.
Zeng on FSD Supervised and Musk’s promise timelines
In addition to discussing battery technology, the chairman said that he and Musk talked about the company’s focus on autonomy, adding that he agrees with Tesla’s overall approach to the topic. Unlike other companies that are developing self-driving systems, Tesla’s Supervised Full Self-Driving (FSD) only utilizes cameras as sensors, rather than using multiple layers of different redundant technologies.
“He’s all in,” Zeng told Reuters regarding Musk and Tesla’s FSD strategy in a statement earlier this month. “I think it’s a good direction.”
Despite his support for the company’s approach to FSD Supervised, Zeng also noted that he thinks Musk tends to set unrealistic timelines for new vehicle technologies, and he even asked the Tesla CEO during the April conversation, saying two-year timelines may as well be “infinity.”
“His problem is overpromising. I talked to him,” the chairman added. “Maybe something needs five years. But he says two years. I definitely asked him why. He told me he wanted to push people.”
Musk has addressed criticisms of his timelines before, pointing to his optimism as a necessary part of his accomplishments.
While certainly not perfect, my batting average for most predictions is quite good.
My schedule optimism, without which I probably wouldn’t even have tried to do many endeavors, gets the best of me sometimes, but I always deliver in the end.— Elon Musk (@elonmusk) December 30, 2023
“Now, admittedly I’m a little optimistic sometimes,” Musk said during this year’s Annual Shareholders Meeting. “You know, I don’t have a complete lack of self awareness. But if I wasn’t optimistic, this wouldn’t exist this factory wouldn’t exist.”
The CEO later went on to add that he believes he’s been “pathologically optimistic from birth.”
CATL hopes for U.S. factory under Trump
CATL also told Reuters that it would build a U.S. production facility if President-elect Donald Trump would allow it.
“Originally, when we wanted to invest in the U.S., the U.S. government said no,” Zeng said. “For me, I’m really open-minded.”
“I do hope that in the future they are open to investments,” the chairman added.
In August, Trump expressed that he would be open to Chinese companies building factories in the U.S., despite the country’s recent passage of a 100-percent tariff on electric vehicle (EV) imports.
“We’re going to give incentives, and if China and other countries want to come here and sell the cars, they’re going to build plants here, and they’re going to hire our workers,” Trump said in a statement to the publication in August.

Elon Musk’s Boring Company signs deal to begin Dubai Loop project
The project marks the Boring Company’s first tunneling project outside the United States.
Elon Musk’s Boring Company has signed a definitive agreement with Dubai’s Roads and Transport Authority to begin implementing the Dubai Loop.
The project marks the Boring Company’s first tunneling project outside the United States.
The Boring Company signs Dubai Loop agreement
The Boring Company signed a partnership agreement with Dubai Roads and Transport Authority on the sidelines of the World Governments Summit 2026 to start the implementation of the Dubai Loop, as per the tunneling startup in a blog post.
The agreement was signed on behalf of Dubai RTA by Mattar Al Tayer, director general and chairman of the Board of Executive Directors, and on behalf of The Boring Company by James Fitzgerald, the startup’s global vice president of business development. Senior officials from both organizations were present at the signing ceremony.
The Dubai Loop project is intended to improve passenger mobility in high-density urban areas through underground vehicle tunnels designed for faster construction and lower surface disruption than conventional transport systems.
Pilot route and project scope outlined
The first phase of the Dubai Loop will consist of a 4-mile (6.4 km) pilot route with four stations linking the Dubai International Financial Centre and Dubai Mall. The pilot phase is expected to pave the way for a full network extending up to 14 miles (22.5 km) with 19 stations connecting the Dubai World Trade Centre, the financial district, and Business Bay.
The tunnels will have a diameter of 12 feet (3.6 meters) and will be dedicated to vehicle transport. Construction will rely on tunneling methods designed to reduce costs and minimize disruption to existing infrastructure.
The pilot phase is estimated to cost about $154 million, with delivery expected roughly one year after design work and preparatory activities are completed. The full Dubai Loop network is projected to cost approximately $545 million and would take around three years to implement.
Capacity targets and next steps
Mattar Al Tayer shared his excitement about the project, stating that the Loop system will be a qualitative addition to the city’s transportation system. “The project represents a qualitative addition to Dubai’s transport ecosystem, as it enhances integration between different mobility modes and provides flexible and efficient first- and last-mile solutions.
“Studies have demonstrated the project’s efficiency in terms of capacity and operating costs, with the pilot route expected to serve around 13,000 passengers per day, while the full route is projected to have a total capacity of approximately 30,000 passengers per day,” he said.
Steve Davis, president of The Boring Company, highlighted that the partnership aims to deliver safe and efficient tunneling solutions aligned with Dubai’s long-term mobility strategy.
“We are proud to partner with the Roads and Transport Authority, one of the world’s leading entities in adopting innovative solutions in the transport sector. Through this partnership, we look forward to delivering advanced, safe, and highly efficient tunnelling solutions that support Dubai’s vision for sustainable and future mobility,” Davis stated.
Tesla executive Sendil Palani confirmed in a post on social media platform X that Full Self-Driving, despite being the most robust driver assistance program in the United States, still isn’t garnering any interest from lagging competitors.
Tesla has said on several occasions in the past that it has had discussions with a competing carmaker to license its Full Self-Driving suite. While it never confirmed which company it was, many pointed toward Ford as the one Tesla was holding dialogue with.
At the time, Ford CEO Jim Farley and Tesla CEO Elon Musk had a very cordial relationship.
Despite Tesla’s confirmation, which occurred during both the Q2 2023 and Q1 2024 Earnings Calls, no deal was ever reached. Whichever “major OEM” Tesla had talked to did not see the benefit. Even now, Tesla has not found that dance partner, despite leading every company in the U.S. in self-driving efforts by a considerable margin.

