Silicon anodes appear to be leading the way in the race to commercialize next-generation battery technologies for electric vehicles.

The buzz around silicon-based anodes, which promise improved power and faster charging capabilities for EVs, has been growing in recent months — just as the hype around solid-state batteries seems to have fizzled.

It comes as increasing EV sales continue to drive up global battery demand, prompting auto giants to team up with major cell manufacturers on the road to full electrification.

While some OEMs (original equipment manufacturers) have inked deals with solid-state battery developers, carmakers such as Mercedes, Porsche and GM have all bet big on silicon anodes to deliver transformative change in the science behind EVs.

A recent report from consultancy IDTechEx described the promise of advanced silicon anode materials as “immense” for improving critical areas of battery performance, noting that this potential hadn’t gone unnoticed by carmakers and key players in the battery industry.

It warned, however, that challenges such as cycle life, shelf life and — perhaps most importantly — cost, need to be addressed for widespread adoption.

Venkat Srinivasan, director of the Collaborative Center for Energy Storage Science at the U.S. government’s Argonne National Laboratory in Chicago, said silicon anodes appear to have the edge over solid-state batteries.

“If there’s a horse race, silicon does seem to be ahead at least at this moment, but we haven’t commercialized either one of them,” Srinivasan told CNBC via videoconference.

How silicon could enable cheaper EVs, electric flight and more powerful batteries

Srinivasan said five years ago silicon-anode batteries had a calendar life of roughly one year, but recent data appears to show a dramatic improvement in the durability of these materials, with some tests now projecting a three to four-year calendar life.

Unlike the cycle life of a battery, which counts the number of times it can be charged and discharged, the calendar life measures degradation over time. Typically, the calendar life of a battery refers to the period in which it can function at over 80% of its initial capacity, regardless of its usage.

Srinivasan said solid-state batteries, long billed as the “holy grail” of sustainable driving, still have a long way to go before they can match the recent progress made by silicon anodes.

“That transition still has to be made in solid-state with their metal batteries and that’s why I think you’re hearing from people that, hey, it looks like that promise hasn’t panned out,” Srinivasan said.

“That doesn’t mean we won’t get there. It may happen in a few years. It just means that it feels like today silicon is in a different part of the technology readiness level.”

Silicon anodes vs. solid-state batteries

Analysts say silicon anodes theoretically offer 10 times the energy density as graphite, which are commonly used in battery anodes today. Yet, these same materials typically suffer from rapid degradation when lots of silicon is used.

“Silicon anodes and solid-state batteries are two emerging technology trends in the EV battery market aimed at pushing the boundaries of high-performance battery cells,” Rory McNulty, senior research analyst at Benchmark Mineral Intelligence, told CNBC via email.

It has typically been the case that better battery performance comes at the cost of longevity or safety, McNulty said. Silicon anodes, for example, are known to swell significantly during charging, which reduces the battery’s longevity.

By comparison, McNulty said solid-state batteries were claimed to greatly improve the stability of the electrolyte to high performance electrode materials, combating the challenges of using high energy density materials such as silicon and lithium.

As the name suggests, solid-state batteries contain a solid electrolyte, made from materials such as ceramics. That makes them different from conventional lithium-ion batteries, which contain liquid electrolyte.

Especially in the West, advances in the area of silicon anodes [are] seen as strategic opportunity to catch up with China.

Japan’s Toyota and Nissan have both said they are aiming to bring solid-state batteries into mass production over the coming years, while China’s SAIC Motor Corp reportedly said in early September that its MG brand would equip cars with solid-state batteries within the next 12 months.

Nonetheless, analysts remain skeptical about when solid-state batteries will actually make it to market.

A strategic opportunity?

“Silicon based anodes promise to be the next-generation technology in the anode field, providing a solution for faster charging,” Georgi Georgiev, battery raw materials analyst at consultancy Fastmarkets, told CNBC via email.

Georgiev said several industry players have been looking into the potential of silicon anodes, from well-established anode suppliers in China and South Korea to new players like Taiwan’s ProLogium and U.S. manufacturers Group14 and Sila Nanotechnologies.

“Especially in the West, advances in the area of silicon anodes [are] seen as strategic opportunity to catch up with China, which dominates the graphite-based anode supply chains with Chinese anode producers holding 98% of the global anode market for batteries,” Georgiev said.

