Electrek spoke with Dr. Greg Hitz, founder and CTO at Beltsville, Maryland-based ION Storage Systems, about what solid state batteries are, why they’re considered the “unicorn” of battery technology, and why they have yet to hit the market, and how his company is working to move the needle.
Electrek: Could you explain what solid state batteries are, what they’re used for, and how they differ from lithium-ion batteries?
Greg Hitz: Solid state batteries replace the flammable liquid electrolyte in a traditional lithium-ion battery with a solid electrolyte that serves the same function. They’re generally accepted as the key to unlocking the safety and energy density required for advanced electric vehicles and electrified flight.
It’s important to note, though, that not all solid state batteries are created equal. The different materials and configurations that underlie solid state battery technologies matter for safety, performance, energy density, and manufacturability.
Electrek:Solid state batteries are often referred to as the “unicorn” of battery technology. Why is that?
Greg Hitz: It’s a great analogy – you’ve never seen a solid state battery just like you’ve never seen a unicorn. Solid state batteries have long had the potential to outperform the batteries you see in most EV’s today; longer range, shorter recharge times, they’re safer. But nobody has yet shown that solid state batteries can deliver on their performance promise without making major sacrifices during battery pack integration like heating or compression requirements and can be produced with scalable manufacturing techniques.
Electrek:Why haven’t solid state batteries taken off yet?
Greg Hitz: No solid state battery manufacturer has yet to offer a 100% solution. Looking across the industry, there are technologies that have incredible rate performance, great energy density, strong safety, scalable manufacturing, and simple pack integration, but no single product offers all of that without significantly compromising one or more of the other aspects.
This is where we think ION differs from other technologies. Our first market customer will get a battery manufactured in the US that offers 40% more energy than their current solution and meets their needs on rate performance, cycle life, and production costs, all while inherently safe.
After our first market release, our second-generation product will incorporate future developments that will hugely extend the reach of the technology: doubling energy density, increased rate performance, order of magnitude decreases in production cost, qualifying long cycle life, and all the other targets required for wider market release such as EV production.
Electrek:How could solid state batteries achieve scale?
Greg Hitz: Scaling is hard and scaling batteries is even harder.
First, you need to design your battery to use plentiful, inexpensive resources. Cobalt and nickel are expensive and hard to source. ION has developed a battery with a lithium-free anode that supports nickel and cobalt-free cathodes.
Second, and perhaps most importantly, you need to design a battery that’s suited for manufacturing. The biggest targets here are energy-per-area – because cost of production is generally a per-area basis and batteries are sold per-energy – and use of highly scaled existing processing techniques.
Third, you need to create a win-win for manufacturing partners in the ecosystem. Solid state battery manufacturing is a whole new industry and there’s no widely scaled product that exists without an industry behind it. Look at the number of component suppliers for electric vehicles or for lithium-ion batteries. Dozens of companies contribute to the production of each unit sold. That complete package doesn’t yet exist in solid state batteries.
Lastly, you have to be in production to improve your production. That’s why we’re rolling out to smaller markets before we scale to EV. The pain of early production focuses the innovation and makes our EV production stronger.
Electrek:Why have cobalt and nickel become a source of pain for battery makers, and what other obstacles are there?
Greg Hitz: The only game in town for high energy density batteries right now is a nickel- and cobalt-based chemistry. There are alternatives, though.
Auto OEMs are switching to plentiful but less energy dense lithium iron phosphate chemistries for their shorter-range vehicles. Advanced nickel- and cobalt-free cathodes – incompatible with lithium-ion – that offer higher energy density without supply chain constraints exist, and have been waiting patiently for a technology to enable them.
ION’s platform technology is uniquely enabling to these plentiful and greater energy density chemistries and has been demonstrated with these cathodes, including sulfur and high voltage spinel chemistries, to name a few.
Electrek:Where are we in sourcing minerals ethically and sustainably for solid state batteries?
Greg Hitz: Solid state batteries unlock completely new chemistries, but that opportunity has to be intentionally harnessed to move to ethical and sustainable supply chains. We’ve worked with suppliers to achieve North American mineral sourcing and are working with recyclers to plan for end-of-life.

