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 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.