“However, there are significant technical challenges going to 100% silicon anode such as silicon expansion affecting the longevity of the batteries and currently there are several routes to produce silicon anodes,” he added.

Taiwanese battery maker ProLogium debuted the world’s first fully silicon anode battery at the Paris Motor Show last month, saying it’s new fast-charging battery system not only surpassed traditional lithium-ion batteries in performance and charging efficiency but also “critical industry challenges.”

ProLogium, citing test data, said it’s 100% silicon anode battery could charge from 5% to 60% in just 5 minutes, and reach 80% in 8.5 minutes. It described the advancement as an “unmatched achievement in the competitive EV market,” which will help to reduce charging times and extend the range of EVs.

Fastmarkets’ Georgiev said a big question mark over the commercialization of silicon anodes is the cost of production and whether any of the major silicon-anode producers “could produce material at scale with a consistent quality and at a competitive price — [a] major requirements of OEMs.”

“At this stage silicon anodes are used more as an additive to graphite-based anodes and in the years to come we expect to see increase of silicon share in anode, but in combination with graphite, while 100% silicon anodes will take longer time to enter the mass market,” he added.

Out of control Mustang Mach-E in viral video isn't real, driver arrested for DUI

That viral Tik Tok video showing a “self driving” Ford Mustang Mach-E scraping its way down the highway with a helpless passenger behind the steering wheel praying for his life? California Highway Patrol says the car wasn’t driving itself during the viral highway crash and arrested the driver on suspicion of driving under the influence.

If you have’t seen the video, posted by TikToker Marty Byrde, it shows a self-driving Ford Mustang Mach-E driving down the road, grinding itself against the highway’s concrete Jersey barriers, with the driver behind the wheel, seemingly helpless and afraid and trapped inside an out-of-control vehicle, apparently praying for his life.

There, in a single video, was everyone’s worst fear in an age of electric steering, brake-by-wire, and self-driving cars: a car that loses its mind, killing you and everyone you love and probably a busload of orphans for good measure. (!)

But, thankfully, that doesn’t seem to be what actually happened. At least, not according to the California Highway Patrol (CHP) in Redwood City.

In case it vanishes, the CHP press release does a good job of explaining the situation as it stands, while emphasizing that any short-form video content is going to lack potentially needed context before the public begins to panic about a Maximum Overdrive sort of scenario.

The preliminary investigation indicates the driver of a green Ford Mustang Mach E, crashed into a red Mitsubishi Mirage then collided with the right shoulder wall near the Holly Street overcrossing. Through our investigation, we determined the vehicle was not operating in autonomous mode and CHP officers arrested the driver on suspicion of driving under the influence, resulting in injuries to another.

While we understand public interest in such incidents, video clips may not capture the complete context or investigative process. The CHP conducts each investigation thoroughly, professionally, and in accordance with the law. We thank the community for its concern and remind motorist to report dangerous driving by calling 9-1-1.

CALIFORNIA HIGHWAY PATROL – REDWOOD

The video was especially surprising given Ford’s BlueCruise excellent track record. The system is good enough, in fact, to have been named the top active driver assistance system (ADAS) by Consumer Reports, surpassing rivals such as GM’s Super Cruise and Tesla’s Autopilot in a comparison test of similar OEM ADAS systems.

The original Tik Toker who recorded the now viral video (I hate that phrase, too, but millions of people have seen it by now) reported that no one seemed hurt in the ensuing accident. Coupled with CHP’s confirmation that the Mach-E wasn’t driving itself during the accident, I’d say that walking out of a hands-free, highway speed crash is as good an endorsement as any … but in case you need another one, this one went 250,000 miles and still had 92% of its battery life left.

Ford is currently offering 0% interest financing for up to 72 months for well-qualified buyers, as well as $1,000 in retail bonus cash in some markets.

No, Trump’s Big Beautiful Bill doesn’t mean it’s too late to benefit from home solar

No, Trump's Big Beautiful Bill doesn't mean it's too late to benefit from home solar

The Trump Administration’s “Big Beautiful Bill” (BBB) is doing a lot of damage to America’s health, economy, and global standing – but one thing it certainly has not done is make it “too late” for US homeowners to benefit from a rooftop solar system.

Companies like Tesla and Rivian are reeling from the double-whammy of Trump’s BBB ending the $7,500 Federal EV tax credit early and killing the market for carbon tax credits, which provides EV car brands with hundreds of millions of dollars, almost overnight. Still another part of the bill that’s getting a lot of publicity is the death of the 30% tax credit for home solar systems at the end of 2025, which has led many Americans who have been “on the fence” about adding a solar or solar + storage solution to their home to believe they waited too long to go solar.

