Researchers at Harvard University have developed a solid state battery that can be recharged in 10 minutes, and now it’s got Series A funding to scale production.
October 23 update: Adden Energy has raised $15 million in a Series A round led by At One Ventures with participation from Primavera Capital Group, Rhapsody Venture Partners, and MassVentures to scale production and bring solid state battery technology to car manufacturers.
The company will use the funding to construct a roll-to-roll pilot line production facility at its headquarters in Waltham, Massachusetts.
Adden Energy has already demonstrated technology that can deliver its battery in EV-compatible, commercially compatible pouch cell form-factors; this Series A-funded production line will enable it to scale the size of the batteries 100x.
Laurie Menoud, partner at At One Ventures and board member at Adden Energy, said, “Our investment in this technology is a signal of how important we know this to be, and it’s also our confidence level in Adden Energy’s ability to win market share through competitive unit economics. With the added energy density of lithium metal anodes, the cost per kilowatt hour is going to drop by 30%, and that is going to be a significant driver of adoption.”
Adden Energy says its next-generation batteries are on track to reach the goal of EV parity with internal combustion engines by 2028.
Harvard’s latest solid-state battery breakthrough
January 15, 2024: The lithium metal battery researchers developed at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) can also be charged and discharged at least 6,000 times — more than any other pouch battery cell.
The research published in Nature Materials describes a new way to make solid-state batteries with a lithium metal anode. Xin Li, Associate Professor of Materials Science at SEAS and senior author of the paper, said:
Lithium metal anode batteries are considered the holy grail of batteries because they have ten times the capacity of commercial graphite anodes and could drastically increase the driving distance of electric vehicles.
Our research is an important step toward more practical solid-state batteries for industrial and commercial applications.
One of the biggest challenges in designing solid-state batteries is the formation of dendrites on the surface of the anode. Dendrites are projections of metal that can build up on the lithium surface and grow like roots into the electrolyte. They pierce the barrier that separates the anode and cathode, causing the battery to short or even catch fire.
The dendrites form when lithium ions move from the cathode to the anode during charging, attaching to the surface of the anode in a process called plating. That creates an uneven, non-homogeneous surface on the anode, and allows dendrites to take root.
When discharged, that plaque-like coating needs to be stripped from the anode, and when plating is uneven, the stripping process can be slow and result in potholes that induce even more uneven plating in the next charge.
In 2021, the team designed a multilayer battery that sandwiched different materials of varying stabilities between the anode and cathode. This design prevented the penetration of lithium dendrites by controlling and containing them – but it didn’t stop them altogether.
But in this latest research, the researchers stop dendrites from forming by using micron-sized silicon particles in the anode to constrict the lithiation reaction and facilitate homogeneous plating of a thick layer of lithium metal.
In the Harvard researchers’ design, when lithium ions move from the cathode to the anode during charging, the lithiation reaction is constricted at the shallow surface and the ions attach to the surface of the silicon particle, but don’t penetrate further.
“In our design, lithium metal gets wrapped around the silicon particle, like a hard chocolate shell around a hazelnut core in a chocolate truffle,” said Li.
And, because plating and stripping can happen quickly on an even surface, the battery can recharge in about 10 minutes.
The researchers built a postage stamp-sized pouch cell version of the battery, which is 10 to 20 times larger than the coin cell made in most university labs. The solid-state battery retained 80% of its capacity after 6,000 cycles, outperforming other pouch cell batteries on the market today.
Harvard Office of Technology Development licensed the technology to Adden Energy, a Harvard spinoff company cofounded by Li and three Harvard alumni. Adden Energy has scaled up the technology to build a smart phone-sized pouch cell battery.
Electrek’s Take
This is yet another milestone achieved in the solid-state battery saga. The ultimate challenge is still bringing them to mass-production at a lower price than lithium-ion batteries. That will be the real game-changer for EVs.

Back in 2018, when most electric motorcycle startups were showing off what looked like clunky science experiments or budget-minded e-scooters, a little company out of Stuttgart quietly unveiled one of the wildest-looking two-wheelers I’d ever seen. As one of the first motorcycle journalists to cover Sol Motors and their outlandish debut seven years ago, I’ve been keeping tabs on them ever since. And now I am excited to share that the Sol Pocket Rocket is finally preparing to launch in full production form. Yes, really.
The German company is now taking pre-orders for its uniquely tubular electric motorcycle that somehow looks like a mashup between a torpedo, an irrigation pipe, and a Star Wars prop. And yet, despite its cartoonish silhouette, it might just be one of the coolest ultra-urban e-motos headed for the streets.
The Sol Pocket Rocket comes in two versions: the standard model and the more powerful Pocket Rocket S. The latter packs an 8.5 kW (roughly 11.4 hp) electric motor that propels the bike to a top speed of 85 km/h (53 mph), while the standard version tops out at 45 km/h (28 mph), putting it in moped territory in many markets.
That makes it a perfect fit for cities, especially in Europe where light electric mopeds and motorcycles are gaining traction among young riders who want something fast, fun, and emissions-free, but without the size, weight, or cost of a traditional motorcycle. The bike’s 2.5 kWh battery may not sound like much, but the company says it offers up to 108 km (67 miles) of range for the lower speed version or 68 km (42 miles) of range for the higher speed version, which is generally more than enough for most urban commutes. The battery is also removable, allowing for convenient charging inside your apartment or office. That can be a neat trick for riders who charge at work, essentially doubling the maximum range they can commute.

