3D porous structure promises safer, longer-lasting lithium-metal batteries for electric vehicles

According to the International Council on Clean Transportation, as of early 2024, there are approximately 40 million electric vehicles (EVs) in operation worldwide. Among them, verified battery-related fires in light-duty EVs number just over 500 between 2010 and mid-2023, corresponding to a fire risk of roughly 1 in 100,000 vehicles.

While this rate is substantially lower than that for internal-combustion-engine vehicles, EV battery fires remain a major concern because once thermal runaway occurs and a fire ignites, they can be extremely difficult to extinguish and may reignite.

A research team from POSTECH (Professor Soojin Park, Dr. Dong-Yeob Han, Gayoung Lee) and Chung-Ang University (Professor Janghyuk Moon, Seongsoo Park) has developed a novel three-dimensional porous structure that significantly improves both the lifespan and safety of -metal batteries (LMBs). Their work is published in Advanced Materials.

Lithium metal batteries promise much higher energy density than today’s lithium-ion batteries and could dramatically extend EV driving range. However, the main barrier to commercialization has been the tendency of lithium metal to deposit unevenly during charging and discharging, forming needle-like “dendrites” that can pierce separators and cause internal short-circuits or even explosions.

The team’s solution is simple yet effective: they engineered a porous host structure with straight, low-tortuosity channels and a built-in lithiophilicity gradient enabling uniform lithium deposition from the bottom up. Think of a parking garage: if the entrance is narrow and lanes are winding, cars tend to bunch at the entrance. But if you build wide straight ramps and make lower floors more spacious, vehicles naturally fill the lower floors first. Their electrode design applies this principle to lithium ions in the battery.

Using a nonsolvent-induced phase separation (NIPS) process, they created the porous host by mixing a polymer matrix with carbon nanotubes (CNTs) and silver (Ag) nanoparticles to enhance electrical conductivity, while introducing an Ag layer on a copper substrate to induce lithium nucleation at the base. As a result, bottom-up lithium deposition with fully suppressed dendrite growth and greatly improved structural stability.

In tests, batteries built with this host achieved an energy density of 398.1 Wh/kg and 1,516.8 Wh/L, far exceeding typical lithium-ion batteries (~250 Wh/kg, ~650 Wh/L). Even under commercial-level conditions with low electrolyte content, a thin lithium anode, and real-world cathodes such as NCM811 and LFP, they demonstrated outstanding stability without short circuits or capacity collapse. If applied to EVs, this improvement could potentially extend driving range by roughly 60–70% (for example, a vehicle that currently travels ~400 km per charge might reach ~650–700 km).

Professor Park stated, “This research presents a new way to simultaneously control ion transport pathways and lithium growth behavior inside electrodes, without relying on complex manufacturing processes. Designing both the ‘path’ and the ‘direction’ of lithium movement will be a turning point in advancing toward the commercialization of safe, high-energy .”

Professor Moon added, “Our process allows simultaneous control of microstructure and chemical gradients through a simple fabrication route, making it highly scalable for industrial production.”

Disney content has gone dark on YouTube TV. Here’s what customers should know

Disney content has gone dark on YouTube TV. Here’s what customers should know

Disney content has gone dark on YouTube TV, leaving subscribers of the Google-owned live streaming platform without access to major networks like ESPN and ABC.

That’s because the companies have failed to reach a new licensing deal to keep Disney channels on YouTube TV. Depending on how long it lasts, the dispute could particularly impact coverage of U.S. college football matchups over the weekend—as well as NBA and NFL games—on top of other news and entertainment disruptions that have already arrived.

In the meantime, YouTube TV subscribers who want to watch Disney channels could have little choice other than turning to traditional broadcasting or the company’s own platforms—which come with their own price tags.

Here’s what we know.

Why is Disney content not on YouTube TV today?

Disney content was pulled from YouTube TV after a carriage agreement expired on Thursday. The two sides have been unable to reach a new deal to continue licensing Disney channels on the platform—resulting in the current blackout.

