Tesla on track to increase battery energy density by 20%, reveals Panasonic executive
Tesla’s 2170 battery cells will increase in energy density by 20% in five years, the head of Panasonic’s U.S. EV battery business said. Panasonic supplies Tesla with the cells for its mass-market Model 3, which was manufactured for the first time in 2017.
Additionally, Panasonic will work to commercialize a cobalt-free version of its batteries for Tesla “in two to three years.” Cobalt-free cells would increase the positive environmental impact of driving an electric vehicle. One of Tesla’s main goals is to phase away from cobalt batteries, which is a controversial but crucial element to EV batteries.
The move from Panasonic is unprecedented and marks the first time a cell manufacturer that provides Tesla with batteries has put definitive future targets that will ensure the company stays ahead of its competitors for years to come. Reuters initially reported the findings.
Panasonic initially manufactured the 2170 lithium-ion battery cells for the Model 3. The cells are comprised of a nickel-cobalt-aluminum, or NCA, cathode chemistry, which has extremely high energy density.
High energy density means that vehicles can have increased range per charge. But their small size allows for increased spaciousness and lighter cars. Battery packs in electric vehicles tend to make up a majority of the car’s weight.
However, the company’s intention to have a cobalt-free EV battery cell within the next two to three years would revolutionize the way cars can operate. Cobalt, while useful and crucial for element stability in EV batteries, is highly controversial because of mining practices. In the Democratic Republic of Congo, it is highly reported that many of the miners are children.
This creates issues for companies that wish to remain ethical, but require the element because it is highly-functional in batteries.
Tesla has long maintained that it uses a series of due diligence practices to ensure that the cobalt it obtains is mined responsibly. In the company’s 2019 Environmental Impact Report, it stated that “Tesla is committed to making working conditions in our supply chain safe and humane, ensuring that workers are treated with respect and dignity, and that manufacturing processes are environmentally responsible.”
Eliminating cobalt from batteries would also increase the cost-effectiveness of the manufacturing process and would decrease the cost of Tesla’s vehicles.
Panasonic has been working on cutting cobalt content in its batteries to under 5% in the NCA cathode. It also plans to continue improving the battery cells in stages, according to Yasuaki Takamoto, who is Panasonic’s U.S. EV battery chief.
At the Tesla Gigafactory in Sparks, Nevada, Panasonic will begin converting lines at the factory to boost cell energy density.
Tesla will unveil developments in the company’s battery cells on September 22 at the company’s Battery Day.
Tesla has worked diligently with battery manufacturers to develop cells that will increase efficiency and decrease environmental impact. Additionally, the company has rolled out several updates that work to increase the efficiency of its vehicles. Most recently, the company’s Model Y received an update that deactivated the passenger side air vents when the seat is not occupied, which will make small efficiency changes.
Should add a few miles of range, more in slow traffic

Tesla’s Full Self-Driving (Supervised) is heading to Czechia after the Czech Ministry of Transport recognised the Dutch RDW’s provisional type approval, making the country the seventh EU member state to clear the system for public roads. Tesla Europe announced on 21 September 2026 that “FSD Supervised is now approved in Czechia” and that rollout “will begin soon.”
The decision marks a notable reversal. Earlier in 2026, Prague had declined to automatically recognise the Netherlands’ April approval, citing concerns over speed-limit compliance, traffic-sign recognition and driver-attention monitoring, and arguing that a coordinated EU approach was preferable. Officials said months of expert review, talks with Tesla and other member states, and real-world data from countries already using the system resolved those issues.