And while we’re on the topic of design – yes, it’s unusual. The Pocket Rocket’s oversized aluminum top tube houses the battery and electronics, while a minimalist seat juts out from the back like a café racer’s rear hump. There’s no bodywork to speak of, giving it a raw and industrial aesthetic that’s either futuristic or ridiculous, depending on the lighting and your mood. But I’ve got to admit, I kind of love it.
The frame, wheels, and swingarm are all nicely machined, giving the whole thing a premium feel, or at least as premium as a potato gun on wheels can look. It’s like if Bauhaus made a Hot Wheels bike that could run on electrons.
Sol Motors is positioning the Pocket Rocket not just as a stylish e-motorcycle, but as a viable alternative to cars for city dwellers who want to skip traffic and parking headaches. It’s light, fast enough for urban streets, and small enough to squeeze into even the tiniest bike parking spot.
Pre-orders are now open and pricing starts at €5,990 for the standard model and €6,980 for the S version. That’s certainly not cheap, but not outrageous in today’s market for well-designed, European-made electric two-wheelers.
Electrek’s Take
I’ve covered a lot of oddball EVs over the years, but the Sol Pocket Rocket has a special place in my heart. There’s something honest about a company that doubles down on such a bold design and actually makes it work. Sure, it looks like a giant spool holder from the wrong angle, but it also looks like a lot of fun from the right angle! And the fact that it’s fast, fun, and actually headed to production means it offers three things that are far from a guarantee in today’s market.
It may have taken the scenic route and had a false start or two, but it looks like the company is finally ready to put that rubber on the road for good this time.
After nearly seven years of anticipation, I’m thrilled to see this bizarre beauty finally hitting the road. And hey, if anyone wants to send one over for a review, my driveway’s been waiting just as long.
They even have this cool charging stand for topping up the battery in your apartment

Chevy is introducing an updated lineup for the 2026 Blazer EV, including a few slight modifications. Despite the changes, prices will still start at under $45,000.
Although the Equinox EV stole the spotlight, becoming the third top-selling EV behind Tesla’s Model Y and Model 3, Chevy’s electric Blazer has quiety been driving growth. In April, the Chevy Blazer EV was the sixth-best-selling EV.
With “the Equinnox and Blazer right in the heart of the market, they are really benefitting from that,” Tom Libby, an analyst at S&P Global Mobility, explained.

With the 2026 model years arriving with a few updates, Chevy looks to continue closing the gap with Tesla. Earlier this month, the 2026 Chevy Silverado EV configurator went live with base prices about $10,000 cheaper than the outgoing model. Now, it looks like the electric Blazer will be next.

New order guide data show the 2026 Chevy Blazer EV LT FWD will still start at $44,600, not including the destination fee. The 2026 model year will be available in FWD, AWD, and performance AWD configurations. However, Chevy is dropping the RWD option.
Although the base LT model is priced the same, the 2026 Chevy Blazer RS AWD is $500 more than last year’s model, starting at $50,400.

The 615 horsepower Blazer EV SS, the quickest SS Chevy vehicle to date, will still start at $60,600. Like the 2025MY, GM’s Super Cruise is standard on the SS and available for other trims. It costs $3,255 this year, the same as it did in 2025.
Other upgrades for the new model include a new Polar White Tricoat paint option and a standard dual-level charging cord, but it still lacks a NACS port.

A Chevy spokesperson confirmed to Car and Driver last month that “To simplify the product lineup while still offering the most popular options for consumers, RWD will not be available beginning with the 2026 model year.”
Up next will be the 2026 Chevy Equinox EV, or “America’s most affordable 315+ mile range EV,” as GM calls it. The base 2025 LT model starts at $34,995. Chevy keeping entry-level Blazer prices the same could be a good sign for the Equinox.

Tesla has expanded the service area of its Robotaxi service in Austin, and it did so to draw a penis-shaped service map, seemingly for no other reason than to satisfy the juvenile humor of its CEO, but what it really achieved is to illustrate how unserious Tesla’s Robotaxi business is compared to other efforts.
The service was launched only for a small group of Tesla stock promoters on X, and it required a Tesla employee sitting in the front seat with a finger on a kill switch at all times.
In other words, it’s basically Tesla’s Supervised Full Self-Driving (FSD) in consumer vehicles, but with the supervisor moved from the driver’s seat to the front passenger seat.

Tesla also launched into a small area of South Austin, but last week, Musk said that the company would expand the service area by the weekend.
Late on Sunday, Tesla did update the service area, and it now looks like this:
There’s no practical reason to cover this specific section of Austin. The update appears to be solely to satisfy Musk’s famously juvenile sense of humor, which includes fascinations with the numbers “69” and “420”.
Tesla has also been offering rides in Robotaxi (invite-only) for $4.20 a ride.
In practice, what this joke does is illustrate just how unserious Tesla’s Robotaxi effort is in comparison to other autonomous ride-hailing programs.
Waymo already operates a larger area of Austin, and it does so without any supervisor inside the vehicle. It also operates in San Francisco, the Bay Area, Los Angeles, and Phoenix:
Tesla shareholders are holding on to the hope that Tesla will be able to scale faster, but Waymo has even launched in Atlanta since Tesla launched its limited service in Austin, and they are preparing to launch in Philadelphia and New York.
Meanwhile, Tesla still operates with supervisors inside its vehicles – a step that Waymo completed years ago.
Electrek’s Take
Look, I love a joke as much as the next guy, but when the whole service is a joke, maybe don’t draw a penis with the service map.
In China, I rode in Baidu’s Apollo Go, and it simply works without anyone in the car, and it is in operation in half a dozen cities.
It’s cool to see Tesla making progress here, but what’s less cool is the moving of the goalpost that leads to people forgetting that Tesla has promised unsupervised self-driving in all vehicles built since 2016.
Meanwhile, its progress has yet to outpace competition and CEO Elon Musk is out there claiming Tesla is the leader in self-driving with no close second.
It’s a level of delusion that you don’t want to see in someone deploying “self-driving” 5,000-lb machines moving at high speeds on public roads.