YouTube TV says that Disney is proposing terms that would be too costly, resulting in higher prices and fewer choices for its subscribers. Google’s streamer has accused Disney of following through on “the threat of a blackout on YouTube TV as a negotiating tactic”—and claims that the move also benefits Disney’s own streaming products like Hulu + Live TV and Fubo.

Meanwhile, Disney says that YouTube TV has refused to pay fair rates of its channels—and is therefore choosing “to deny their subscribers the content they value most.” The California entertainment giant also accused Google of “using its market dominance to eliminate competition and undercut the industry-standard terms we’ve successfully negotiated with every other distributor.”

In a Friday note to employees, Disney Entertainment Co-Chairs Dana Walden and Alan Bergman and ESPN Chairman Jimmy Pitaro added that YouTube TV pulled Disney content Thursday night “prior to the midnight expiration of our deal”—and noted the platform also deleted subscribers’ previously-recorded programming. The Associated Press reached out to Google for further comment.

What channels are impacted?

ESPN and ABC are among the biggest networks that YouTube TV subscribers can no longer access amid the dispute.

And beyond those top sports and news offerings, other Disney-owned content that is now dark on the platform include channels specific to U.S. college athletic regions, like the Atlantic Coast Conference and the Southeastern Conference. NatGeo and FX are also impacted.

Here’s a recap of the full list outlined by YouTube TV:

1. ESPN, ESPN2, ESPNU, ESPNews and ESPN Deportes (Spanish Plan)

2. ABC and ABC News Live

3. Nat Geo, Nat Geo Wild and Nat Geo Mundo (Spanish Plan)

4. Disney Channel, Disney Junior and Disney XD

5. FX, FXX and FXM

6. SEC Network and ACC Network

7. Freeform

8. Localish

9. Baby TV Español (Spanish Plan)

Google says that streamer adds-ons like 4K Plus and Spanish Plus are also affected.

Where else can I watch ESPN and ABC?

Consumers can continue to watch Disney’s sports programming on the company’s own ESPN offerings—but it will come with an additional cost. For streaming, the network launched its own platform earlier this year under the same ESPN name, starting at $29.99 a month.

Other Disney content can be found on platforms like Hulu, Disney+ and Fubo. Again, those come with their own price tags. Disney also allows people to bundle ESPN along with Hulu and Disney+ for $35.99 a month—or $29.99 a month for the first year.

Disney also directed customers to a website called KeepMyNetworks.com to explore other options, which includes more traditional broadcast services.

But if you’re a YouTube TV subscriber and don’t have these streaming subscriptions or broadcast offerings, you might be left without access to this Disney content as long as the impasse lasts. YouTube TV said it would give subscribers a $20 credit if Disney content unavailable “for an extended period of time.”

YouTube TV’s base subscription plan costs $82.99 per month. Beyond Disney content, the platform currently offers live TV from networks like NBC, CBS, Fox, BBC, PBS, Hallmark, Food Network and more.

How long could the dispute last?

YouTube TV and Disney have acknowledged that the disruption is frustrating—and both maintain that they’re still committed to finding a resolution. But only time will tell.

The current blackout marks the latest in growing list of licensing disputes that impact consumers’ access to content.

From to awards shows, live programming that was once reserved for broadcast has increasingly made its way into the streaming world over the years—as more and more consumers ditch traditional cable or satellite TV subscriptions for content they can get online. But renewing carriage agreements can also mean tense contract negotiations, particularly amid growing competition in the space.

YouTube TV and Disney have been down this road before. In 2021, YouTube TV subscribers also briefly lost access to all Disney content on the platform after a similar contract breakdown between the two companies. That outage lasted less than two days, with the companies eventually reaching an agreement.

Some past impasses have been shorter and limited to a matter of hours—or found a way to temporarily ward of disruptions at the last minute. In August, for example, YouTube TV reached a “short-term extension” in its contract dispute with Fox, and the two later reached a new licensing deal.

