Chicago-headquartered NanoGraf Technologies, which claims it has enabled the highest energy-density cylindrical 18650 Lithium-ion cell in the world, today announced that its battery has achieved a new industry energy-density milestone of 810 Wh/L (4.0Ah capacity).
Ampere hours (Ah) is the amount of energy charge in a battery that enables 1 ampere of current to flow for one hour.
In 2021, NanoGraf announced it had developed the world’s longest-running 3.8Ah 18650 cylindrical lithium-ion cell, at 800Wh/L, so this latest version reflects an improvement.
NanoGraf says in a statement that “the increased stability and highly scalable nature of [its new] silicon-anode cell solves the pain points of commercial first-generation SiOx anodes, and it is proven to be drop-in ready for existing cell designs and production processes.”
Techopedia explains what a silicon anode battery is:
A silicon anode battery is a type of lithium-ion battery where the anode is replaced by silicon nanotubes or silicon coating. The idea of using a silicon anode in a battery is still under a lot of testing. This has multiple advantages over ordinary lithium or graphite anodes. The silicon enables long life and high energy storage, resulting in a significantly longer lasting battery.
NanoGraf says that its “silicon-anode and 18650 cell represent a step forward in establishing a domestic battery supply chain, a key directive of the Biden administration to build US jobs, alleviate supply chain bottlenecks, and support a nationwide movement toward automotive electrification.”
Dr. Francis Wang, CEO of NanoGraf, said:
The Inflation Reduction Act calls for and supports the onshoring of key battery components in the US, and these historic opportunities are providing additional momentum around the adoption of upstream US innovation like NanoGraf’s.
NanoGraf products are important commercial examples of how US innovation can not only raise the bar on lithium-ion performance, but create US jobs and promote national security.
In 2019, the US Council for Automotive Research, a consortium of Ford, General Motors, and Stellantis, provided NanoGraf with $7.5 million for a 36-month electric vehicle battery research and development project.

The new John Deere Z370RS Electric ZTrak zero turn electric riding mower promises all the power and performance Deere’s customers have come to expect from its quiet, maintenance-free electric offerings – but with an all new twist: removable batteries.
The latest residential ZT electric mower from John Deere features a 42″ AccelDeep mower deck for broad, capable cuts through up to 1.25 acres of lawn per charge, which is about what you’d expect from the current generation of battery-powered Deeres – but this is where the new Z370RS Electric ZTrak comes into its own.
Flip the lid behind the comfortably padded yellow seat and you’ll be greeted by six (6!) 56V ARC Lithium batteries from electric outdoor brand EGO. Those removable batteries can be swapped out of the Z370RS for fresh ones in seconds, getting you back to work in less time than it takes to gravity pour a tank of gas.
When John Deere launched the first Z370R, Peter Johnson wrote that electrifying lawn equipment needs to be a priority, citing EPA data that showed gas-powered lawnmowers making up five percent of the total air pollution in the US (despite covering far less than 5% of the total miles driven on that gas). “Moreover,” he writes, “it takes about 800 million gallons of gasoline each year (with an additional 17 million gallons spilled) to fuel this equipment.”

Daimler Truck AG CEO Karin Rådström hopped on LinkedIn today and dropped some absolutely wild pro-hydrogen talking points, using words like “emotional” and “inspiring” while making some pretty heady claims about the viability and economics of hydrogen. The rant is doubly embarrassing for another reason: the company’s hydrogen trucks are more than 100 million miles behind Volvo’s electric semis.
UPDATE 22NOV2025: Daimler just delivered five new hydrogen semis for trials.
While it might be hard to imagine why a company as seemingly smart as Daimler Truck AG continues to invest in hydrogen when study after study has shut down its viability as a transport fuel, it makes sense when you consider that the Kuwait Investment Authority (KIA) holds approximately 5% of Daimler and parent company Mercedes’ shares.
That’s not a trivial stake. Indeed, 5% is enough to make KIA one of the few actors with both the access and the motivation to shape conversations about Daimler’s long-term technology bets, and as a major oil-producing country whose economy would undoubtedly take a hit if oil demand plummeted, any future fuel that’s measured molecules instead of electrons isn’t just a concept for the Kuwaiti economy: it’s a lifeline.
In that context, the push to make hydrogen seem like an attractive decarbonization option makes more sense. So, instead of giving Daimler’s hydrogen propaganda team yet another platform to try and convince people that hydrogen might make for a viable transport fuel eventually by giving five Mercedes-Benz GenH2 semi trucks to its customers at Hornbach, Reber Logistik, Teva Germany with its brand ratiopharm, Rhenus, and DHL Supply Chain, I’m just going to re-post Daimler CEO Karin Rådström’s comments from Hydrogen Week.
For some reason – posts about hydrogen always stir up emotions. I think hydrogen (not “instead of” but “in parallel to” electric) plays a role in the decarbonization of heavy duty transport in Europe for three reasons:
If we would go “electric only” we need to get the electric grid to a level where we can build enough charging stations for the 6 million trucks in Europe. It will take many years and be incredibly expensive. A hydrogen infrastructure in parallel will be less expensive and you don’t need a grid connection to build it, putting 2000 H2 stations in Europe is relatively easy.
Europe will rely on import of energy, and it could be transported into Europe from North Africa and Middle East as liquid hydrogen. Better to use that directly as fuel than to make electricity out of it.
Some use cases of our customers are better suited for fuel cells than electric trucks – the fuel cell truck will allow higher payload and longer ranges.
At European Hydrogen Week, I saw firsthand the energy and ambition behind Europe’s net-zero goals. It’s inspiring—but also a wake-up call. We’re not moving fast enough.
What we need:
Large-scale hydrogen production and transport to Europe
A robust refueling network that goes beyond AFIR
And real political support to make it happen – we need smart, efficient regulation that clears the path instead of adding hurdles.
To show what’s possible, we brought our Mercedes-Benz GenH2 to Brussels. From the end of 2026, we’ll deploy a small series of 100 fuel cell trucks to customers.
Let’s build the infrastructure, the momentum, and the partnerships to make zero-emission transport a reality. 🚛 and let’s try to avoid some of the mistakes that we see now while scaling up electric. And let’s stop the debate about “either or”. We need both.

