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 shows what Roadster drivers will see on screen before thruster activation
Tesla’s Roadster video reveals a fighter jet inspired cockpit with a 5,500 PSI thruster gauge.
Tesla has given future owners their clearest look yet at the cockpit of its next generation Roadster. In a 34 second video posted to X on Friday afternoon, the company walked through the car’s touchscreen with a caption: “Inspired by fighter jet cockpits, Roadster’s interface was designed around the pilot.”
The clip opens on a black screen with red graphics and a 3D wireframe of the car, which sits beside the Roadster’s squared off yoke. Tapping parts of the model brings up controls for the rear wing, including low drag and high downforce positions, along with a charging page with a charge limit bar and a small music player. A row of tabs along the bottom reads Home, Vehicle, Listen, Climate and Navigate.
Most of the video is spent in Track Mode. The dashboard shows a live circuit map, a list of session lap times, brake and motor temperatures, and pressure and temperature readouts for each tire. A setup page lets the driver pick Auto, Low Drag, High Downforce or Custom aero modes, adjust aero balance and brake balance, and switch stability and traction control off. Along the bottom, a status bar reads “Thruster · 5,500 PSI” next to a “Boost Ready” indicator.
That gauge ties the software to the hardware Tesla showed off near Waco, Texas on October 15. The Thrust and Rocket versions use cold gas thrusters fed by carbon overwrapped pressure vessels, and Tesla lists 0 to 60 mph times of under 0.9 seconds and under 0.59 seconds for them, as Teslarati detailed in its breakdown of the three Roadster configurations. The base Performance car relies on a fan and ground sealing system for grip, and the aero settings on screen match the active wings and suction setup covered in our look at how the Roadster generates downforce.
The Roadster layout is a departure from the rest of Tesla’s lineup. Instead of a map centered screen, the Roadster puts the car itself at the center of the home page, and Tesla’s Roadster page lists two smaller forward displays alongside the main touchscreen. Tesla has not said whether any of the Track Mode telemetry will make its way to the Model 3 Performance or other vehicles.
The interface could still change before deliveries. Elon Musk said at the event that Roadster production will begin in 2028, and Tesla says the flagship Rocket version is not approved for public road use. Reservations are open with a $50,000 payment, while Thrust is listed as a limited release and Rocket is invite only.
Those who want to see the car in person will get their first chance this weekend. The Roadster goes on display in the lobby of the Petersen Automotive Museum in Los Angeles from October 24 to 27, according to Sawyer Merritt, the first time the public will be able to view it up close.

Tesla reveals Optimus Academy, where robots teach themselves
Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.
Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”
The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.
Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.
The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.
Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.
The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.
Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.

The Starship moon landing number NASA and Elon Musk can’t agree on
Musk disputes NASA estimate of 22 Starship launches for Moon landing, predicting 6 to 8.
Elon Musk is disputing a new NASA safety panel estimate of how many Starship launches it will take to put astronauts on the Moon, saying the real number will be less than half the panel’s figure.
On Thursday, NASA’s Aerospace Safety Advisory Panel held its quarterly public meeting. Panel member Charlie Precourt, a former NASA astronaut, flagged the fueling process for SpaceX’s lunar lander as a major risk for Artemis IV, the mission planned to land a crew on the Moon in 2028. “We need to keep our eyes on numerous required fuelings for the lander,” Precourt said, according to Ars Technica. “I think the last estimate is around 22 flights.”
Ars Technica’s Eric Berger posted the comment on X, and Musk replied. “That’s way too high,” Musk wrote. “Actual number will be more like 6 to 8.”
The disagreement comes down to a basic problem with sending a ship as large as Starship to the Moon. Starship burns nearly all of its propellant just reaching Earth orbit, so it cannot continue on to the Moon without stopping for a refill. SpaceX’s answer is a gas station in space. First, a Starship that works as a storage tank, called a depot, is launched into orbit. Then a series of tanker Starships launch one at a time, dock with the depot and pump their leftover propellant into it. Once the depot is full, the lunar lander version of Starship launches, docks, fills up and heads for the Moon.
Every tanker trip is its own full rocket launch, which is why the count matters. More launches mean more time, more cost and more chances for something to go wrong before astronauts ever leave Earth. Berger estimated that even if SpaceX reaches twice weekly Starship launches by the end of 2027, filling a depot at the panel’s number would still take roughly three months.
How many tankers are needed depends mostly on how much propellant each one can carry to orbit and how much is lost along the way. Starship’s fuel and oxygen are stored at extremely cold temperatures, and some of it slowly boils off while waiting in orbit. More is lost in each transfer. NASA appears to be working from what Starship can lift today, while Musk’s range assumes a more capable rocket.
Musk has pushed back on higher counts before. In 2021, after a government document suggested 16 launches, he called that “extremely unlikely” and said eight tankers would be the most required.
Much of the answer depends on hardware SpaceX has not finished flying. As Teslarati noted earlier this year, the company plans to carry out the refueling process with its upgraded V3 Starship, and Precourt described Artemis IV as carrying “a large number of firsts.” He also praised NASA Administrator Jared Isaacman’s team for working to clear obstacles for both SpaceX and Blue Origin, whose Blue Moon lander does not rely on orbital refueling for its first mission.
