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.

Global renewable developer and energy giant RWE has halted its US offshore wind operations “for the time being” because of the “political environment” the Trump administration has created.
RWE, Germany’s biggest electricity producer, said in March that it had dialed back its US offshore wind activities. But now, CEO Marcus Krebber said in a speech transcript, which he’ll deliver at the company’s Annual General Meeting in Essen on April 30, that its US offshore wind business is now closed (but it wasn’t all bad news):
In the US, where we have stopped our offshore activities for the time being, our business in onshore wind, solar energy, and battery storage has so far been developing very dynamically. At the start of this year, we reached an important milestone when our US generation capacity hit the 10 gigawatt mark. The construction of a further 4 gigawatts is secured.
He went on to say that renewables have created regional value and jobs, but that the company remains “cautious given the political developments.” RWE has introduced more stringent requirements for future US investments:
All necessary federal permits must be in place. Tax credits must be safe harbored and all relevant tariff risks mitigated. In addition, onshore wind and solar projects must have secured offtake at the time of the investment decision. Only if these conditions are met will further investments be possible, given the political environment.
About half of RWE’s installed renewable capacity is in the US, where it’s the third-largest renewable energy company through its subsidiary, RWE Clean Energy. RWE holds the rights to develop US offshore wind projects in New York, Louisiana, and California.

RWE paid $1.1 billion for the New York lease area in 2022, where it’s meant to develop the 3 gigawatt (GW) Community Offshore Wind with the UK’s National Grid. Community Offshore Wind was projected to come online in the early 2030s and expected to power more than a million homes.
The developer paid $5.6 billion for the Louisiana lease in the Gulf of Mexico in 2023 as the lone bidder for development rights, and the Canopy Offshore Wind project off Northern California was not expected to be completed for another decade.

