Nanoengineered electrode material boosts cycling and efficiency in Li-metal batteries
Lithium metal (Li-metal) batteries are among the most promising alternatives to widely employed rechargeable lithium-ion (Li-ion) batteries, as they could store more energy and thus extend the battery life of many electronic devices. Despite their potential, existing Li-metal batteries have been found to be less stable than Li-ion batteries, while also exhibiting lower coulombic efficiencies (CE) and degrading faster over time.
In addition, the Li-metal electrodes integrated in these batteries tend to expand and contract when a battery is charging and discharging. These changes in volume can result in cracks and a loss of electrical contact, further hindering the batteries’ performance.
Researchers at Shandong University, Zhejiang University and other institutes recently introduced a new nanoengineered material that could be used as an electrode in Li-metal batteries, which does not expand or shrink during charging and discharging. The new material, presented in a paper published in Nature Nanotechnology, is comprised of reduced graphene oxide (rGO), a thin material that conducts electricity, and zinc oxide, a stable and electrochemically active ceramic.
“Our recent work stemmed from decades of frustration in the lithium metal battery field, namely that the highest capacity anode material consistently failed due to its infinite volume changes during cycling,” Hao Chen, co-senior author of the paper, told Tech Xplore. “These volume fluctuations rupture solid electrolyte interfaces and trigger irreversible corrosion, preventing the >99.9% coulombic efficiency (CE) essential for practical batteries.”
The main goal of this recent study by Chen and his colleagues was thus to realize an electrode material that does not change in volume and that entirely isolates lithium from the corrosive electrolytes inside a battery. The composite material they realized, based on rGO and ZnO, was found to prompt the formation of a durable solid-electrolyte interphase (SEI), the protective layer separating electrodes from electrolytes in battery cells.
“We designed a two-dimensional, continuous layered-cavity zero-volume-change complete-sealing rGO&ZnO host,” explained Chen. “Its architecture has two key features. First, Li plating/stripping occurs entirely within rigid cavities, eliminating destructive volume expansion. Second, a continuous host structure acts like corrosion-proof armor, entirely preventing electrolyte penetration and contact with Li.”
The material nanoengineered by Chen and his colleagues was found to successfully overcome the limitations of electrodes that are widely employed in Li-metal batteries. In initial tests, it was found to exhibit no changes in volume during charging and discharging, which is highly desirable and proved difficult to achieve so far.
“Our host enabled unprecedented Li cycling,” said Chen. “We attained a record efficiency of 99.99–99.9999% and a coulombic efficiency of almost 2,000 cycles—surpassing the critical >99.9% threshold for viable Li-metal batteries. We solved the core challenge of volume-change-driven Li degradation, demonstrating for the first time that near-perfect Li reversibility is achievable.”
The composite electrode material engineered by this team of researchers could soon be deployed in Li-metal batteries with varying compositions to further assess its potential and performance. In the future, it could contribute to the development of Li-metal batteries with high energy densities and ultra-long lifespans.
“Looking ahead, we are scaling this host design for commercial pouch cells while refining manufacturing processes,” added Chen. “We’re also adapting its zero-volume-change sealing concept to other battery chemistries (e.g., sodium-metal anodes) and exploring integrations with solid-state electrolytes to further enhance safety and energy density—aiming to accelerate real-world deployment through industry partnerships in the next 3–5 years.”

A Former Top Trump Official Is Going After Prediction Markets
Mick Mulvaney wants to be clear: He really likes gambling. “You’re talking to the only former member of Congress who’s won a poker tournament in Las Vegas,” he tells WIRED. When he was representing South Carolina in the US House of Representatives, he pushed for the state to allow sports betting.
Because of his background, Mulvaney, a former Trump administration official, says he can tell when something is gambling—and that the sports contracts on prediction markets fit the bill. “You know the old saying, if it walks like a duck and quacks like a duck, it’s a duck?” he asks. “If it looks like a sports bet, if it sounds like a sports bet, if it pays off like a sports bet, if it’s on a sporting event—it’s a sports bet.”
Mulvaney, who was President Trump’s acting White House chief of staff from 2019 to 2020, is now leading a new advocacy coalition called Gambling Is Not Investing, which will lobby for prediction markets to be regulated by state gambling laws. He joins a number of other prominent Republicans calling for similar rules. Earlier this month, former New Jersey Governor Chris Christie and current Utah Governor Spencer Cox both spoke out against the current federal approach to regulating prediction markets. (Christie also used the “quack like a duck” line.)
These developments are part of a fierce political battle over how prediction markets are regulated. On the federal level, the Commodity Futures Trading Commission (CFTC) oversees these platforms, which are currently classified as derivatives markets. While a traditional sportsbook will offer customers a chance to place a bet on which team will win or lose a game, a prediction market will offer an “event contract” on the outcome. Critics view the difference as little more than a loophole, and state authorities from across the country are currently pursuing lawsuits against prediction market companies like Kalshi, alleging that they violate state gambling laws. (While these markets offer event contracts on a wide variety of topics, sporting events are their most popular offerings.) “I love the CFTC, but they’re not set up to do this,” says Mulvaney.
