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.

Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it
— Elon Musk (@elonmusk) October 3, 2026
The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.
Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.
An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.

The Tesla employee would walk around and plug each car in, adjusting the parking if needed:
So look at what I found. This is how Tesla charges unsupervised robotaxis at a public supercharger. Here is a driverless Cybercab showing up with no one in it. There are 9 other Model Ys that showed up too. A Tesla employee is walking around and plugging each of them in. She also moves the cars if they are not positioned well enough to charge. I love this process. One person charges multiple robotaxis at once

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.
On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.
However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.
@Teslarati Sheer magnitude of the entire production system is hard to appreciate. Almost every element of production is >75% automated. Only wire harnesses & general assembly, which are <10% of production costs, are primarily manual.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.
Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.
CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.
The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.
In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.
The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.
Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”
Robotaxi operating hours moved from 10pm to 11pm.

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.
Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.
The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.
Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.
The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
