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 roasts India’s billionaire Mukesh Ambani as Starlink fight heats up
Elon Musk sarcastically calls Mukesh Ambani ‘Prime Minister’ as the Starlink India standoff escalates again.
Elon Musk escalated his public fight over Starlink’s launch in India on Friday, addressing Reliance chairman Mukesh Ambani as “Prime Minister Ambani” in a sarcastic post on X. “Please accept my humble apologies for not realizing that you are the real boss of India,” Musk wrote, before accusing Ambani of “monopolistic exploitation” and asking whether he would “consider allowing Starlink to compete.” In follow up posts, he said Starlink has proven essential during natural disasters and would help parts of India with no internet access.
The post came two days into a fight that Musk sparked up on Wednesday, when he said Starlink was “being blocked by certain oligarchs in order to maintain their monopolistic chokehold on the Indian people.” He called it “a crime against the people of India” and left the names out, adding only, “You can guess who they are.” Jio and Airtel together hold more than 80% of India’s telecom market. On Thursday, Musk asked whether Ambani is “the real boss of India” and said Starlink has spent five years complying with “every single law and requirement” of the Indian government.
Dear Prime Minister Ambani,
Please accept my humble apologies for not realizing that you are the real boss of India.
Naturally, you would prefer to maintain your monopolistic exploitation of the great people of India, but would you nonetheless consider allowing Starlink to compete?
There are many areas of India, as there are in all countries, with no Internet access, which denies children the opportunity for education and for small businesses the opportunity to sell their goods to a global market. Starlink would change their lives for the better.
Thank you 🙏

India’s government has pushed back each time. The Ministry of Communications called the suggestion that its framework is unfair or discriminatory “baseless and misconceived.” Communications Minister Jyotiraditya Scindia said Friday that three companies hold satcom licenses: Starlink, Jio Satellite Communications, and Bharti backed Eutelsat OneWeb. Amazon’s Kuiper, now Amazon Leo, is still going through the process. None can launch until regulators finalize satellite spectrum pricing and the Home Ministry signs off on each company’s security compliance. Scindia said the telecom regulator and the Department of Telecommunications are close to a decision on pricing, The Hindu reported. Bharti chairman Sunil Mittal also said OneWeb is still waiting on approvals.
Starlink received its operator license in 2025 after a three year wait, and the space regulator IN-SPACe granted what industry executives called the last approval needed in July. The holdup since then centers on security, particularly concern that foreign operators could bypass Indian gateways.
Musk and Ambani have been on opposite sides of this before. In late 2024, Ambani argued for auctioning satellite spectrum, which Musk criticized as out of step with the rest of the world, and India chose administrative allocation instead. By March 2025, the two sides had signed a deal to sell Starlink devices in Reliance stores, and Starlink secured its telecom license that June. That partner is now also a competitor. Jio is reportedly weighing a constellation of 1,600 to 1,650 satellites costing an estimated $10 billion to $15 billion, while Akash Ambani has told shareholders Jio plans to lease capacity from global providers to move quickly.

Elon Musk’s surprise addition to the X Takeover lineup has fans talking
Elon Musk will join Saturday’s X Takeover at Giga Texas for a live virtual interview.
Elon Musk will join X Takeover at Giga Texas on Saturday for a live virtual interview, according to Sawyer Merritt, who shared the news late Thursday. Musk will not be on stage in Austin. The conversation is set to stream for free on the @teslaownersSV account on X.
Organizers had kept expectations in check. In a September update, Tesla Owners Silicon Valley said Musk had appeared at the event twice before but was not promising a third appearance, even as fans hoped he would walk the Giga Texas grounds in person. A virtual spot matches 2024, when Musk gave a surprise interview of about an hour to the crowd in San Luis Obispo, as Teslarati reported at the time.
Wasn’t expecting this 🫡
— Tesla Owners Silicon Valley (@teslaownersSV) October 9, 2026
This year’s edition is a first in several ways. It is the first X Takeover held outside California and the first at a Tesla facility, with tickets selling out in eight days. Tesla provides the venue, but the event is produced independently by Tesla Owners Silicon Valley. The main event runs from 10 a.m. to 6 p.m. CT, followed by a drone and light show at 9 p.m. Maye Musk is the keynote speaker, Franz von Holzhausen is set for a virtual keynote, and Nicki Minaj is the special guest. Joe Tegtmeyer, whose drone footage Teslarati used to track the Optimus factory steel frame at Giga Texas, is also on the speaker list.
Musk’s interview topics have not been revealed, but the backdrop is busy. Tesla doubled its Cybercab fleet in Austin in late September, and last week Musk explained why Robotaxi hours only moved from 10 p.m. to 11 p.m.. Merritt also reported Thursday that Texas DMV records now show 319 registered Cybercabs, up from 169. NHTSA’s deadline for Tesla’s sworn answers on Cybercab certification is October 30, and Tesla reports third quarter earnings on October 21.
Fans who cannot make it to Austin can watch the livestream on X. Musk tends to say more in unscripted settings than he does in prepared remarks, which is the reason this one is worth having open on Saturday.

