Electric vehicle drivers and smartphone power users have been salivating over the prospect of silicon anode batteries, which promise to dramatically boost energy density and lower charging times.
Several companies have been working on silicon anodes over the last decade or so, and the tech has started creeping into consumer electronics. Wearable maker Whoop, for example, uses materials from Sila, while Group14‘s batteries can be found in a range of smartphones.
But the real prize is the EV market, which dwarfs consumer electronics by an order of magnitude, according to Benchmark Minerals. To break into this space, however, startups need to produce silicon anode material in far larger quantities than they have been so far.
To hit that scale, Group14 on Thursday said it had started production at its BAM-3 factory in South Korea. The facility is capable of producing up 2,000 metric tons of silicon battery materials annually, enough for 10 gigawatt-hours of energy storage, or about 100,000 long-range EVs.
“It’s a big deal for us, and I think it’s a big deal for the industry, too,” Rick Luebbe, co-founder and CEO of Group14, told TechCrunch.
The BAM-3 facility broke ground as a joint venture between Group14 and SK, the Korean battery manufacturer. SK owned 75% of the project, but sold its stake to Group14 last summer.
“SK has had their own challenges — financial and reprioritizing their battery and battery materials strategies all at the same time,” Luebbe said. “It did open up a great opportunity for us to acquire it from SK.”

The startup has been working with a number of companies, including Porsche’s battery division Cellforce Group, StoreDot, Molicel, and Sionic. Porsche has also invested in Group14 through its venture arm.
Most modern batteries use carbon as the anode material. It works well enough, but scientists have long known that silicon, which can store up to 10 times more lithium ions, would be better for energy storage if they could only solve some vexing durability problems: Pure silicon anodes are prone to swelling and crumbling in short order, making them unsuitable for repeated charging cycles over several years.
Group14’s answer is a hard carbon scaffold that holds minuscule silicon particles in place, preventing the anode from swelling or crumbling. That scaffold is shot through with nanoscale holes that allow the lithium ions and electrons to pass through. It also helps the anode charge quickly without breaking down.
Some of Group14’s customers, like Sionic, are using silicon anodes to boost energy density by up to 50%. Others, like Molicel, are focused on utilizing silicon’s fast-charging capabilities, including a design that can take a battery from flat to full in just 90 seconds.
That sort of application of silicon anodes could upend the EV market. Chinese EV maker BYD is already aiming to build that sort of capability: it last week revealed a new battery pack that can “flash” charge from 10% to 70% in five minutes. (Luebbe is convinced BYD is using silicon-carbon in its new battery. “It has to be,” he said.)
If charging networks can accommodate such an EV, range anxiety would be a thing of the past. Today, automakers have been striving to deliver 300 miles to 400 miles of range mostly to alleviate consumer concerns, but hitting those numbers requires large batteries that add bulk, heft, and cost. Flash charging that can deliver meaningful range in seconds could allow carmakers to slim down battery packs, saving cost and weight.
“I’ve got a Rivian with a 130 kilowatt-hour battery in it, which is ungodly expensive,” Luebbe said. But with flash charging, concepts like inductive charging at stoplights — which might seem outlandish today — start becoming more feasible, he said. “You’d never think about charging ever again.”