The GV90 is set to raise the bar as the most luxurious Genesis SUV. If you thought the GV80 was impressive, wait until you see this larger, three-row electric flagship. After it was recently spotted in the US, we are getting our first glimpse of the ultra-luxe Genesis GV90’s interior.
First look at the Genesis GV90 interior in the US
Genesis previewed the flagship SUV at the NY Auto Show last March with the Neolun concept, which the brand refers to as its “ultra-luxe vision of luxury SUVs.”
It’s not only stunning on the outside, but the full-size SUV will introduce advanced new tech and upscale design features for “a whole new level of luxury.”
Drawing inspiration from Korean aesthetics, the interior is fit for royalty. The concept featured a “Royal Indigo” cashmere and a vintage-like “Purple Silk” leather. Genesis topped it off with dark-colored wood accents for an even more luxurious feel.

After it was spotted in public in California, it looks like the interior of the Genesis GV90 will retain some elements from the concept.
The new photos, courtesy of The Korean Car Blog, offer a sneak peek at what we can expect when it arrives in production form.
You’ll notice that the color scheme remains largely the same, with purple accents on the door trim, seats, and other interior elements.
The GV90 will serve as the luxury brand’s tech beacon, featuring Hyundai Motor’s latest technology and software. A 24″ infotainment system will sit at the center with navigation and voice command recognition.
It will also feature a 3D audio experience with tweeters, midrange speakers, woofers, and subwoofers strategically placed, creating an immersive audio experience. The iconic Crystal Sphere is not only a centerpiece, but it will also serve as a hi-fi tweeter speaker.
According to Luc Donckerwolke, Genesis’ chief creative officer, the concept is “the epitome of timeless design and sophisticated craftsmanship.” Do you agree?
With GV90 models now in public testing, Genesis appears to be on track to launch the flagship SUV in mid-2026. Earlier this month, we got a closer look at the exterior after it was caught testing at the Nürburgring with less camo.
More details, including prices and final specs, will be revealed closer to launch. However, it is expected to ride on Hyundai’s new eM platform, which will replace its current E-GMP.