Meta Claims Downloaded Porn at Center of AI Lawsuit Was for ‘Personal Use’

Meta Claims Downloaded Porn at Center of AI Lawsuit Was for ‘Personal Use’


Further, that alleged activity can’t even reliably be linked to any Meta employee, Meta claims.

Strike 3 “does not identify any of the individuals who supposedly used these Meta IP addresses, allege that any were employed by Meta or had any role in AI training at Meta, or specify whether (and which) content allegedly downloaded was used to train any particular Meta model,” Meta wrote.

Meanwhile, “tens of thousands of employees,” as well as “innumerable contractors, visitors, and third parties access the internet at Meta every day,” Meta argued. So while it’s “possible one or more Meta employees” downloaded Strike 3’s content over the past seven years, “it is just as possible” that a “guest, or freeloader,” or “contractor, or vendor, or repair person—or any combination of such persons—was responsible for that activity,” Meta claims.

Other alleged activity included a claim that a Meta contractor was directed to download adult content at his father’s house, but those downloads, too, “are plainly indicative of personal consumption,” Meta argued. That contractor worked as an “automation engineer,” Meta noted, with no apparent basis provided for why he would be expected to source AI training data in that role. “No facts plausibly” tie “Meta to those downloads,” Meta claims.

“The fact that the torrenting allegedly stopped when his contract with Meta ended says nothing about whether the alleged torrenting was performed with Meta’s knowledge or at its direction,” Meta wrote.

Meta Slams AI Training Theory as “Nonsensical”

Possibly most baffling to Meta in Strike 3’s complaint, however, is the claim about the “stealth network” of hidden IPs. This presents “yet another conundrum” that Strike 3 “fails to address,” Meta claims, writing, “why would Meta seek to ‘conceal’ certain alleged downloads of Plaintiffs’ and third-party content, but use easily traceable Meta corporate IP addresses for many hundreds of others?”

“The obvious answer is that it would not do so,” Meta claims, slamming Strike 3’s “entire AI training theory” as “nonsensical and unsupported.”

Christian Influencers Are Throwing Their Hatch Clocks in the Trash

Christian Influencers Are Throwing Their Hatch Clocks in the Trash


Treasure to Trash and Back Again

According to Erin Merani, Hatch’s vice president of marketing, this series of events was not, in fact, a planned marketing stunt, and Hatch is still figuring out the ramifications of the demon discourse. While Merani is glad the ads and programming “caught people’s attention,” she wants to clarify they were all meant for fun, and she’s heartened by how many users have rushed in to defend Hatch.

“We saw a lot of community jumping into the comments and saying, ‘Wait a minute, we missed the plot here!'” she says. “This is a Halloween-themed ad about their adult—not baby—product actually being the thing that will save you from the real evil: your phone. Your phone is actually keeping you up at night.’” To be clear, Hatch makes two devices, one specifically for kids and the other for adults. Any pop culture references, like Twilight, are exclusive to adults only via Hatch’s Restore 2 and 3 devices—they can’t be accessed on the Hatch Baby.

Then, a new trending topic arose about 48 hours later: “If you’re going to throw your Hatch device away, send it to me.”

Hatch took it and ran with it. “We used the cues of the community and sort of rode that wave with this idea of, ‘Hey, we know this is happening, and we wanted to address this while also pointing at having a little bit of fun with it,” Merani says.

Enter Hatch’s new “RePossession Program.” “We saw this overwhelming outreach of people who wanted to be ‘repossessed,'” Merani says, “so we were able to point people to our refurbishment program, to be able to keep those devices out of landfills and send ‘repossessed’ units out.”

So far, Hatch has had more than 10,000 related social media inquiries about receiving “repossessed Hatch devices,” and only 10 requests to send Hatch devices back to the company.

Ultimately, if you have a Hatch device and would like to send it back, you can contact customer service to arrange a return. On the other hand, you can now purchase refurbished machines (from the repossessed campaign and otherwise) here. No matter what side of the conversation you find yourself on, we can all agree on one thing: sleep is important, and you should definitely spend less time on your phone.