At the risk of sounding “emotional,” Rådström’s claims that building a hydrogen infrastructure in parallel will be less expensive than building an electrical infrastructure, and that “you don’t need a grid connection to build it,” are objectively false.
Next, the claim that, “Europe will rely on import of energy, and it could be transported into Europe from North Africa and Middle East as liquid hydrogen” (emphasis mine), is similarly dubious – especially when faced with the fact that, in 2023, wind and solar already supplied about 27–30% of EU electricity.
Unless, of course, Mercedes’ solid-state batteries don’t work (and she would know more about that than I would, as a mere blogger).
Electrek’s Take
Via Mahle.
As you can imagine, the Karin Rådström post generated quite a few comments at the Electrek watercooler. “Insane to claim that building hydrogen stations would be cheaper than building chargers,” said one fellow writer. “I’m fine with hydrogen for long haul heavy duty, but lying to get us there is idiotic.”
Another comment I liked said, “(Rådström) says that chargers need to be on the grid – you already have a grid, and it’s everywhere!”
At the end of the day, I have to echo the words of one of Mercedes’ storied engineering partners and OEM suppliers, Mahle, whose Chairman, Arnd Franz, who that building out a hydrogen infrastructure won’t be possible without “blue” H made from fossil fuels as recently as last April, and maybe that’s what this is all about: fossil fuel vehicles are where Daimler makes its biggest profits (for now), and muddying the waters and playing up this idea that we’re in some sort of “messy middle” transition makes it just easy enough for a reluctant fleet manager to say, “maybe next time” when it comes to EVs.
We, and the planet, will suffer for such cowardice – but maybe that’s too much malicious intent to ascribe to Ms. Rådström. Maybe this is just a simple “Hanlon’s razor” scenario and there’s nothing much else to read into it.
Let us know what you think of Rådström’s pro-hydrogen comments, and whether or not Daimler’s shareholders should be concerned about the quality of the research behind their CEO’s public posts, in the comments section at the bottom of the page.

Audi embraced its future in China with the launch of a new Chinese market electric sub-brand called AUDI that ditched the iconic “four rings” logo in favor of four capital letters – but one thing this latest concept hasn’t ditched is the brand’s traditionally teutonic long-roof design language.
Co-developed with Audi’s Chinese production partner, SAIC, the all-new AUDI E SUV concept is based on the PPE (Premium Platform Electric) skateboard, and is only the second model introduced by the company’s domestic sub-brand — which was all-new itself just one year ago.
“The AUDI E SUV concept celebrates the new AUDI brand’s first anniversary following the E concept’s debut in Guangzhou (2024),” said Fermín Soneira, CEO of the Audi and SAIC cooperation, at the E SUV’s unveiling. “It showcases an unmistakable AUDI design language that gives the SUV a prestigious, progressive stance — with no compromise between sporty aesthetics and interior roominess or versatility. This concept embodies our vision for premium electric mobility by fusing Audi’s engineering heritage with digital innovation to fulfill our commitment in China.”
As a vehicle, the AUDI E SUV concept promises to handle “like an Audi,” and is powered by a pair of electric motors good for a combined 500 kW (~670 hp), good enough to get the big crossover from 0-100 km/h (62 mph) in about five seconds. Those efficient motors are fed electrons by a 109 kWh battery riding on AUDI’s 800V Advanced Digital Platform system architecture, and can allegedly add 320 km (~200 miles) of range in under 10 minutes at a high-powered DC fast charging station.
