Tesla’s ‘skunkworks lab’ for its custom battery cell pilot production line is growing
Tesla’s Battery Day may still be a couple of months away, but hints about the highly-anticipated event’s details are already abounding. With Elon Musk specifically mentioning that the event will be held in Fremont, and that it will include a tour of the company’s pilot battery cell production line, it appears that previous reports, which point to a “skunkworks lab” in the city, were accurate. What’s more, documents filed by the electric car maker in previous months seem to indicate that its mysterious pilot battery cell facility is growing.
Initial leaks and reports about Tesla’s mysterious “skunkworks lab” were posted as early as June 2019, with a CNBC article stating that the facility is located at Kato Road, just a few minutes away from the Fremont factory, where the Model S, Model 3, Model X, and Model Y are built. Citing former and current Tesla employees, the news agency stated that Tesla’s R&D teams were focused on prototyping and designing advanced lithium-ion batteries, as well as new equipment and processes that could usher in the mass production of the next-gen cells.
These batteries are now widely speculated to be the million-mile battery that has been mentioned by the company. The million-mile battery is a significant part of Tesla’s game plan, being the one defining factor that could help electric vehicles achieve price parity with gas powered cars, and allow battery storage devices to last decades when deployed. Amidst the wait for Battery Day, speculations are abounding that Tesla will be conducting a deep dive into its million-mile batteries during the event, similar to how Autonomy Day included an in-depth discussion on the company’s custom Hardware 3.0 computer.
As it turned out, Tesla’s skunkworks lab at Kato Road has been very busy this year. A proposal submitted last March, for example, outlines plans to redevelop the existing site by adding floors to the facility. According to Tesla, the redesigned building will be housing 45 research and development employees and up to 425 manufacturing workers that are spread through several shifts from Monday through Friday. This appears to suggest that the company, as early as March this year, was looking to ramp the battery cell output of its pilot production line.
Interestingly enough, Tesla has also been posting multiple job listings on its Careers page that were specifically focused on battery cell manufacturing. By May 2020, Tesla had posted job listings for Cell Engineers, Production Process Engineers, and Controls Engineers. A look at these listings would show references to a battery cell manufacturing operations, and as luck would have it, the posts listed Fremont, California as their location.
Further documents show that Tesla had also requested to increase its power demand by 6 MW, further hinting that activities in the site are poised to ramp soon. This proposal, based on a response from PG&E that was recently shared online, was approved.
Based on these filings and job listings, it is evident that Tesla’s pilot battery cell manufacturing line has been ramping, or at least is poised to ramp, its operations. This is particularly impressive, considering that the Kato Road facility, which reportedly hosts the company’s skunkworks lab, is a fairly small site, comprising of two buildings that cover 184,880 sq. ft. combined. This means that even in this relatively small location, Tesla has been able to create a pilot line for a new breed of batteries that can change the EV game. This is quite a significant accomplishment, considering that previous battery lines are known to consume a lot of space.
Tesla’s Gigafactory Nevada facility is the perfect example of this. Giga Nevada primarily produces battery cells, and it is poised to be one of the largest buildings in the world by footprint once it’s complete. If Tesla’s pilot battery cell production line in Kato Road is indeed fully functional and ramped, then one can only imagine how much more batteries facilities like Gigafactory Nevada can produce with the company’s next-generation technology.

Elon Musk put a number on where he thinks SpaceX’s Starship program is headed by 2030, replying on X a day after President Trump signed a memo pushing the country toward 1,000 space launches and reentries a year.
The exchange started when Aaron Burnett, co-founder of propulsion startup Mach 33, posted that “1,000 launches/reentries is the goal,” quoting White House science adviser Michael Kratsios on the newly signed National Space Transportation Policy. Burnett noted that the FAA’s own bull-case forecast reached only 385 annual launches by 2030, while his firm’s conservative model already put SpaceX alone near 940. Musk responded, “We’re aiming to reach 30+ Starship launches/day in 2030, which is ~10k annualized. Still tiny numbers compared to airplane flights!”

