Toyota joins race to try and bring solid-state batteries to mass production
Toyota Motor Company is the latest automaker delving into solid-state battery technology, vowing to mass-produce the safer and more energy dense cells in the next four years. In typical Toyota fashion, the Japanese automaker continues to smell its own farts, declaring that it and its new battery partner Idemitsu already “lead the world” in solid-state battery material development. Slow down there, guys…
Toyota Motor Company, which is hilariously describing itself as on a multi-pathway approach to promoting BEV development, is suddenly touting its solid-state battery development, which has been in the works as far back as 2006.
That’s interesting to hear, given the Japanese automaker’s publicly announced doubt in EV adoption during that time span, although it has recently changed its tune about building BEVs. It’s almost like they peaked outside their of gassy, hybrid-powered bubble and noticed everyone else is going electric. Weird!
In all seriousness, Toyota has taken a Dom Toretto-style drift into BEV development, quickly refocusing its resources and assembly lines to produce a new line of all electric vehicles and… compete with Tesla? Good luck…
Although it’s been off to a rocky start in the EV world, Toyota does remain one of the largest automakers on the planet, and has the resources to accelerate EV production quicker than most of its competitors. Toyota probably should have started in 2006 alongside the solid-state battery research, but hey, better late than never.
Today, the automaker announced a new partnership with fellow Japanese company Idemitsu Kosan to bring viable solid-state batteries to full-scale production by 2027.
Toyota and Idemitsu to develop solid-state batteries
Today’s partnership announcement follows a joint press conference held by both companies in Japan today, which we’ve embedded for you below. Toyota has paired with Idemitsu, whom it says has been performing research and development of solid-state batteries since 2001.
This particular battery collaboration focuses on sulfide solid electrolytes, which Toyota describes as a promising material in offering high capacity and output for future BEVs, thanks to their softness and adhesiveness to other materials.
The new partners state they have already established a task force consisting of dozens… yes dozens of people to help the venture reach mass battery production. That plan of attack will consist of a detailed three-phase plan:
- Phase 1
- Development of sulfide solid electrolytes and preparation for a large pilot facility
- Phase 2
- Mass production using a large pilot facility (rendering seen above)
- Idemitsu will promote sulfide solid electrolyte manufacturing and obtain mass production technology
- Toyota will promote development of both solid-state batteries and BEV development in which the batteries are incorporated, ensuring market launch of BEVs with the technology in 2027-28
- Mass production using a large pilot facility (rendering seen above)
- Phase 3
- Study of future full-scale mass production
Toyota states that Idemistu is currently increasing the capacity of its small pilot facility and is moving forward with construction of a large pilot facility that will eventually enable commercialization of the solid-state batteries in 2027.

The global critical minerals race is heating up — and rare earths stocks are skyrocketing

The emergence of critical minerals as a new arena of geopolitical competition has coincided with a dizzying rally in U.S.-listed rare earths mining stocks.
Despite paring gains in recent weeks, shares of Critical Metals have advanced 241% over the last three months, while NioCorp Developments, Energy Fuels and Idaho Strategic Resources have all surged well above 100% over the same period.
The eye-watering gains are even more remarkable year-to-date. Energy Fuels’ stock price has quadrupled through the first 10 months of the year, while NioCorp Developments’ shares have nearly quintupled.
Rare earths have come to the fore as a key bargaining chip in the ongoing geopolitical rivalry between the U.S. and China, the world’s two largest economies.
Tony Sage, CEO of Critical Metals, which has one of the world’s largest rare earths deposits in southern Greenland, described the rally of U.S.-listed rare earths miners as evidence of a major market boom.
“I talk of it like this, I mean, there have been four big booms. You had the gold boom in the 19th century, the oil boom in the 20th century, in the early 21st century you had the tech boom — and now you’ve got the rare earths boom,” Sage told CNBC by telephone.
“But the rare earths boom is the future. It will power all of the above.”
We are going from a philosophy of ‘fill the gap’ through imports to ‘mine the gap’ domestically or regionally.

