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 has a Cybercab problem nobody saw coming
Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.
Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”
Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.
The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.
Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.
The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.
Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