The good news? It’s not too late. Homeowners who get solar installed and operational by December 31st can still claim a full 30% federal tax credit for 2025, and any unused portion of that credit rolls over to the next tax year.

The better news? Even without the solar tax credit, adding a home solar system with battery backup storage can still deliver a positive ROI.

Solar benefits go beyond tax credits

The most obvious benefit of home solar plus battery storage is that you can produce your own energy (or, if you’ve been following along for a while, electric fuel) for less than it would cost you to buy that energy from your local utility. That’s been true for a while, but it’s about to become even more true.

Outlets like The Washington Post and The Guardian are predicting that household energy bills in Republican-leaning states could rise by more than $600 next year, based on their analyses of the BBB. One study, by energy and climate think tank Energy Innovation, showed energy prices rising by much as 18% by 2035 as a result of Trump’s policies.

Energy Innovation’s analysis skews left, and tends to focus on “left of zero” outcomes. Still, when the corporatist rags start quoting bad numbers and bear markets, you should probably pay attention. Some of the key takeaways of the EI study include:

  • Power generation capacity will fall 340 gigawatts by 2035, raising costs to meet growing demand and damaging industrial competitiveness
  • Wholesale electricity prices will increase 25 percent by 2030 and 74 percent by 2035; electricity rates paid by consumers will increase between 9-18 percent by 2035
  • Household energy costs will increase $170 annually by 2035
  • America loses $980 billion in cumulative GDP through the budget reconciliation window
  • Florida, Texas, Kentucky, and both North and South Carolina stand to be hit the hardest by rising energy costs over the next ten years

Beyond insulating your household budget from rising energy costs, a home solar system can help to insulate your home, too – which means you’ll need less of that lower cost electricity you’re generating to keep it cool in the summer and warm in the winter.

That’s not just me saying that. A study by the Jacobs School of Engineering at UC San Diego study found that during the day, ceilings under tilted solar panels were about 5°F cooler than exposed ceilings, thanks to the panels acting as a shade and creating an air gap that helps dissipate heat. In cool weather, the panels helped homes retain heat, leading to a dual benefit across multiple seasons.

“There are more efficient ways to passively cool buildings, such as reflective roof membranes,” explains Jan Kleissl, a professor of environmental engineering at UC San Diego. “But, if you are considering installing solar photovoltaic, depending on your roof thermal properties, you can expect a large reduction in the amount of energy you use to cool your residence or business.”

Keeping your own personal costs at bay while putting clean, excess energy that’s not stored in your home batteries back into the grid is a win-win that not only reduces your own energy bills but also puts downward pressure on wholesale electricity prices.

What’s more, because the rising costs of energy prices are outpacing interest rates, it might even make sense to finance a solar package – but definitely don’t take my word for that. Talk to a certified financial planner or someone with a fiduciary interest in your money to work the numbers before you start signing stuff.

Not enough: Corvette concept falls 1,000 hp short of Chinese hypercar hype [video]

Not enough: Corvette concept falls 1,000 hp short of Chinese hypercar hype [video]

The Corvette CX making its debut at this weekend’s The Quail, a Motorsports Gathering, generates more than 2,000 combined hp from its four, individually controlled and torque-vectoring electric motors. It’s staggering power, draped in beautiful bodywork, at a point in time when Corvette is rapidly climbing through the supercar ranks. There’s only one problem with this latest rendition of America’s motorsports icon: China’s has 1,000 more hp.

The specs for the Yangwang U9 Track Edition that leaked last week in BYD filings with the Ministry of Industry and Information Technology (MIIT) read like something out a middle schooler’s journal. 3,000 hp. 0-60 in one second. An electric motor for each wheel. A top speed approaching 300 mph. If it’s real (and there is absolutely zero reason to believe that it isn’t), the BYD will be the performance car benchmark against which all others are measured, like the Ferrari F40 of the 1980s, McLaren F1 of the 1990s, or Bugattis of the twenty-first century.

And that 3,000 hp BYD? That’s a production car, if limited. Meanwhile, the latest no production intent, pie-in-the-sky, no-holds-barred, you can just say shit and no one will ever question it electric hypercar concept from GM falls more than 1,000 hp short, at “just” 2,000 hp.