Rare earths refer to 17 elements on the periodic table that have an atomic structure that gives them special magnetic properties. These materials are vital components to a vast array of modern technologies, from everyday electronics, such as smartphones, to electric vehicles and military equipment.
China, which has a near-monopoly on rare earths, recently threatened to expand its export controls on the elements to further leverage its dominance of the supply chain. However, following an in-person meeting in South Korea on Thursday between U.S. President Donald Trump and Chinese leader Xi Jinping, Beijing agreed to delay the Oct. 9 export controls by one year.
U.S.-listed rare earths stocks rallied on the news, although analysts remain skeptical about whether the apparent trade truce can offer long-term relief.

“As in all booms, there were a lot of oil companies that couldn’t find oil and there were a lot of gold companies that couldn’t find gold. And I’m sure there are going to be a lot of rare earths companies that won’t make it either — because when there’s a boom, there’s hype. And when there’s hype, there’s overexuberance in investing,” Critical Metals’ Sage said.
“It’s not a straight rise up. It’s a jagged line, but the trend is in the right direction if you’ve got the right project in the right place, and you’ve got the right partners,” he added.
‘A much bigger and longer supercycle’
Kevin Das, senior technical consultant at New Frontier Minerals, an Australian-based rare earths explorer, agreed with Sage’s description of a rare earths market boom, while acknowledging the likelihood of stock price pullbacks.
“People are saying we’re in an uptrend on what is a bigger supercycle and some of the evidence behind that is there has been low commodity prices for some time, there’s been underinvestment. And now, with the advent of AI … we’re going to see a much bigger and longer supercycle,” Das told CNBC by telephone.
Das drew parallels between the Biden administration’s support of clean energy projects, which coincided with a rally in lithium-related stocks, and the Trump administration’s backing of rare earths.

“In the last nine to 10 months that Trump has been in power, he’s talked about annexing Greenland, he’s talked about doing a deal with Ukraine for rare earths and then the real clincher was this equity deal with MP Materials,” Das said.
“So, I think the runway over the next two to three years is going to be very fruitful,” he added.
Not everyone is as bullish on the outlook for rare earths-related stocks, however.
Audun Martinsen, head of supply chain research at Rystad Energy, said the recent surge in equity prices reflected a mix of geopolitical tension, strategic policy support and speculative momentum.
“Rare earths have clearly moved to the center of global industrial strategy, vital for defense, EVs and clean energy, but this looks more like the early stages of a structural shift than a mature ‘fourth boom,'” Martinsen told CNBC by email.

