Group14 lands 3M from SK, Porsche, and others to make silicon anodes for EVs | TechCrunch

Group14 lands $463M from SK, Porsche, and others to make silicon anodes for EVs | TechCrunch

Battery materials startup Group14 announced Wednesday it has closed a $463 million funding round to expand its manufacturing footprint, a sign that investors remain confident in the future of electric vehicles.

The startup manufactures silicon anode materials, which significantly boost the storage capacity of lithium-ion batteries. Group14 currently operates three factories, two in the U.S. and one in South Korea.

Despite headlines about softening demand growth for electric vehicles, the global market for lithium-ion batteries remains strong. Over the next decade, it’s expected to grow more than 15% annually, quintupling in size, according to Precedence Research. And automakers and investors are still in pursuit of companies working on technology that will make EVs more efficient and affordable.

The round was led by battery manufacturer SK with participation from ATL, Lightrock, Microsoft, Porsche, and OMERS. Alongside the round, Group14 also announced it had “acquired full ownership” of a joint venture with SK in South Korea, which includes its BAM 3 factory. SK had owned 75% of the JV. When asked whether the value of the JV transaction was included in the Series D total, Group14 spokesperson Kristen Caron said the company was “not disclosing any additional details about the round.”

Silicon has long been targeted as a potential replacement for graphite, today’s go-to anode material, because it can hold up to 10 times more electrons. But with every charge and discharge, pure silicon anodes have a tendency to crumble as the material expands and contracts, something that graphite is more resistant to.

Startups like Group14 and its competitor Sila have accommodated silicon’s propensity to swell by creating structures that keep silicon in place without sacrificing the anode’s overall integrity. Group14’s material is a scaffold with internal voids that hold the silicon, giving it room to expand. 

The material itself can be blended with graphite or replace it entirely. Many companies still opt for the latter because of graphite’s inherent stability. But the more silicon used, the more energy a single cell can store. Group14 says its material can improve energy density by up to 50% and cut fast-charging times below 10 minutes.

Open-style wireless earbuds are all the rage these days, but not all the major brands are on board yet. Samsung, for example, still has its semi-open-ear Galaxy Buds 4, but nothing quite as open as the Bose Ultra Open Earbuds or Nothing’s Ear Open. I should say Samsung doesn’t have anything fully open yet.

According to a leak from SammyGuru, Samsung is working on a new pair of Galaxy Buds called the Galaxy Buds Able, and it looks like that unreleased pair might opt for an open-style clip design if illustrations found in recent One UI firmware are anything to go by.

In addition to the open-style design, SammyGuru is also reporting that the Galaxy Buds Able will use bone conduction, which is suited for delivering sound without needing to plug up your ears with silicone ear tips. Another benefit of bone conduction is that it’s not prone to sound leakage, which is often a downside of most pairs of open wireless earbuds. Bone conduction is also often used in more fitness-focused wireless earbuds, so there’s a chance the Galaxy Buds Able might lean into running and other exercise applications.

While clip-style open wireless earbuds aren’t novel—Sony, SoundPeats, and JBL all have their own pairs now—it’d be a departure for Samsung and a big indicator that open wireless earbuds are having a huge moment right now. If the leaks pan out, one of the things I’m most interested to see is whether Samsung endeavors to provide any kind of noise reduction. Though full-on active noise cancellation (ANC) isn’t possible without ear tips, brands like Shokz have managed to provide a surprisingly effective level of noise reduction that scratches a similar itch. Shokz’s OpenFit Pro, for example, are its only pair with noise reduction, but they do have a bulkier design. They’re not exactly clip-style; instead, they loop around the back of your ears with a sound module that nestles into the outer ear.

Since the Galaxy Buds Able aren’t official yet, there’s no word on price or release date, but there’s a chance they could end up being unveiled this summer at Samsung’s next Unpacked event.

I was delighted to see that the Acer Chromebook Plus 516 didn’t skimp on a crappy touchpad. That goes a long way toward improving the experiencing of actually using the laptop on a moment-by-moment basis. I wasn’t annoyed every time I had to click-and-drag or select a bit of text. This one’s biggest weakness is definitely the screen, which is true of just about every cheap Chromebook I’ve tested. The colors are ugly and desaturated, giving the whole thing a sickly green tint. It’s also not the sharpest in the world, as it’s stretching 1920 x 1200 pixels across a large, 16-inch screen. But in terms of usability and performance, the Acer Chromebook Plus 516 is a great value, combining an Intel Core i3 processor with 8 GB of RAM and a 128 GB of storage. For a Chromebook that’s often on sale for $350, it’s a steal.

While we’re here, let’s go even cheaper, shall we? Asus has two dirt-cheap Chromebooks that I tested last year that I was mildly impressed by. The Asus Chromebook CX14 and CX15. Notice in the name that these are not “Chromebook Plus” models, meaning they can be configured with less RAM and storage, and even use lower-powered processors. That’s exactly what you get on the cheaper configurations of the CX14 and CX15, which is how you sometimes get prices down to as low as $130. I definitely recommend the version with 8 GB of RAM, but regardless of which you choose, the both the CX14 and larger CX15 are mildly attractive laptops. You’d know that’s a big compliment if you’ve seen just how ugly Chromebooks of this price have been in the past.

With these, though, I appreciate the relatively thin bezels and chassis thickness, as well as the larger touchpad and comfortable keyboard. The CX15 even comes in a striking blue color. The touchpad isn’t great, nor is the display. Like the Acer Chromebook Plus 516, it suffers from poor color reproduction and only goes up to 250 nits of brightness. It only has a 720p webcam too, which makes video calls a bit rough. But that’s going to be true of nearly all the competition (and there isn’t much).

Of the two models, I definitely prefer the CX14 though, as it doesn’t have a numberpad and off-center touchpad, which I’ve always found to be awkward to use. Look—no one’s going to love using a computer that costs the less than $200, but if it’s what you can afford, the Asus Chromebook CX14 will at least get you by without too much frustration.

Whatever you do, don’t just head over to Amazon and buy whatever ancient Chromebook is selling for $100 for your kid. It’s worth the extra cash to get something with better battery life, a more modern look, and decent performance.

Other Good Chromebooks We’ve Tested

We’ve tested dozens and dozens of Chromebooks over the past years, having reviewed every major release across the spectrum of price. Unlike Macs and Windows laptops, Chromebooks tends to stick around a bit longer though, and aren’t refreshed as often. I stand by my picks above, but here are a few standouts from our testing that are still worth buying for the right person.
