Tesla is building a lithium hydroxide refinery in Texas for its Cybertruck factory
A recent report from market intelligence publisher Benchmark Mineral Intelligence has revealed that Tesla is poised to build a lithium hydroxide chemical plant in Texas. The lithium hydroxide refinery will reportedly be situated in Texas, and it will be used to feed the upcoming Cybertruck Gigafactory.
The spodumene conversion facility will be built adjacent to Gigafactory Texas, and based on Benchmark Minerals’ report, the facility has a target date of Q4 2022 for its start of operations. This is a notably aggressive timeframe for such a facility, though it is something distinctly Tesla. Ultimately, the lithium hydroxide refinery will add to Tesla’s plans to set up a cathode facility in Texas, which Elon Musk has described as part of the electric car maker’s cell production plan.
The upcoming conversion/refining plant will turn hard rock spodumene ore into lithium hydroxide, which is used directly in battery cells. It should be noted that prior to Tesla’s battery efforts, this process has traditionally been performed in China using spodumene that’s sourced from Australia. In its report, Benchmark Minerals noted that Tesla will be using a hydrometallurgical process to turn its spodumene ore into lithium hydroxide, effectively eliminating the use of sulphuric acid. This process, however, remains untested in the commercial scale.
Interestingly enough, a recent announcement from Australian mining firm Piedmont Lithium has revealed that Tesla has signed a five-year deal to acquire spodumene from a mine in North Carolina. In its press release, Piedmont noted that its Tesla deal represents about one-third of the expected 160,000 tonnes per annum that’s expected to be produced at its North Carolina mine. This deal will likely supply Tesla with 8,000 tonnes of lithium hydroxide a year, starting between July 2022 and July 2023.
In its report, Benchmark stated that the Piedmont Lithium deal will likely account for just over half of Tesla’s battery needs for Gigafactory Texas in 2023, the first estimated full production year of the electric car maker’s 4680 cells. With this in mind, Tesla would still need to secure more spodumene supply beyond Piedmont Lithium’s capabilities, especially if the company intends to fully ramp its battery cell production capabilities. Benchmark Mineral Intelligence Managing Director Simon Moores, for his part, highlighted the significance of Tesla’s battery production push.
“Lithium’s foundations for the 21st century are beginning to shift in what is a China-dominated part of the lithium-ion battery and electric vehicle supply chain. Tesla is the first automotive OEM to enter lithium production – a watershed moment. And it does so without having to mine lithium from the ground. Not only will it allow Tesla to control costs at this supply chain step, it will once again see the spodumene trade flows point towards the USA instead of China, a market that has dominated spodumene conversion for a generation through majors such as Tianqi and Ganfeng Lithium.
“It will also significantly bolster its negotiating power on its future lithium hydroxide contracts once it harnesses the ability to produce a consistent battery ready lithium hydroxide and scales capacity. Tesla has clearly come to the realization that it cannot rely on the upstream of the supply chain or investors to expand quickly enough for its needs. It has now taken some of that responsibility away from the miners and chemical producers and once Tesla gets to grips with the lithium refining process, scale will be introduced and we expect that post-2022 ramp to be rapid,” he said.
Benchmark Mineral Intelligence Product Director Andrew Miller added that Tesla’s lithium hydroxide chemical plant in Texas will allow the electric car maker to closely monitor the cost and quality of its batteries’ components. Miller added that Tesla’s efforts to move upstream in the battery supply chain will likely be replicated by other carmakers in the future.
“With Tesla entering the upstream of the lithium-ion battery supply chain at the conversion stage the company does not have to become a lithium miner, a skill-set and company culture that is entirely different to creating chemically refined materials. Controlling the lithium conversion from the raw material – spodumene concentrate – means they can not only reduce the cost but also control the quality of the lithium hydroxide output more closely.
“This is additional evidence that lithium will remain a specialty chemical that is tied to and tailored for the needs of the end-users, rather than a commodity. In addition, Tesla’s efforts to move upstream will likely be replicated by other auto manufacturers, and in other areas of the supply chain. Having control of advanced material costs into the EV supply chain is an increasingly important factor in lowering battery prices,” he said.

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.