WASHINGTON – President Donald Trump and his allies have raked in nearly $900,000 in trading fees over the past two days from the president’s $TRUMP cryptocurrency token, according to Chainalysis, a blockchain data company.
The surge came after a Wednesday announcement in which the top 220 holders of the token were promised dinner with the president.
“Have Dinner in Washington, D.C. With President Trump,” reads a message on the front page of the Trump coin’s website. The event, which is black tie optional and hosted at the president’s private club in the Washington area, is scheduled for May 22, with a reception for the top 25 holders. A “VIP White House Tour” will take place the following day, the site says. The website also hosts an active leaderboard displaying the usernames of top buyers.
The $TRUMP memecoin jumped more than 50% on the dinner news, boosting its total market value to $2.7 billion. It was met with fierce criticism from some of Trump’s political opponents who said the move was further evidence that the president was using crypto to enrich himself. Sen. Chris Murphy, D-Conn., a prominent Trump critic, wrote on X that the sale was “the most brazenly corrupt thing a President has ever done. Not close.”
Roughly 80% of the $TRUMP token supply is controlled by the Trump Organization and affiliates, according to the project’s website. Since its launch in January, trading activity has generated about $324.5 million in trading fees for insiders, Chainalysis found. These fees are generated through the token’s built-in mechanism that routes a percentage of each trade to wallets controlled by the project — wallets that, according to the website, are linked to the coin’s creators.
Memecoins, often referred to as meme tokens, are a subset of digital assets that use blockchain technology and derive their value largely from internet culture, memes and social media hype rather than from an underlying utility or asset. The originators of memecoins can make fees when their coins are bought and sold.
They have grown in popularity in recent years as speculative assets, with some coins including dogecoin and fartcoin amassing total market values in excess of $1 billion.
Most of the $TRUMP supply remains locked under a three-year vesting plan, with coins gradually becoming available over time. Lockups like these are meant to protect investors by preventing insiders from cashing out all at once — a scheme commonly known in the crypto world as a “rug pull.” Vesting schedules aim to give retail buyers confidence that early holders won’t overwhelm the market and tank the token’s value.
Still, the dinner contest is being viewed by critics as an unusually explicit attempt to monetize presidential access.
As CNBC reported Friday, Democratic Sens. Adam Schiff of California and Elizabeth Warren of Massachusetts are urging the U.S. Office of Government Ethics to investigate whether the promotion constitutes “pay to play” corruption.
The White House did not respond to a request for comment. The company behind the memecoin also did not respond to a request for comment.
Delaney Marsco, the director of ethics at the Campaign Legal Center, a nonprofit focused on campaign finance and government accountability, told NBC News the coin and dinner contest amounted to an unprecedented ethics breach — though it is unlikely to be illegal.
“Criminal conflicts of interest statutes don’t apply to the President,” she said. “That has allowed him to go against decades of of norms that every modern president since Carter has adhered to, which is to divest your financial interests, rid yourself of your businesses, and kind of go in to the presidency with a clean financial slate so that no one could accuse you of manipulating policy decisions or using your position in order to enrich yourself.”
“The fact that he is not barred by the law from having these financial interests like this meme coin allows him to engage in a lot of seemingly corrupt activity. It has the appearance of a pay to play, so the President is apparently selling access to himself,” Marsco added.
Molly White, an independent crypto researcher, told NBC News that the leaderboard only shows top $TRUMP holders — and then only by their chosen screen name, making it difficult to identify who is paying to potentially join the dinner.
Schiff and Warren have cited public reports showing that some $TRUMP investors have ties to foreign exchanges or received funds from crypto platforms banned in the U.S., including Binance.
White also noted that at least one top $TRUMP owner has an account on Binance, a cryptocurrency company that doesn’t allow American users.
Trump was elected with significant help from the cryptocurrency industry, which poured tens of millions of dollars into the 2024 election, outpacing corporate donations from traditional sectors like banking and oil. After opposing digital assets during his first term, Trump pivoted in 2024 to campaign as a champion of cryptocurrency, casting Democrats as hostile to innovation and as advocating for tighter regulation.
The $TRUMP token itself offers no product or service, according to the project’s website. It is part of a broader push by the Trump family into digital assets, despite the market’s volatility and regulatory risks.
In addition to the $TRUMP and $MELANIA meme coins, the family is backing World Liberty Financial, a decentralized finance venture that has raised $550 million across two token sales since last October. Buyers are barred from reselling their tokens and receive no share of profits — but a Trump-affiliated entity is entitled to 75% of net revenue, including token sale proceeds.
Together, these projects have created new streams of revenue for Trump and his inner circle at a time when regulatory oversight of cryptocurrency has weakened sharply under his administration.
It’s that time of year again, time for events across the country to show off electric vehicles at Drive Electric Earth Month.
Drive Electric Earth Month is an offshoot of Drive Electric Week, a long-running annual tradition hosting meetups mostly in the US, but also occasionally in other countries. It started as Drive Electric Earth Day, but since not every event can happen on the same day, they went ahead and extended it to encompass “Earth Month” events that happen across the month of April. It’s all organized by Plug In America, the Sierra Club, the Electric Vehicle Association, EV Hybrid Noire, and Drive Electric USA.
Events consist of general Earth Day-style community celebrations, EV Ride & Drives where you can test drive several EVs in one place, and opportunities to talk to EV owners and ask them questions about what it’s like to live with an EV, away from the pressure of a dealership.
But the bulk of the events happened on the weekends surrounding Earth Day, April 22, so there were several last weekend and will be even more this upcoming weekend.
There are plenty of events in the big cities where you’d expect, but Plug In America wanted to highlight a few of the events in smaller places around the country. Here’s a sampling of upcoming events:
Big Island EV – Cruise and Picnic in Waimea, HI on April 26, 10am-1pm – EV drivers will congregate in various places around the Big Island (Kona, Waimea, Waikoloa and Hilo), then drive up Saddle Road to the Gil Kahele Recreation Area on Mauna Kea for a potluck and a chance to talk about the experience of owning EVs on the Big Island.
Santa Barbara Earth Day 2025 and Green Car Show in Santa Barbara, CA on April 26-27, 11am-8pm – This is part of Santa Barbara’s Earth Day celebration, which routinely attracts 30,000 participants and is one of the longest-running Earth Day celebrations on the planet. The Green Car Show includes ride & drives and an “Owners Corner” where owners can showcase their EVs and attendees can check them out and ask questions.
Earth Day’25 – EV’s role in a sustainable future in Queretaro City, Mexico on April 26, 9am-4pm – The sole Mexican event, this is a combined in-person/online seminar at the Querétaro Institute of Technology.
Norman Earth Day Festival in Norman, OK on April 27, 12-5pm – Another municipal Earth Day festival, with hands-on activities for kids to learn about the environment. A portion of the parking lot reserved for an EV car show for EV owners who pre-register to show off their vehicles.
Oregon Electric Vehicle Association Test Drive & Information Expo in Portland, OR on April 27, 10am-4pm – This one is at Daimler Truck’s North American HQ, and will have several EVs for test drives, owner displays (including DIY gas-to-EV conversions), and keynote presentations by EV experts. They’ll even have a 1914 Detroit Electric EV available for test rides!
And, we at Electrek want to give a shoutout to Rove’s EV Drive Days in Santa Ana 10am-3pm April 28 – ROVE is the company behind the “full-service” EV charging concept that we’ve talked about several times here on Electrek, and we like what they’re doing for EV charging. They’ve hosted a few community events, and this is their contribution to Earth Month.
Each event has a different assortment of activities (e.g. test drives won’t be available at every event, generally just the larger ones attended by local dealerships), so be sure to check the events page to see what the plan is for your local event.
These events have offered a great way to connect with owners and see the newest electric vehicle tech, and even get a chance to do test rides and drives in person. Attendees got to hear unfiltered information from actual owners about the benefits and trials of owning EVs, allowing for longer and more genuine (and often more knowledgeable) conversations than one might normally encounter at a dealership.
And if you’re an owner – you can show off your car and answer those questions for interested onlookers.
To view all the events and see what’s happening in your area, you can check out the list of events or the events map. You can also sign up to volunteer at your local events, and if you plan to show off your electric car, you can RSVP on each event page and list the vehicle that you plan to show (or see what other vehicles have already registered).
