Tesla’s potential as a future battery supplier for other automakers is being paved by the ongoing struggles of the company’s rivals today. This idea is becoming more and more feasible as more and more veteran automakers experience battery-related challenges in their respective electric car programs.
Building electric cars is no easy task. As evidenced by the issues plaguing the rollout of the mass-market Volkswagen ID.3, making good electric vehicles is not just a matter of stuffing an electric motor and batteries in an existing platform for an internal combustion car. Making EVs, especially good, high-performing ones like the Tesla Model 3, requires mastery of a different set of skills, such as software management and battery optimizations.
The latter is where a vast divide exists between Tesla and legacy automakers today. Tesla utilizes its own proprietary battery tech for its vehicles. The 2170 cells for its Model 3 sedan are even being produced at Giga Nevada, a massive factory that is poised to become one of the largest in the world by footprint once it’s completed. Veteran automakers, on the other hand, rely on suppliers such as LG Chem to supply their EVs’ batteries.
LG Chem supplies cells to several automakers, including Audi and Jaguar, whose e-tron and I-PACE both utilize the company’s batteries. Rivian, which uses 2170 cells for the R1T pickup and the R1S SUV, source their cells from the South Korean firm as well. More recently, even startup Lucid Motors, which is reportedly on the cusp of releasing its first vehicle, the Air, also announced that it would be sourcing cells from LG Chem. This is great for LG Chem, as it validates the quality and capabilities of its batteries, but it also does not bode well for all the companies looking to acquire adequate battery supply for their electric cars.
As it is, LG Chem appears to be having difficulties meeting the demand for its vehicles already. Shortages of cells from the battery manufacturer have reportedly become the cause for the recent halts in the Audi e-tron and the Jaguar I-PACE’s production. And this is just with premium-priced, mid-volume SUVs. When high-volume vehicles enter the market, such as the Volkswagen ID.3 (which also gets some of its cells from LG Chem), the South Korean firm will likely find it even more challenging to supply batteries to all its clients.
This supply issue could become a serious challenge to the electric car revolution. With this in mind, and with even more electric cars coming in the next few years, a need for another battery supplier emerges. This is where Tesla comes in. Tesla has been expanding its business to not just focus on building electric cars, as evidenced by the company’s energy and battery storage initiatives. Considering Tesla’s experience in building EVs, as well as the industry-leading quality of its batteries, the company may very well be poised to become one of the leading suppliers of cells for other electric car makers.
Interestingly enough, CEO Elon Musk has mentioned the possibility of Tesla serving as a supplier of batteries and powertrains to other automakers in the past. This was explained by Musk himself during the Q3 2019 earnings call. “It would be consistent with the mission of Tesla to help other car companies with electric vehicles on the battery and powertrain front, possibly on other fronts. So it’s something we’re open to. We’re definitely open to supplying batteries and powertrains and perhaps other things to other car companies,” he said.
Fiat-Chrysler CEO Steve Manley also suggested the idea during a Q&A session. Speaking about the company’s electric vehicle strategy, Manley mentioned that Fiat-Chrysler would likely be purchasing key electric car components from the Silicon Valley-based company. “It would be wrong of me to say no,” Manley said, adding that batteries and drivetrains will likely be among the parts that FCA will be purchasing from Tesla. The CEO also expressed the possibility of FCA acquiring a “skateboard” platform from Tesla, which it would use for its own vehicles.
Tesla is at a point where its lead in the electric car space is undeniable. The company is also at a point where its manufacturing systems are more refined than before. Tesla may thus be reaching a stage where it is large and robust enough to support other automakers that are also adopting electric cars. As veteran carmakers transition into EVs, those who can secure battery supply from Tesla will likely be the ones that will survive what could very well be a painful and costly move towards sustainability.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.
Tesla wireless charging patent revealed ahead of Robotaxi unveiling event
However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