“Safety remains the top priority,” the ministry stated.
FSD Supervised remains a Level 2 driver-assistance system: the driver must stay engaged and is legally responsible. Eligible vehicles need AI4, the company’s most up-to-date hardware version. Tesla is expected to push the feature over the air in the coming days, following the pattern seen after earlier national approvals.
Europe’s rollout began when Dutch regulator RDW issued a provisional EU type approval on 10 April 2026 after extensive testing. Mutual recognition then produced a rapid cascade: Lithuania (20 May), Estonia (29 May), Denmark (9 June), Belgium (10 June) and Slovenia (7 September). Czechia now completes that list of seven.
The approvals cover only a modest share of the EU population, but they add political weight ahead of a 6 October vote by the Technical Committee on Motor Vehicles. A qualified majority, at least 15 of 27 member states representing 65 percent of the EU population, could open the remaining markets, including large ones such as Germany, France, Italy and Spain that have so far preferred to wait for a bloc-wide decision.
For Czech Tesla owners, the immediate prize is access to the same supervised highway and city driving already available in the other six countries. For Tesla, each new market generates additional European driving data and strengthens the case that FSD Supervised can operate safely under the continent’s varied road rules. The Czech approval is therefore both a local milestone and another incremental step toward a wider European launch.
The Federal Aviation Administration (FAA) has established a Temporary Flight Restriction over SpaceX’s McGregor, Texas, rocket development and test facility, a move widely viewed as preparation for Tesla’s October 1 Roadster reveal. The restriction took effect September 18 and runs through October 2.
NOTAM FDC 6/3825 covers a 1.5-nautical-mile radius around the site near Waco and extends from the surface to 10,000 feet above ground level. The FAA cited hazards under 14 CFR 91.137(a)(3) and barred aircraft and drones from the zone. Tesla’s invitation to reservation holders already placed the event in Waco, about 20 minutes from McGregor, making the timing and location more than coincidental.

What stands out is the altitude. Typical recent TFRs at McGregor for engine static fires and component tests have used far lower ceilings, often around 2,000 feet. Raising the limit to 10,000 feet is unusually high even compared with some Starbase restrictions and signals operations that go beyond a standard ground-level engine test.
That extra airspace has fueled speculation about the long-promised SpaceX Package for the Roadster. Elon Musk has described cold-gas thrusters that could deliver sub-one-second 0-60 times and, more dramatically, brief lift-off. Reports earlier this year indicated Tesla planned a remote-controlled demonstration at McGregor in which the car would leave the ground with no one inside; spectators kept hundreds of yards away because of the noise.
The 10,000-foot envelope would give operators a large safety buffer even if the vehicle only hovers a short distance.
Tesla has not confirmed a flight demo. The company has only used the phrase “Go for launch” and posted a teaser image of the car on what looks like a launch pad. The TFR itself mentions only hazards. Still, closing airspace this high and this close to the reveal date strongly suggests the event will include more than a static display.
Whether the Roadster actually hovers on October 1 remains to be seen. What is certain is that the FAA has cleared a large vertical slice of Texas sky for whatever Tesla and SpaceX intend to show. Reservation holders heading to Waco will be among the first to find out if the car can do more than drive.

Elon Musk drops a surprise update on Boring Company’s next big dig
Musk says Boring Company could shrink the Austin to San Antonio drive to just minutes.
Elon Musk says The Boring Company is working on what he called “a simple, precursor Hyperloop” tunnel connecting Austin and San Antonio, targeting speeds above 200 mph and cutting a drive that can take up to two and a half hours down to a consistent under 30 minutes. Musk posted the idea on X Sunday, in a reply to a repost of an AI generated video imagining a science fiction future with human colonies on other worlds, which he shared with the line “This is the future we shall bring into being.”

The Boring Company’s own account picked up the idea in the same thread, adding a detail about how the trip would actually work: “Because Loop/Hyperloop is express (i.e. no intermediate stops), one could travel from an Austin parking lot to a favorite San Antonio restaurant in about 30 minutes. As long as they both have Loop stations.” That framing ties the proposed intercity link to the same station model the company already runs in Las Vegas, where riders enter the tunnel network through small, garage style stops rather than one central terminal.
This is not the company’s first run at the Austin to San Antonio corridor. Boring Company floated tunnels between the two cities as far back as 2021, and later competed for a separate San Antonio Loop project tied to the airport before that specific bid stalled. Pitches for tunnels in Chicago, Los Angeles, and a New York to Washington corridor have followed a similar pattern of big announcement without a shovel in the ground.
What is different this time is the balance sheet, especially since The Boring Company closed a 3 billion dollar funding round led by investors in the United Arab Emirates earlier this month at a valuation near 23 billion dollars, giving the tunneling company more capital to chase speculative projects than it had during its earlier Texas pitches. The company is also mid-build on two other intercity systems it has actually broken ground on, inc;luding a Nashville tunnel linking downtown to the airport, where a second boring machine finished commissioning in June, and its Las Vegas network, where the station count keeps climbing on paper faster than tunnels get dug.
That gap between announcement and execution is the reason to treat Sunday’s post as an opening bid rather than a project. A tunnel spanning roughly 80 miles between two metro areas, running at speeds Boring Company has not demonstrated over any real distance, would dwarf anything the company has built. For now, the Austin to San Antonio Hyperloop exists as a caption under an AI generated space video.
