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.
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.
A fully electric Isuzu pickup truck? That’s right. The D-MAX EV is Isuzu’s first electric pickup, and it will be rolling in the next few months. After kicking off mass production, Isuzu said the new EV pickup will “match the performance of existing diesel models,” boasting high towing capacity and payload.
Isuzu’s first electric pickup is launching in 2025
Isuzu announced on Tuesday that the D-MAX EV has officially entered mass production. The company has started building left-hand drive models, which will be shipped to Europe in the third quarter of 2025.
By the end of the year, production of right-hand drive models will begin for the UK, with sales expected to start in 2026.
The electric pickup is nearly identical to Isuzu’s popular gas-powered D-MAX, but swaps the diesel powertrain for a pair of electric motors. The D-MAX EV features new e-Axles, one on the front and the other at the rear, for a full-time 4WD system.

The dual-motor powertrain enables it to match the performance of existing diesel models, with a combined 188 hp (140 kW) and a maximum torque of 240 lb-ft (325 Nm).
It can also tow over 7,700 lbs (3,500 kg) with a maximum payload of over 2,200 lbs (1,010 kg). That’s about the same as the D-MAX diesel, which has a 3,500 kg towing capacity and a payload capacity of up to 1,200 kg.
Powered by a 66.9 kWh battery, Isuzu’s first electric pickup boasts a driving range of up to 263 km (162 miles) on the WLTP. In the city, it can have a driving range of up to 224 miles (361 km).

For the first time in five years, a Tesla insider required to report Tesla stock transactions bought stocks rather than selling them.
But the transaction is so small that it makes the whole situation hilarious.
Insiders in public companies are top executives and board members who are required to report to the SEC any transaction related to the company’s stock.
For Tesla, it has become a running joke that insiders only sell, never buy the stock.

This has been true without exception for years.
We don’t know as much about executives as Tesla has a very short top executive bench who are required to file transactions. However, when it comes to its board members, they have been selling at an impressive rate.
However, we now have confirmation that a Tesla board member is buying, rather than selling.
Joe Gebbia, the Airbnb co-founder who joined Tesla’s board in 2022, confirmed that he bought 4,000 shares in Tesla last week worth about $1 million:
Electrek’s Take
Gebbia is estimated to be worth over $7 billion. Therefore, his purchase of $1 million worth of Tesla stock would be equivalent to my buying a fractional share in Tesla.
Furthermore, the disclosure confirmed that despite being on the board for the last 3 years, Gebbia owned only 111 shares in Tesla before the transaction.
That’s quite the show of confidence in Tesla.
Thie whole situation with the board is disappointing. Tesla’s core business is melting. The company reported its worst quarter in years last week, and the stock surged 20%.
None of it makes any sense.
The board is sitting on its hands while the most powerful force accelerating the advent of electric transport is being destroyed in favor of nonsensical predictions about the potential of solving self-driving and humanoid robots.

Venmo, long a centerpiece of PayPal‘s growth story but often criticized for its lack of monetization, is becoming a bigger contributor to the business.
PayPal said Tuesday in its first-quarter earnings release that revenue at Venmo increased 20% year-over-year in the first quarter, though the company didn’t provide a dollar figure. PayPal acquired Venmo in 2013 through the acquisition of parent company Braintree.
While it’s long been a popular consumer service for sending money to friends, Venmo’s ability to drive meaningful revenue has been a major question mark for investors, especially as competition from rivals like Zelle and Square Cash has intensified.
Venmo’s total payment volume rose 10% from a year earlier, but revenue grew twice as fast, reflecting the business opportunity. Venmo only gets revenue from specific products like Pay with Venmo at online checkout, Venmo debit cards, and instant transfers, but not from peer-to-peer payments.

Ahead of the earnings report, Jefferies analysts noted that Venmo revenue growth appeared to be “accelerating sharply” and flagged its rising contribution to branded checkout as a key area to watch. Compass Point analysts similarly said that while competition from Zelle and Square Cash remains fierce, Venmo’s traction with debit cards and online checkout could “open up new monetization avenues” if adoption trends continue.
The company added nearly 2 million first-time PayPal and Venmo debit card users during the quarter, and total debit card payment volume across PayPal and Venmo climbed more than 60%. Meanwhile, Pay with Venmo transaction volume surged 50% year over year, and Venmo debit card monthly active users grew about 40%.
PayPal reported better-than-expected earnings for the quarter but missed on revenue. The company reaffirmed its full-year guidance, citing macroeconomic uncertainty.