It’s official: SpaceX takes aim at Verizon, AT&T, and T-Mobile
SpaceX is buying 800 MHz spectrum from Grain to turn Starlink Mobile into a carrier.
SpaceX has agreed to buy a nationwide block of low band wireless spectrum, a deal the company says will let Starlink Mobile operate as a full US carrier rather than a satellite add-on for someone else’s network.
The company announced the agreement on X on Thursday afternoon, saying it will “pave the way for @Starlink to become a major mobile carrier in the US.” The seller is Grain Management, a private investment firm that confirmed in a statement that SpaceX will acquire 100% of its nationwide 800 MHz portfolio. That covers up to 14 MHz of paired spectrum in the 817 to 824 MHz and 862 to 869 MHz bands. Neither side disclosed a price, and the deal still needs FCC approval.
We announced an agreement to acquire a nationwide low-band spectrum license portfolio that will pave the way for @Starlink to become a major mobile carrier in the US.
With this new spectrum and our Gen2 constellation, Starlink Mobile can ensure Americans have access to high-speed mobile broadband no matter where they are → https://t.co/1Uaf48v5pm

Grain only recently picked up the licenses itself. It bought the portfolio from T-Mobile in a transaction that closed in August, paying cash plus its own 600 MHz spectrum. Rival AST SpaceMobile had been testing satellites on the same bands before SpaceX stepped in.
SpaceX said its 2 GHz spectrum will handle high bandwidth capacity, while the new 800 MHz layer “ensures Starlink Mobile’s signal penetrates through obstacles, such as walls, and can provide service to customers’ devices even when they are in buildings.” The company added that most existing phones already support the band, so customers would not need new hardware to use it.
That 2 GHz spectrum came from SpaceX’s EchoStar acquisition last year, which gave the company exclusive S band rights in the US and global Mobile Satellite Service licenses. The Grain spectrum is different in an important way: it is tailored for service from ground towers, not satellites. SpaceX said that combination would make Starlink Mobile “the first network operator to deploy both satellite and terrestrial spectrum.”
The announcement also follows a key regulatory win. Earlier this week, the FCC approved SpaceX’s plan to deploy 15,000 second generation Starlink Mobile satellites, which the company has said will carry up to 100 times the data density of the current system, as Teslarati previously reported.
Shares of AT&T, Verizon and T-Mobile fell in extended trading after the announcement. T-Mobile is currently SpaceX’s launch partner for Starlink Mobile in the US, which makes its position the most complicated of the three.
SpaceX has not been subtle about its plans. During the company’s August earnings call, President and COO Gwynne Shotwell said she expected Starlink Mobile to win over customers from the major carriers. “I anticipate us to be able to acquire quite a few of their customers because I think our service will be better,” she said, pointing to dead zone coverage and resilience during disasters. Shotwell also described plans for low cost cellular base stations that could pair with existing Starlink dishes.
SpaceX has targeted 2027 for deployment of its next generation Starlink Mobile satellites, with upgraded service expected by the end of that year. The FCC review of the Grain deal now determines when the terrestrial half of that network can come online.
