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 lithium iron phosphate (LFP) batteries, which are widely used by Chinese manufacturers. That advantage could prove critical for humanoid robots, where runtime, weight, and compact packaging are key design constraints.

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. 

Amid Tesla Sweden’s ongoing conflict with trade union IF Metall, a group of pro-union supporters has begun directing their attention to actual Tesla owners.

As part of their efforts, the group has started distributing informational leaflets to Tesla vehicles across Stockholm, urging them to pressure the electric vehicle maker to sign a collective agreement.

Leaflets on parked Tesla vehicles

As noted in a Dagens Arbete (DA) report, participants of the protest place yellow information slips on parked Tesla vehicles across parts of Stockholm. The slips resemble parking notices that contain information related to the unions’ ongoing strike against Tesla Sweden.

Participants involved in the activity said the leaflets were intended to inform consumers rather than target individual owners. The action was carried out in public areas, with leaflets placed on windshields of parked vehicles. When vehicle owners are present, organizers said they provide verbal explanations of the labor dispute.

Tesla has not commented publicly about the matter as of writing.

Recurring demonstrations against Tesla

The leaflet distribution effort follows weekly demonstrations that have taken place outside Tesla’s workshop and office in Upplands Väsby, where protesters typically gather to express support for a collective agreement. Those demonstrations have included informational outreach to customers and workers and, at times, police presence, according to prior reporting.

In a comment, one of the protesters stated that even Tesla owners must be concerned about the unions’ conflict with the electric vehicle maker. “You may think it doesn’t concern you, as you only drive a car. But it does, as we all have a responsibility for the rules in Sweden. 

“We are not looking to hunt down individual Tesla owners. Rather, this is a way to spread opinion and increase pressure on Tesla. It should have some impact if several Tesla owners come in and say that you should sign a collective agreement,” one of the protesters stated.