The SEC has formally dropped its lawsuit against Binance and founder Changpeng Zhao, bringing an end to one of the last remaining crypto enforcement actions brought by the agency.
In a Thursday filing in the U.S. District Court for the District of Columbia, lawyers for the SEC and Binance jointly moved to dismiss the case, which was first brought in June 2023.
The original complaint accused the crypto exchange of violations including illegally serving U.S. users, inflating trading volumes, and commingling customer funds. The agency also claimed that Binance unlawfully enabled trading in crypto assets it viewed as unregistered securities, an argument that was also used against Coinbase, Kraken, and others under prior SEC leadership.
The dismissal marks a symbolic end to one of the most aggressive crypto crackdowns in U.S. history, and comes as the Trump administration makes a concerted effort to prove that it’s an ally to the industry. The Justice Department has already shut down its crypto enforcement team, and the Commodity Futures Trading Commission is now set to be led by a venture capitalist with close ties to crypto.
Binance is the largest digital assets exchange in the world by volume. It recently forged ties with World Liberty Financial, a project that aspires to be a crypto bank and funnels 75% of profits to entities linked to the Trump family. Binance is taking a $2 billion investment from the Emirati state fund MGX entirely in USD1, a stablecoin newly launched by the World Liberty team.
Binance and World Liberty are also deepening their footprint in Pakistan, where WLF co-founder Zack Witkoff, the son of U.S. Middle East envoy Steve Witkoff, recently struck a deal with the government. Around the same time, Zhao was appointed as an adviser to Pakistan’s newly formed Crypto Council, a state-backed body tasked with shaping national digital asset policy.
The SEC was the last major regulator still pursuing Binance after a $4.3 billion settlement with the U.S. government last year that saw Zhao plead guilty and step down as CEO, while avoiding jail time and retaining much of his wealth.
The agency’s motion to dismiss was granted with prejudice, meaning the SEC can’t refile the same claims.
Under the SEC’s new leadership, the agency has shifted away from enforcement and toward engagement and regulatory rollback. It’s held a series of roundtables led by Commissioner Hester Peirce and newly appointed Chair Paul Atkins.
The SEC has also begun dismantling key rules that once kept Wall Street on the sidelines. In January, it scrapped Staff Accounting Bulletin 121 — a controversial directive issued under former Chair Gary Gensler that forced banks to count crypto holdings as liabilities on their balance sheets. Peirce celebrated the reversal on X, posting, “Bye, bye SAB 121! It’s not been fun.”
In February, the agency followed up with new guidance indicating that it doesn’t view most meme coins as securities under federal law, providing a boon to the Trump family.
President Trump and several of his family members are closely tied to crypto ventures, including the $TRUMP token, which launched just before his January inauguration. The coin currently boasts a market cap of about $2.4 billion, with its website claiming that 80% of the supply is held by the Trump Organization and affiliated entities.
After its electric vehicle sales more than doubled in the first quarter, GM claims it’s now the “#1 EV seller” in Canada. With a full lineup of 13 all-electric vehicles, GM sold more EVs than Tesla in Canada.
GM tops Tesla to become the #1 EV seller in Canada in Q1
GM’s electric vehicle sales in Canada surged by 252% in the first three months of 2025, with new Chevy and Cadillac models driving growth.
The Chevy Equinox EV led the way with 1,892 units sold, followed by the Silverado EV with 894 units. Cadillac’s new entry-level OPTIQ had a strong showing, with 615 models sold, nearly matching the 720 units sold of its first EV, the LYRIQ.
Even the GMC Hummer EV Pickup and SUV saw more demand, with sales up 232% (186) and 88% (252), respectively.

Combined, the automaker sold a total of 5,750 EVs in Q1. According to GM, this was enough to top Tesla to become “the #1 EV seller in Canada.”
GM Canada recently posted on social media, saying, “We claimed the top spot as Canada’s #1 EV seller!” The news comes as registration data show that Tesla registered just 524 vehicles in Quebec in Q1, down 87% from the same period last year.
The steep decline in sales comes after the Quebec government paused federal EV incentives from February to April 1st. Canada also paused its iZEV rebate program in January, which offered up to $5,000 on the purchase or lease of an EV. Like the US federal EV Tax credit, it was designed to be used at the point of sale to help lower prices.

GM also registered significantly fewer Equinox and Blazer EVs in Quebec during the quarter. Despite higher year-over-year (YOY) sales, GM’s electric vehicle (EV) sales were down considerably from the over 15,000 in Q4 2024.

The American automaker will continue to expand its lineup with the launch of the new Cadillac Escalade IQL, Lyriq-V, and Visiq.
By the end of the year, we also expect to get our first look at the next-gen Chevy Bolt EV with deliveries starting in 2026.
Electrek’s Take
GM is building momentum with new models rolling out, which now cover nearly every segment. In the US, GM surpassed Ford and Hyundai Motor, including Kia, to become the second-largest seller of EVs last year.
Chevy is now the fastest-growing EV brand in the US. The new electric Equinox, or “America’s most affordable 315+ miles range EV,” as GM calls it, is quickly becoming a top seller. The Blazer and Silverado EVs are also gaining traction.
Cadillac reported its best first quarter since 2008, with retail sales increasing by 21%. After delivering the first models in Q1, the entry-level OPTIQ is off to an impressive start with 1,716 units sold.
GM will top off its US electric vehicle lineup with the next-gen 2026 Chevy Bolt EV due out later this year or in early 2026.
