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.

New York City Comptroller Brad Lander is urging the NYC Law Department to sue Tesla for securities violations related to CEO Elon Musk’s involvement in the Department of Government Efficiency (DOGE).
Lander said the basis for the potential litigation lies on “material misstatements from Tesla claiming that CEO Elon Musk spends significant time on the company and is highly active in its management, despite his helming the Trump Administration’s DOGE initiative.”
🚨 NEWS: New York City Comptroller Brad Lander wants to sue Tesla by claiming CEO Elon Musk’s role as the head of DOGE is hurting the stock.

It is a common complaint amongst some Tesla shareholders who are less than enthusiastic about Musk’s involvement in DOGE. Some feel as if Musk is not concerned about Tesla, especially as the stock has dropped over 28 percent this year. However, Musk has continued to double down on his position within the U.S. government.
Nevertheless, Musk’s position in Tesla is still very apparent. He headed an All-Hands meeting just two weeks ago that showed his commitment to the company as he outlined future plans and even joked to employees that they should hold onto their stock.
However, Lander believes Musk’s involvement has hurt New York City pension systems, which have lost over $300 million so far this year. He said:
“In less than three months, Tesla stock has lost nearly 40% of its value, with losses over $300 million for the New York City pension systems. We have long expressed concerns that the Tesla board has failed to provide independent oversight, or to require that Musk – or someone else – serve as a full-time CEO.”
Lander went on to say that “material misstatements from Tesla misled investors about his role at the company,” stating this was his reasoning for calling on the Law Department to file securities litigation against the company.
He believes taking it to court will force changes and will return Tesla shares back to a level that will benefit pension systems in New York City:
“Shareholder litigation could force the changes in governance and leadership that Tesla needs, and help recover some of our pension systems’ losses. Otherwise, we may need to consider divestment.”
The pension systems would be able to pursue financial damages to cover losses and seek governance changes, it says.
Tesla is testing a Model 3 with some mysterious cameras, potentially hinting toward the imminent release of the Cybercab and robotaxi platform in the United States.
After Tesla unveiled the Cybercab in Los Angeles in early October, the company suggested that it would be on its way to launching driverless rides in the U.S. in the near future.
Now, Tesla is inching toward a driverless ride-hailing service in Austin, Texas, among some other potential locations, but it is still working toward a platform that is robust enough to handle it.
Although the company’s Full Self-Driving suite is one of the more advanced on the market, Tesla is still working to accomplish what it feels is a mode of transportation that is safer than a human driver. The robotaxi and Cybercab rollouts will likely accomplish that, but there is still work to be done beforehand.
Now, Tesla is testing a Model 3 in the U.S. that was spotted in several different locations in the Northeastern part of the country, as cameras are seen on this vehicle in locations that are not necessarily typical for what it offers currently:

Interestingly, we saw similar camera locations on the Cybercab at the event in October. Tesla is not testing the Cybercab but instead implementing these cameras on a comparable position on its other vehicles.
These are the cameras we spotted on the Cybercab at the event in October:
In the past, Tesla has used a variety of strategies to measure self-driving accuracy, including LiDAR, which has been seen on some testing mules that we have spotted out in public.
Tesla CEO Elon Musk has said that the company does not need LiDAR on testing mules for ground truth, but we still spot them from time to time on public roads.
It’s an appropriate way just to cross Ts and dot Is:

The company is still moving toward that initial rollout of driverless ride-hailing in Austin in June, and some company executives have stated that the Cybercab will be the vehicle it uses for these initial rides.
Tesla is bolstering its release of features to Android users as it is rolling out some new things with its latest software update.
Update v4.43.5 will see Tesla add a Dashcam Viewer for Android phones, a new feature that will make it simpler to access and manage both Dashcam and Sentry Mode videos. This has been available to iPhone users for some time, but Android owners have not had access to this quite yet.
Tesla describes the release of the feature in release notes (via Not a Tesla App):
“The Dashcam Viewer is now available in the Tesla app for Android users.
The Dashcam Viewer makes it easy to access and manage your car’s Dashcam and Sentry Mode videos. Accessing videos on your phone is faster and more convenient, but it does come with a few requirements.
The Dashcam Viewer in the Tesla app allows you to view, delete, or save video clips right from your device. This should result in higher quality content being shared online and fewer videos of owners recording their Tesla’s screens with their phones.”
The feature creates a more convenient option to view things that your Tesla has captured on its dashcam or on its external cameras through Sentry Mode, its security camera system that records things that happen around the vehicle.
Sentry Mode has been a great addition for Tesla owners lately, as more and more instances of vandalism have been occurring in the past few months.
It seems Tesla might have made it a point to roll this feature out, especially as it would allow those who are getting Sentry Mode alerts to capture footage of keying or tire slashing, two common techniques used by those who dislike Tesla and/or Elon Musk.
Tesla quietly added this extra Sentry Mode feature to deter vandals
The last time Tesla rolled out some features to Android owners was in January when it beefed up offerings for those who do not use iOS. The January update saw Phone Key Improvements and Hands-Free Trunk Opening make their way to Android users.