What every U.K. AI startup wants to know these days is, how can I get office space in King’s Cross?
The area is so hot that a VC firm allegedly recently won a deal by promising a founder office space in the neighborhood. “We stop at nothing to win deals [for] and to support” founders, “including helping them source office space when needed,” the firm told me when asked about the rumor, declining to confirm or deny any details.
The neighborhood’s popularity began back in 2016 when DeepMind — then newly acquired by Google — moved in. Soon after, a flood of AI startups followed, wanting to be around the Google DeepMind magic. Today, they hope to take advantage of the cluster of AI talent there.
This has transformed King’s Cross into one of the world’s top AI hubs, rivaled only by San Francisco and Beijing. Around London, it’s known by the sobriquet “Knowledge Quarter,” as it’s home to names like OpenAI, Meta, Isomorphic Labs, Cusp AI, Wayne, Recursive, and, a little farther down the road, Synthesia and Anthropic. The European Technology Network (ETN) just moved into a glossy new office nearby, while University College London sits around the corner.
Mixed in with the new developments are trendy food spots like Hoppers and BAO. Hop a train from King’s Cross, and founders can be in Cambridge in 45 minutes to source talent or can be in Paris in two hours to strike a deal.
Who would have guessed that a little more than 20 years ago, this was one of the seediest areas in London?
“In the ’80s, crack and heroin made the area a major narcotics market,” Hussein Kanji, an investor at Hoxton Ventures, said, recalling syringes in tree trunks and gangs patrolling the streets. “In 1982, the local church was occupied by the English Collective of Prostitutes for 12 straight days.” Then, in the early 2000s, a real estate developer had a dream and, well, “now it is the AI hotbed of the United Kingdom,” Kanji said. “What a change.” Around 18 months ago, his portfolio company BioCorteX moved from the neighborhood Holborn to the Jellicoe building in King’s Cross, hoping to be near the action. “Lots going on in London right now,” Nik Sharma, co-founder of BioCorteX, told me. “Lots of hyperscalers moving in.” That includes, reportedly, Jeff Bezos’ AI company Prometheus, which is also said to be in talks to move into the Jellicoe.
There are around 3,600 AI startups in London, which, together, have raised around .1 billion out of the .8 billion raised in the city since late July, according to Dealroom. Since the start of June, AI-related startups have leased more than 1 million square feet of office space in London, according to the real estate firm Knight Frank. With that, prime rents in King’s Cross have risen 18% over the past three years, Chris Dunn, a commercial insight associate at the firm, told me. That percentage represents only the largest leases encompassing at least 10,000 square feet, like the ones OpenAI and Prometheus are signing. The shorter deals go for even more, he said, and now the vacancy rate for conventional office space is just 0.9%. “Demand has outstripped supply,” he continued.
Today, one of the big topics of the area is sovereignty. It was a wake-up call for many when Anthropic shut off access to Mythos and Fable this summer, leaving some in the ecosystem to conclude: “We’d better look after ourselves,” Saul Klein, co-founder of the VC firm Phoenix Court, told me.
Phoenix Court is located in the King’s Cross area and has three portfolio companies in the vicinity, including Olix (which just announced a .3 billion valuation), Early Health and CoMind. Robin Klein, co-founder of the firm, said the shutdown of Fable and Mythos access was a “small but sharp reminder that Europe can’t simply rent its AI capabilities and capacity; it needs to build and hold some of its own.” King’s Cross, he said, is where much of this building is actually happening.
“The bigger question,” he continued, “is whether the U.K. builds the infrastructure, compute, energy, capital, to make this self-reliance durable, rather than just hosting outposts of U.S. labs.”

Top founders want to stay
Simon Kohl, founder of Latent Labs, has offices in King’s Cross and San Francisco. The London office, at the moment, is growing faster, and he’s more bullish than ever on the ecosystem, he said. “The mood right now feels less like London trying to catch up and more like London becoming one of the default places to start a serious AI company,” he said. Look around and you are likely to see Wayve testing its autonomous cars. Founded in 2017 by co-founder Alex Kendall, the unicorn is one of London’s biggest success stories.
“Ten years ago, building a frontier AI company from London felt like an unusual choice,” Kendall told me. “Now it feels like an obvious one.” Wayve moved into King’s Cross in 2018 looking for a space that could double as a garage — “a rare combination in Central London,” Kendall said. He has watched the ecosystem mature around him — and it’s now evident that a startup can stay in London, raise serious capital, hire world-class AI talent, and remain globally competitive, he said. Down the street from Anthropic’s new 158,000-square-foot office is the AI agent builder Sierra and the AI video platform Synthesia.
Laura Gonzalez Florez, Synthesia’s chief of staff and head of people, says the company moved into its glossy new office building a year ago to accommodate its growing team. They were drawn to the area for the same reason as everyone else: “It’s very close to the airport … very close to where a lot of investors are,” she said.

Around two-thirds of Synthesia’s engineers are remote, Gonzalez Florez said, letting the company tap into an affordable, international, and diverse talent pool and helping it scale faster. “From London, we can hire and work, without any problem, people from anywhere, from Slovenia to Portugal,” she said.
Unsurprisingly, London’s AI boom is also causing a talent war.U.K. AI job postings have skyrocketed in the past few years, per data from PwC. When Anthropic announced it moved into town earlier this year, it listed, for example, a salary range of £260,000 to £630,000 for a machine learning research engineer when the average salary in London for the same role is around £102,000. Some founders in the U.K., like those in Silicon Valley, are being forced to raise more and bigger rounds to keep up.
“The real test is whether more globally significant AI companies are founded, funded, and scaled from the U.K., while continuing to attract the world’s best talent to build them here,” Zain Ali, founder of the King’s Cross-based AI legal firm Centuro, told me. “If that continues to happen, King’s Cross won’t just be an AI hub. It’ll become one of the U.K.’s most important strategic assets.”