“We are going from a philosophy of ‘fill the gap’ through imports to ‘mine the gap’ domestically or regionally,” he continued. “It will be a lengthy, expensive and rocky path forward as adequate, cost-effective resources and element diversity are complex to get full control over.”
Clean energy transition
Gernot Wagner, a climate economist at Columbia University, said there were two clear factors at work as global competition intensifies to secure the supply of critical minerals — one structural and the other political.
“The structural: Despite whatever political attempts there may be to stop or derail things, the clean-energy transition is happening — and it is accelerating — and yes, it depends on a number of critical minerals, whose prices are bound to jump,” Wagner told CNBC by email.
China, for instance, is the low-cost supplier of many of these minerals, Wagner said, noting that the Asian giant’s mineral dominance is by no means an accident.
“Beijing has invested heavily in green industrial policy for years, focusing on the full, integrated supply chain. That’s where politics enters,” Wagner said.
“Some attempts to onshore supply chains are eminently justified for national security and other reasons, and those attempts will increase prices and stocks of U.S. mining companies. Some of what we see, of course, is merely the current politics or erratic trade wars and the like,” he added.
For the last few weeks, we’ve been running a sidebar survey about how much Electrek readers think it would cost to add EV charging systems to their homes. After receiving over twenty-four hundred responses, here’s what you told us.
In our previous survey, we asked readers why they chose to install solar panels at home. In the recap, many of our commenters mentioned having their systems systems pull double duty — charging home backup batteries and topping off their electric cars. That got us thinking: as more and more first-time EV owners look into the many benefits of home charging, how much do they expect to pay for home charging?
Based on over 2,400 responses, this is what you told us.
What do you expect to pay for home charging?
The most positive surprise was that more than a third of Electrek readers who responded to the poll already had 240V outlets in their garage, so they expected to pay effectively $0 – their homes are EV ready now!
Of the remaining 64%, 44% were fairly evenly split between a relatively straightforward ~$500-1,000 wiring job with a few wiring or panel upgrades while only about 18% expected to spend over $1,000 due to having an older home, a detached garage, or for some other (apparently pricey and/or inconvenient) reason.
Navigating the questions
Just like you would for home solar, we’d recommend getting a quote from several installers before making a decision. One of our trusted partners, Qmerit, offers a quote-sourcing service called PowerHouse. The service scans pricing from thousands of completed electrification installations across North America to provide the best quotes that take regional variability into account and work with homeowners to “bundle” chargers, installation, and even batteries.
America has arrived at an inflection point in which all of the technical, policy and financial elements are in place to support a societal shift toward whole-home electrification. Now what’s needed is a comprehensive way to assemble these complex elements into a simple, financeable, home-energy retrofit that makes it easier to implement.
QMERIT FOUNDER TRACY PRICE
Qmerit says its new bundling program can flag the potential for federal, state, and local utility incentives like the ones we’ve covered from Illinois utility ComEd and others that can reduce or even eliminate the upfront costs of home installations for many.

Following a lawsuit brought against the California Air Resources Board (CARB) by major heavy truck manufacturers over California’s emissions requirements, CARB has struck back with fresh lawsuit of its own alleging that the manufacturers violated the terms of the 2023 Clean Truck Partnership agreement to sell cleaner vehicles.
Daimler Truck North America, International Motors, Paccar and Volvo Group North America sued the California Air Resources Board in federal court this past August, seeking to invalidate the Clean Truck Partnership emissions reduction deal they signed with the state in 2023 to move away from traditional trucks and toward zero-emission vehicles (ZEVs). The main point of the lawsuit was that, because the incoming Trump Administration rolled back Environmental Protection Agency (EPA) policies that had previously given individual states the right to set their own environmental and emissions laws, the truck makers shouldn’t have to honor the deals signed with individual states.
“Plaintiffs are caught in the crossfire: California demands that OEMs follow preempted laws; the United States maintains such laws are illegal and orders OEMs to disregard them,” the lawsuit reads. “Accordingly, Plaintiff OEMs file this lawsuit to clarify their legal obligations under federal and state law and to enjoin California from enforcing standards preempted by federal law.”
After several weeks of waiting for a response, we finally have one: CARB is suing the OEMs right back, claiming that the initial suit proves the signing manufacturers, “(have) unambiguously stated that they do not intend to comply.”
They want to sell Americans more diesel
In its lawsuit, CARB argues that monetary damages alone would not make the people of the State of California whole as far as damages are concerned, citing that the stated goal of the 2023 Clean Truck Partnership was, “to achieve emissions reductions that cannot be measured strictly in financial terms,” according to ACT-News.
The agency is asking the court to compel the truck companies to perform on their 2023 obligations or, failing that, to allow CARB to rescind the contract and recover its costs. A hearing on the truck makers’ request for a preliminary injunction was held Friday, with another court date set for November 21, when CARB will seek to dismiss the case brought forth by the truck brands. The outcome of these cases could shape how state and federal government agencies cooperation on emissions rules in the future.
You can read the full 22-page lawsuit, below, then let us know what you think of CARB’s response (and their chances of succeeding) in the comments.