But don’t count the Corvette out.

More grease, bigger hammer

Whatever you may think of poster-era supercars like the Lamborghini Diablo, Porsche Carerra GT, or Pagani Huayra – or even modern electric hypercars like the Tesla Model S Plaid and Xiaomi SU7 – the one thing they all have in common is that they are all objectively slower than the 255 mph Callaway Corvette Sledgehammer from 1988, above.

I won’t go into the specs of that car (this isn’t that kind of car blog), but the point is that while the Corvette is often overlooked, there is a reason GM’s top-shelf sporty car carries that “King of the Hill” nickname – and the new Corvette CX concept is similarly, undoubtedly, more than just a list of specs in a magazine.

And those specs are seriously impressive. The new Corvette CX concept packs four independent electric motors putting out a combined 2,000 hp and some ungoldy amount of Earth-moving torque under advanced software controls that enable four-wheel torque vectoring for maximum grip and cornering performance, as well as precise steering control under even the heaviest of braking.

Power to those motors comes from the Corvette CX’ 90 kWh lithium-ion battery that’s centrally mounted low in the chassis, giving the car a low center of gravity and, crucially, ideal 50/50 front-rear weight distribution.

Plus: it’s gorgeous


The Corvette team says the CX concept draws from more more than seventy (!) years of Corvette heritage while being a forward looking concept, not a retro piece. Stylistically, the concept seems more visually mature and subdued than its in-production C8 cousin, and seems to promise a return to the C3-5 eras’ cleaner, less busy aesthetics.

Phil Zak, executive design director for Chevrolet, is very rightly proud of the CX’ design. “While the shape of a Corvette has always been expressive and forward-looking, each crease and line has its roots in the generations that came before it. It is aspirational, it is cultural, it is the reason people want to come and work at Chevrolet,” says, Zak. “The CX … demonstrate(s) our design teams stepping away from the constraints of production vehicles and unleashing their creativity. Through this exercise, we’ve added to Corvette and defined the design direction for Corvette moving forward.”

The rest of the official GM press release copy highlights the aviation-inspired canopy, jet-age interior, and an underbody fan system not entirely unlike the system leaked in Tesla patent filings earlier this week. You can see that here:

Aggressively futuristic, yet unquestionably a Corvette, the CX concept shows what an uncompromised future sports car can be. The athletic exterior design, highlighted by the fighter-jet-inspired cockpit canopy, isn’t just about looking powerful – it was shaped in collaboration with the GM Motorsports Aero Group. Every angle was designed with ultimate performance in mind.

On the inside, every aspect of the CX concept was designed to provide an unmatched driving experience. The forward-opening fighter-jet-style canopy automatically raises as you approach. Driver and passenger settle into seating finished in Inferno Red ballistic textile, bolstered to help hold occupants in place during high-g cornering maneuvers. Premium silicone leather, milled aluminum, and low-gloss forged carbon fiber accents give an elevated feel to the driver-focused cabin.

The digital windscreen transforms the windshield into an immersive surround display with real-time performance data. Every major control is elegantly integrated into the steering wheel, keeping the driver’s focus on the road ahead.

The innovations continue underneath the skin with the Vacuum Fan System. Built-in fans draw air through the open-channel bodywork, generating massive downforce and adjusting the airflow over the rear diffuser to refine aerodynamic balance in real-time. The front diffuser and rear wing are both active, adjusting automatically in response to the driver’s inputs to generate maximum grip. The integrated understructure of the CX concept is visible through the aero channels in the bodywork, and the suspension A-arms are wing-shaped to enhance airflow and reduce front-end lift.

CHEVROLET

All in all, the new Corvette CX concept is an impressive piece of engineering and rolling art. It’s also a statement from GM that, while the Corvette may very well be going all-electric in its next iteration, it won’t be going any slower. In fact, the first electric Corvette might even be the best one ever – but don’t say that one too loud (you’ll upset the New Balance crowd).

That said, as a pure concept that almost no one will ever drive and which might never get publicly strapped on to a dyno, it is absolutely baffling that Chevy wouldn’t have just claimed 3,000 hp. Even if it was just to match BYD’s claims and continue to build on a century of hype for American exceptionalism, you know?

That’s my take, anyway – what’s yours? Watch the Corvette CX Concept hype video from Chevrolet, below, then let us know what you think of the latest GM concept in the comments.
