Tesla CEO Elon Musk promised a “giant contract” to a nickel supplier during the Q2 2020 Earnings Call. The problem is that the company will have trouble finding an efficient and environmentally-friendly nickel mine, and it could prove to be Tesla’s biggest challenge yet.
Nickel is a crucial metal in electric vehicle batteries because it can increase energy density and provide cars with more range. Musk stated during the Earnings Call that nickel-based cells are essential for the development of larger vehicles, like the Tesla Semi, for example. “Where every unit of mass that you add in battery pack, you have to subtract in cargo,” he said. “So it’s very important to have a mass efficient and long-range pack.”
Nickel-based cells would give Tesla an advantage in electric vehicle range, a category where the company already leads by a sizeable margin. However, with new vehicles on the way, cells have to be adjusted to work with specific workloads. The Semi is an excellent example of this.
Nickel could replace cobalt in Tesla’s current battery cells. Cobalt, a controversial element on its own, is responsible for stabilizing the cell and has been effective in increasing the safety of the high-energy batteries that Tesla has used. However, the mining process of cobalt is questionable, and mines which can obtain it likely are using child labor, which is highly illegal. It also is not environmentally-friendly to mine.
Tesla has taken extra steps to ensure that its cobalt suppliers are treating their workers humanely through a series of due diligence checks. Third-party companies complete random visits to these mines a few times a year to ensure that the cobalt Tesla is using in its batteries is humanely obtained.
The problem is: Nickel mining isn’t much different. Although it would be advantageous, safer, and provide more range for Tesla’s vehicles, it is tough to find nickel that is environmentally-friendly and responsibly mines. The largest nickel sources are in Indonesia, where millions of tonnes of waste are dumped into the sea, polluting coral reefs and damaging the homes of turtles.
Analysts believe that Indonesian miners will provide nearly all of the growth of nickel supplies over the next decade. With electric cars becoming more popular, batteries will be a large part of the surge in demand for the metal. Still, it is also used in everyday products, like stainless steel appliances, Financial Times says.
Other countries, like Canada and Australia, have nickel mines, but Indonesia is highly concentrated with it.
Steven Brown, a consultant and former employee at nickel mining company Vale, says that it could be challenging for customers who are environmentally-conscious to want products that contain the metal after hearing how some entities dispose of it.
“It could undermine the entire proposition of trying to sell a consumer a product that is environmentally friendly, if you have this back story,” he said.
Even though other countries have nickel available, the increased demand for EVs will require large automakers, like Tesla, to eventually have to source some of the metal from Indonesia. “At some point, it will happen where they can’t avoid Indonesian nickel,” Brown added.
Luckily, Tesla requires its sources to go through due diligence processes, and it is unlikely the company will steer away from them to obtain nickel. Of course, Tesla will benefit from having more nickel, but it has to be sourced responsibly for the company even to consider using it.
On top of that, nickel is the second most expensive metal in EV batteries. It only trails cobalt, which Tesla has worked intensively to get away from because of its environmental and humanitarian impact.
“We use very little cobalt in our system already, and that’s — that may to zero along, so it’s basically about nickel,” Musk said.
There is a delicate balance between positive environmental impact after EVs hit the road and the harmful impact sourcing some of the metals have. However, the automakers do not assume any of the responsibility for the mining companies’ process of getting rid of waste. But it is their responsibility to choose a company that decides to handle the ridding of environmentally-harming materials responsibly.
Tesla has made it a point to choose companies that share their mission for sustainability because the automaker realizes that building an electric car starts with sourcing the materials. If the materials are not responsibly obtained, then the EV isn’t as Earth-friendly as it could be.
Pius Ginting, an environmental activist, summed it up perfectly: “The net result is we have clean air in our cities — but then we destroy a rich biodiversity area.”

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