Recently, a group of 23 Democratic Senators sent the CFTC a letter urging it to allow these court cases to play out. It did not appear to go over well; CFTC head Michael Selig insists that prediction markets are correctly classified, and that his agency has jurisdiction over the industry. After Selig released a video promising to see those who “challenge our authority” in court, the CFTC even took the unprecedented step of filing a brief in support of the cryptocurrency platform Crypto.com, which faces a lawsuit from Nevada regulators over its prediction market offering.
During the Biden Administration, the CFTC took a notably different approach to prediction markets, even fining Polymarket $1.4 million for failing to register as a derivatives market and temporarily blocking it from operating in the US.
Now, though, the agency’s friendlier approach appears to dovetail with the White House’s interest in the industry. The Trumps have numerous ties to the prediction market world. Truth Social, the social media platform majority-owned by President Trump and his family, is planning its own prediction market offering, reportedly called Truth Predict. Donald Trump Jr is an advisor to both Kalshi and Polymarket, and his venture capital firm has invested in the latter.
But the launch of Gambling Not Investing demonstrates that there is a growing wing of the Republican party that feels the prediction markets need more guardrails. Its founding member organizations include a number of conservative consumer advocacy groups, including Moms for America, Consumer Action for a Strong Economy, and Frontiers of Freedom.
Mulvaney is hopeful that he can make his case to the current White House. “Their default position is going to be to regulate less, not more. And I respect that,” he says. “But I also know that in the first Trump administration, when there were common sense reasons to do some regulation, that we did that.”

When the Internet Goes Dark, the Truth Goes With It
Alaqad says that because traditional media outlets pick and choose what to show their audiences, losing on-the-ground journalists means losing parts of the truth. “When the people are being silenced and censored, and they don’t have a space for them to talk or a platform to express what’s happening, and for us to see what’s happening through their eyes, there will always be limitations [on] how much we know,” she says.
In every crisis, when communication breaks down, accountability is lost and injustice becomes easier to ignore. “Injustice is super loud,” Alaqad says. “Justice needs to be louder.”
Targeted
Journalists are also silenced permanently. Reporters Without Borders (RSF) wrote in December 2025 that 67 media professionals were killed that year, 43 percent of whom were killed in Gaza by Israeli armed forces. The total number of journalists killed in Gaza since October 7, 2023 has risen to over 220, according to the RSF. The UN estimate sits at more than 260.
“When we look at it within the framework of imposing a ban on the foreign press entering Gaza now, more than two years into that war, when they are restricting the free movement of journalists within Gaza and into Gaza, when we are talking about an unprecedented massacre of journalists, the targeting of media offices and the targeting of communication infrastructure just becomes another piece of that puzzle, which aims at imposing a media blackout,” Dagher says. Israel has repeatedly denied claims that it targets journalists or media infrastructure.
“Killing journalists means killing and silencing the truth,” Alaqad says. In her experience, this strategy works on multiple levels—killing journalists means fewer people reporting on the ground, but equally, it turns journalists into a threat to the people. “This is also sending a message to the people that all journalists are a threat, don’t talk to journalists, stay away from journalists,” she explains.
She recalls her mother begging her not to wear her press vest and helmet. Meant to signify neutrality and protect journalists in the field, instead, it made her feel like a target. “It’s supposed to protect, but on the contrary, it actually puts risk on your life and even on your beloved ones and the ones around you,” she explains.
Alaqad says it was not always this way. Early on, people would greet journalists, offer them food, and thank them for their work. “After a couple of months, when they’d seen journalists getting targeted, Palestinians started treating journalists differently,” she says.
To report in Gaza was to work inside a landscape where time itself was unstable and not guaranteed. Plans rarely extended beyond daylight. Conversations ended abruptly. Addresses became memorials overnight. “The only certainty in Gaza is uncertainty,” Alaqad says.
She recalls interviewing families and planning to return the next day, only to find that the people she spoke with had been killed in airstrikes.
She has since left Gaza, and is pursuing a master’s degree in media studies at the American University of Beirut. She received the Shireen Abu Akleh Memorial Endowed Scholarship, named for the Palestinian journalist killed by Israeli forces in May 2022.
Digital Truths
Going viral on social media helped her reach people, but it also put her at risk. “It showed millions of people around the world what’s happening in Gaza, but at what cost? Being in Gaza could cost you your life, especially as a journalist,” she says.
Despite the reach of digital reporting, she does not trust its permanence. Accounts disappear, posts are removed and videos are lost. What is available today may be gone tomorrow.
