With the rise of electric vehicles, every ounce of lithium in lithium-ion batteries is precious. A team of scientists from Rice University has figured out a way to retrieve as much as 50 percent of the material in used battery cathodes in as little as 30 seconds.

Researchers at Rice University’s Nanomaterials Laboratory led by Department of Materials Science and NanoEngineering Chair Pulickel Ajayan released the findings a new study published in Advanced Functional Materials. Their work shows that the process overcomes a “bottleneck” in lithium-ion battery recycling technology. The researchers described a “rapid, efficient and environmentally friendly method for selective lithium recovery using microwave radiation and a readily biodegradable solvent,” according to a news release.

Past recycling methods have involved harsh acids, and alternative eco-friendly solvents like deep eutectic solvents (DESs) at times have not been as efficient and economically viable. Current recycling methods recover less than 5 percent of lithium, which is due to contamination and loss during the process.

In order to leach other metals like cobalt or nickel, both the choline chloride and the ethylene glycol have to be involved in the process, according to the researchers at Rice. The researchers submerged the battery waste material in the solvent and blasted it with microwave radiation since they knew that of the two substances only choline chloride is good at absorbing microwaves.

Microwave-assisted heating can achieve similar efficiencies like traditional oil bath heating almost 100 times faster. Using the microwave-based process, Rice found that it took 15 minutes to leach 87 percent of the lithium, which differs from the 12 hours needed to obtain the same recovery rate via oil bath heating.

“This method not only enhances the recovery rate but also minimizes environmental impact, which makes it a promising step toward deploying DES-based recycling systems at scale for selective metal recovery,” Ajayan says in the release.

Due to rise in EV production, the lithium-ion battery global market is expected to grow by over 23 percent in the next eight years, and was previously valued at over $65 billion in 2023.

“We’ve seen a colossal growth in LIB use in recent years, which inevitably raises concerns as to the availability of critical metals like lithium, cobalt and nickel that are used in the cathodes,” the study's co-author, Sohini Bhattacharyya, adds. “It’s therefore really important to recycle spent LIBs to recover these metals.”

Mark Cuban calls AI ‘the greater democratizer’ for young entrepreneurs

eyes on AI

Texas billionaire Mark Cuban—whose investment portfolio includes Houston-based Holliball, a startup that makes and sells large inflatable holiday ornaments—believes AI is leveling the playing field for budding low-income entrepreneurs.

At the recent Clover x Shark Tank Summit in Las Vegas, the Shark Tank alum called AI “the greater democratizer.”

Cuban told Axios that free and low-cost AI tools enable disadvantaged teenagers to compete with seasoned professionals.

“Right now, if you’re a 14- to 18-year-old and you’re in not-so-good circumstances, you have access to the best professors and the best consultants,” Cuban said. “It allows people who otherwise would not have access to any resources to have access to the best resources in real time. You can compete with anybody.”

While Cuban believes AI is “the great democratizer” for low-income young people, low-income workers still face hurdles in navigating the AI landscape, according to Public Works Partners, an urban planning and consulting firm. The firm says access to AI among low-income workers may be limited due to cost, insufficient digital literacy and infrastructure gaps.

“Without adequate resources and training, these workers may struggle to adapt to AI-driven workplaces or access the educational opportunities necessary to acquire new skills,” Public Works Partners said.

Texas 2036, a public policy organization focused on the state’s future, reported in January AI jobs in Texas are projected to grow 27 percent over the next decade. The number 2036 refers to the year when Texas will celebrate its bicentennial.

As for the current state of AI, Cuban said he doesn’t think the economy is witnessing an AI bubble comparable to the dot-com bubble, which lasted from 1998 to 2000.

“The difference is, the improvement in technology basically slowed to a trickle,” Cuban said of the dot-com era. “We’re nowhere near the improvement in technology slowing to a trickle in AI.”

CPRIT hires MD Anderson official as chief cancer prevention officer

new hire

The Austin-based Cancer Prevention and Research Institute of Texas, which provides funding for cancer research across the state, has hired Ruth Rechis as its chief prevention officer. She comes to CPRIT from Houston’s University of Texas MD Anderson Cancer Center, where she led the Cancer Prevention and Control Platform.

Before joining MD Anderson, Rechis was a member of the executive leadership team at the Livestrong Foundation, an Austin-based nonprofit that supports people affected by cancer.

“Ruth has widespread connections throughout the cancer prevention community, both in Texas and across the nation,” CPRIT CEO Kristen Doyle said in a news release. “She is a long-term passionate supporter of CPRIT, and she is very familiar with our process, programs, and commitment to transparency. Ruth is a terrific addition to the team here at CPRIT.”

Rechis said that by collaborating with researchers, policymakers, public health leaders and community partners, CPRIT “can continue to drive forward proven prevention strategies that improve health outcomes, lower long-term costs, and create healthier futures for all.”

At MD Anderson, Rechis and her team worked with more than 100 organizations in Texas to bolster cancer prevention initiatives at clinics and community-based organizations.

Rechis is a longtime survivor of Hodgkin lymphoma, a type of cancer that affects the lymph nodes, which are part of a person’s immune system.
