Tesla supplier sheds light on graphite supply challenge for EV battery manufacturers [Editorial]
Graphite is an essential part of a lithium-ion battery. There are many challenges that EV battery manufacturers might face in the graphite market as electric vehicle demand continues to rise.
Graphite is often an overlooked essential mineral when people think of EV batteries. However, it is a crucial component in the anodes of lithium-ion batteries used in electric vehicles.
Graphite and Transparency
The chief executive of Syrah Resources, Shaun Verner, shared a bit about graphite pricing and funding for new projects. Syrah Resources is an Australian company that supplies Tesla from its mine in Mozambique, one of the largest graphite producers.
Verner commented that the graphite market lacks transparency when it comes to pricing, leading bankers to hesitate when it comes to funding new graphite-related projects.
Only a handful of countries mine graphite and even fewer refine the mineral enough to be used in batteries and other products. With few producers in the graphite industry, graphite consumers enter into long-term bilateral supply agreements with little transparency on prices. In addition, relatively few analysts follow the graphite industry, making it difficult to get any long-term forecasts on graphite prices.
“The single biggest impediment to new investment is the opaque nature of the market because to get the commercial debt in place is really challenging,” said Verner.
Graphite Supply
Graphite prices have declined in recent months compared to the highs in early 2022. Fastmarkets reported that traditional graphite applications have decreased this year, resulting in “sluggish” conditions in the market. However, graphite demand is expected to rise in the next few years due to growth in the electric vehicle sector.
“Graphite has kind of been the poor cousin of the battery minerals and doesn’t get the attention of the other commodities,” commented Gregory Bowes, executive chairman of the Northern Graphite Corporation. “But we’re getting very close to an inflection point where demand overtakes supply and this is going to be first page news.”
Experts observing the graphite market expect graphite supply to hit a deficit as EV battery makers increase production. Fastmarkets estimates that natural graphite consumption would rise 40% year on year, on par with the EV sector. Benchmark Mineral Intelligence had the same forecast and calculated that graphite supply would hit a deficit of 20,000 tons in 2022.
China’s dominance in the graphite industry factors into the forecasted deficit since it dominates the graphite market. In 2021, China produced 820,000 metric tons (MT) of graphite, a significant increase compared to the previous two years. The US Geological Survey reported that China accounted for 79% of the world’s graphite mining last year. The country’s quick recovery from COVID-19 shutdowns contributed to its dominance in 2021.
“Chinese producers quickly increased production after a few months of closures in 2020. This allowed China to gain a more dominant position in the market for 2021 and slowed down the diversification of the supply chain,” noted the US Geological Survey’s report.
After China, Brazil and Mozambique are the next largest graphite producers. Brazil produced 68,000 MT last year, while Mozambique’s output was 30,000 MT. Russia, Madagascar, Ukraine, Norway, Canada, India, and Sri Lanka make up the remaining Top 10 countries that produce graphite.
Graphite and the Inflation Reduction Act
The graphite industry might be a major challenge for automakers seeking to launch their products in the United States over the next few years. The recently passed Inflation Reduction Act included EV tax credits that could go as high as $7,500 for automakers that adhere to a few specific requirements.
One of the requirements to qualify for the EV tax credit is related to batteries and the minerals used to make them. According to the Inflation Reduction Act, at least 40% of the critical minerals used to make US-made EV batteries must also come from US miners or recycling plants. Automakers can also qualify for the tax credit if the minerals used in their US-made batteries come from countries with free trade deals with the United States.
In 2021, natural graphite was not produced in the United States, but it consumed 45,000 tons of the mineral, estimated to be worth $41 million. The United States imported about 53,000 tons of graphite last year, mainly from China. It also imported graphite from Mexico, Canada, India, and other sources.
US Geological Survey mentioned one US automaker in its report about graphite imports. It did not mention the automaker by name.
“A US automaker continued building a large plant to manufacture lithium-ion electric vehicle batteries. The completed portion of the plant was operational, and it produced battery cells, battery packs, drive units, and energy storage products. At full capacity, the plant was expected to require 35,200 tons per year of spherical graphite for use as anode material for lithium-ion batteries,” stated the report.
Eric Desaulniers, the chief executive of Nouveau Monde Graphite, stated that discussions with cell manufacturers have ramped up after the Inflation Reduction Act was passed. Nouveau Monde is currently developing a graphite mine and battery-grade anode plant in Canada.
Desaulniers noted that challenges are ahead when it comes to securing project financing since “cell makers are cash-constrained.” He also noted that automakers had their hands full from scaling up their respective battery manufacturing facilities.
Tesla, considered the lead electric vehicle manufacturer in the United States, is already producing its 4680 battery cells in California. Rivian, General Motors, and other automakers also plan to develop their own battery cells in their own battery manufacturing plants.

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.
