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.

CATL’s new LFP cell has 620+ miles of range and ultra-fast charging
Tesla has rolled out a new Supercharging safety feature in the United States, one that will answer concerns that some owners may have if they need to leave in a pinch.
It is also a suitable alternative for non-Tesla chargers, like third-party options that feature J1772 or CCS to NACS adapters.
The feature has been available in Europe for some time, but it is now rolling out to Model 3 and Model Y owners in the U.S.
With Software Update 2026.2.3, Tesla is launching the Unlatching Charge Cable function, which will now utilize the left rear door handle to release the charging cable from the port. The release notes state:
“Charging can now be stopped and the charge cable released by pulling and holding the rear left door handle for three seconds, provided the vehicle is unlocked, and a recognized key is nearby. This is especially useful when the charge cable doesn’t have an unlatch button. You can still release the cable using the vehicle touchscreen or the Tesla app.”
The feature was first spotted by Not a Tesla App.
This is an especially nice feature for those who commonly charge at third-party locations that utilize plugs that are not NACS, which is the Tesla standard.
For example, after plugging into a J1772 charger, you will still be required to unlock the port through the touchscreen, which is a minor inconvenience, but an inconvenience nonetheless.
Additionally, it could be viewed as a safety feature, especially if you’re in need of unlocking the charger from your car in a pinch. Simply holding open the handle on the rear driver’s door will now unhatch the port from the car, allowing you to pull it out and place it back in its housing.
This feature is currently only available on the Model 3 and Model Y, so Model S, Model X, and Cybertruck owners will have to wait for a different solution to this particular feature.

LG Energy Solution pursuing battery deal for Tesla Optimus, other humanoid robots: report
Optimus is expected to be one of Tesla’s most ambitious projects, with Elon Musk estimating that the humanoid robot could be the company’s most important product.
A recent report has suggested that LG Energy Solution is in discussions to supply batteries for Tesla’s Optimus humanoid robot.
Optimus is expected to be one of Tesla’s most ambitious projects, with Elon Musk estimating that the humanoid robot could be the company’s most important product.
Humanoid robot battery deals
LG Energy Solution shares jumped more than 11% on the 28th after a report from the Korea Economic Daily claimed that the company is pursuing battery supply and joint development agreements with several humanoid robot makers. These reportedly include Tesla, which is developing Optimus, as well as multiple Chinese robotics companies.
China is already home to several leading battery manufacturers, such as CATL and BYD, making the robot makers’ reported interest in LG Energy Solution quite interesting. Market participants interpreted the reported outreach as a signal that performance requirements for humanoid robots may favor battery chemistries developed by companies like LG.
LF Energy Solution vs rivals
According to the report, energy density is believed to be the primary reason humanoid robot developers are evaluating LG Energy Solution’s batteries. Unlike electric vehicles, humanoid robots have significantly less space available for battery packs while requiring substantial power to operate dozens of joint motors and onboard artificial intelligence processors.
LG Energy Solution’s ternary lithium batteries offer higher energy density compared with rivals’ lithium iron phosphate (LFP) batteries, which are widely used by Chinese EV manufacturers. That advantage could prove critical for humanoid robots, where runtime, weight, and compact packaging are key design constraints.

Tesla receives approval for FSD Supervised tests in Sweden
Tesla confirmed that it has been granted permission to test FSD Supervised vehicles across Sweden in a press release.
Tesla has received regulatory approval to begin tests of its Full Self-Driving Supervised system on public roads in Sweden, a notable step in the company’s efforts to secure FSD approval for the wider European market.
FSD Supervised testing in Sweden
Tesla confirmed that it has been granted permission to test FSD Supervised vehicles across Sweden following cooperation with national authorities and local municipalities. The approval covers the Swedish Transport Administration’s entire road network, as well as urban and highways in the Municipality of Nacka.
Tesla shared some insights into its recent FSD approvals in a press release. “The approval shows that cooperation between authorities, municipalities and businesses enables technological leaps and Nacka Municipality is the first to become part of the transport system of the future. The fact that the driving of the future is also being tested on Swedish roads is an important step in the development towards autonomy in real everyday traffic,” the company noted.
With approval secured for FSD tests, Tesla can now evaluate the system’s performance in diverse environments, including dense urban areas and high-speed roadways across Sweden, as noted in a report from Allt Om Elbil. Tesla highlighted that the continued development of advanced driver assistance systems is expected to pave the way for improved traffic safety, increased accessibility, and lower emissions, particularly in populated city centers.
Tesla FSD Supervised Europe rollout
FSD Supervised is already available to drivers in several global markets, including Australia, Canada, China, Mexico, New Zealand, and the United States. The system is capable of handling city and highway driving tasks such as steering, acceleration, braking, and lane changes, though it still requires drivers to supervise the vehicle’s operations.
Tesla has stated that FSD Supervised has accumulated extensive driving data from its existing markets. In Europe, however, deployment remains subject to regulatory approval, with Tesla currently awaiting clearance from relevant authorities.
The company reiterated that it expects to start rolling out FSD Supervised to European customers in early 2026, pending approvals. It would then be unsurprising if the company secures approvals for FSD tests in other European territories in the coming months.