Palani seemed to confirm that Tesla still has not found any company that is remotely interested in licensing FSD, as he said on X that “despite our best efforts to share the technology,” the company has found that it “has not been proven to be easy.”

The question came just after one Tesla fan on X asked whether Tesla would continue manufacturing vehicles.
Because Tesla continues to expand its lineup of Model Y, it has plans to build the Cybercab, and there is still an immediate need for passenger vehicles, there is no question that the company plans to continue scaling its production.
However, Palani’s response is interesting, especially considering that it was in response to the question of whether Tesla would keep building cars.
Perhaps if Tesla could license Full Self-Driving to enough companies for the right price, it could simply sell the suite to car companies that are building vehicles, eliminating the need for Tesla to build its own.
While it seems like a reach because of Tesla’s considerable fan base, which is one of the most loyal in the automotive industry, the company could eventually bail on manufacturing and gain an incredible valuation by simply unlocking self-driving for other manufacturers.
The big question regarding why Tesla can’t find another company to license FSD is simply, “Why?”
Do they think they can solve it themselves? Do they not find FSD as valuable or effective? Many of these same companies didn’t bat an eye when Tesla started developing EVs, only to find themselves years behind. This could be a continuing trend.
Tesla executive Lars Moravy appeared today in front of the U.S. Senate Commerce Committee to highlight the importance of modernizing autonomy standards by establishing a federal framework that would reward innovation and keep the country on pace with foreign rivals.
Moravy, who is Tesla’s Vice President of Vehicle Engineering, strongly advocated for Congress to enact a national framework for autonomous vehicle development and deployment, replacing the current patchwork of state-by-state rules.
These rules have slowed progress and kept companies fighting tooth-and-nail with local legislators to operate self-driving projects in controlled areas.

Moravy said the new federal framework was essential for the U.S. to “maintain its position in global technological development and grow its advanced manufacturing capabilities.
He also said in a warning to the committee that outdated regulations and approval processes would “inhibit the industry’s ability to innovate,” which could potentially lead to falling behind China.
Being part of the company leading the charge in terms of autonomous vehicle development in the U.S., Moravy highlighted Tesla’s prowess through the development of the Full Self-Driving platform. Tesla vehicles with FSD engaged average 5.1 million miles before a major collision, which outpaces that of the human driver average of roughly 699,000 miles.
Moravy also highlighted the widely cited NHTSA statistic that states that roughly 94 percent of crashes stem from human error, positioning autonomous vehicles as a path to dramatically reduce fatalities and injuries.

Skeptics sometimes point to cybersecurity concerns within self-driving vehicles, which was something that was highlighted during the Senate Commerce Committee hearing, but Moravy said, “No one has ever been able to take over control of our vehicles.”
This level of security is thanks to a core-embedded central layer, which is inaccessible from external connections. Additionally, Tesla utilizes a dual cryptographic signature from two separate individuals, keeping security high.
Moravy also dove into Tesla’s commitment to inclusive mobility by stating, “We are committed with our future products and Robotaxis to provide accessible transportation to everyone.” This has been a major point of optimism for AVs because it could help the disabled, physically incapable, the elderly, and the blind have consistent transportation.
Overall, Moravy’s testimony blended urgency about geopolitical competition, especially China, with concrete safety statistics and a vision of the advantages autonomy could bring for everyone, not only in the U.S., but around the world, as well.