That figure is specific to Starship, the rocket SpaceX is still developing for orbital and lunar missions, not the Falcon 9 fleet that carries most of the company’s current launch volume. Starship has flown twice this year, a slower pace than the four and five flights SpaceX managed in 2024 and 2025. Getting from two flights a year to 30 a day is the scale of jump the new federal policy is meant to clear regulatory room for.
Trump’s memo, signed Thursday, directs agencies to identify new launch and reentry sites on federal land, including a new reentry site within 90 days, and to speed up the permitting and environmental reviews that have long slowed cadence growth. It also sets a goal of returning American astronauts to the moon by 2028 and placing initial lunar base elements by 2030, tying the launch buildout directly to NASA’s Artemis program.
SpaceX has already been pushing the FAA toward higher numbers on its own. The agency approved up to 44 annual Starship launches from Kennedy Space Center in February, on top of a 2024 review that raised the cap at Starbase in Texas to 25 a year. Those approvals cover a fraction of the 10,000 annual flights Musk is now describing, which shows how far current permitting still sits from the administration’s stated target.
The near-term test of all this is more modest. SpaceX cleared a full-duration, six-engine static fire on its next Starship vehicle this week, the last major hardware checkpoint before Flight 14, which is targeting no earlier than August 28 and is expected to attempt the vehicle’s first full orbital mission. Musk said last week that a tower catch of the upper stage is still probably months away, a reminder that the immediate roadmap remains far more incremental than the daily launch numbers he just posted.
Tesla will resolve its massive recall of nearly three million vehicles in China with stickers and a software update.
On Friday, Chinese regulators filed recall plans against Tesla, Xiaomi, Leapmotor, Xpeng, Chery, Geely, Dongfeng, Arcfox, and FAW to resolve what is essentially a carbon-copy issue throughout each of the companies’ vehicle models: emergency door release latches are simply not visible enough.

The companies will be required to add things that will make these latches, which will open the door in the event of an emergency, more visible. Of the 7 million vehicles impacted, Tesla accounts for 2,975,910 units. More than 1.9 million of those are Model Y vehicles, with the rest, just over 970,000, being Model 3s.
To resolve the issue, Tesla is going to add warning labels to the emergency latches free of charge, and then utilize an Over-the-Air update to add a post-crash window-lowering strategy, according to CNEVpost.
This massive effort to fix the all-electric Model Y and Model 3’s emergency latch system comes just months after several probes across various markets identified the trouble some had identifying this latch. Those who had gotten involved in car accidents that stripped the vehicle of its power were not aware that every Tesla has emergency door latches.
China’s State Administration for Market Regulation (SAMR) said that severe crashes that disable a vehicle’s low-voltage system could not only hinder occupants from getting out, but also make it more difficult for emergency response workers to gain entry.
SAMR is starting to tighten the regulations it has on door handles on vehicles. A new mandatory national standard will take effect for all models starting January 1, 2027, and will require all doors to be equipped with mechanical release mechanisms. This will effectively end purely electronic door handles. Models already on sale with type approval have been granted a two-year transition period, which will enable things to change until January 2029.
Tesla has officially confirmed plans to bring its all-electric Semi truck to Europe, with full specifications and market-launch details set for unveiling at the IAA Transportation trade fair in Hannover, Germany.
The event runs September 15–20, with a possible press preview on September 14. The announcement, shared via Tesla’s Semi account, marks a significant expansion beyond North America nearly nine years after the truck’s original 2017 reveal.

In the United States, the Semi’s path has been gradual. Limited pilot production and customer deliveries began in late 2022, primarily to fleets such as PepsiCo. After years of refinement, high-volume manufacturing started on April 29, 2026, at a dedicated facility adjacent to Gigafactory Nevada.
The plant targets an annual capacity of 50,000 units, though the ramp is expected to be gradual, with “many thousands” of trucks projected by the end of 2026.
Demand is building, with recent orders including 500 units for Einride (deliveries starting September 2026, serving Amazon and others) and hundreds more from operators such as WattEV. Pricing stands at approximately $260,000 for the Standard Range and $290,000 for the Long Range before incentives.
Tesla Semi pricing revealed after company uncovers trim levels
Earlier in 2026, Tesla finalized production specifications that incorporated substantial updates. In February, the company detailed two variants designed for a full 82,000-pound gross combination weight.
The Standard Range offers about 325 miles of range with a 548 kWh battery and curb weight under 20,000 pounds. The Long Range delivers roughly 500 miles with an 822 kWh pack and a 23,000-pound curb weight. Both use three independent rear-axle motors producing up to 800 kW (about 1,073 horsepower), achieve energy consumption of around 1.7 kWh per mile, and support megawatt-class charging at up to 1.2 MW—recovering about 60 percent of range in 30 minutes through the MCS standard.
Additional refinements include a roughly 1,000-pound weight reduction versus earlier prototypes, improved aerodynamics, a 48-volt electrical architecture, electric power take-off up to 25 kW for refrigerated trailers, and fleet management software with over-the-air updates.
These advances position the Semi as a competitive option against diesel trucks on operating costs and performance. For Europe, adaptations such as lighting, cab configurations (including potential sleeper options), and regulatory compliance are anticipated.
With series production underway in Nevada and major fleet commitments secured, the upcoming IAA reveal will clarify timelines, European-specific specs, and pricing, potentially accelerating electrification of heavy-duty freight on both continents.
