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.”

Houston space co. secures $4.8B NASA contract to provide communications, navigation services

near space exploration

Houston-based space exploration, infrastructure, and services company Intuitive Machines has snagged a deal with NASA that could be worth more than $4 billion.

Under the contract, Intuitive Machines (Nasdaq: LUNR, LUNRW) will supply communication and navigation services for missions in the “near space” region, which extends from the earth’s surface to beyond the moon.

The five-year deal includes an option to add five years to the contract. In total, the contract could be worth $4.82 billion. The initial round of NASA funding runs from October 2024 through September 2029.

“This contract marks an inflection point in Intuitive Machines’ leadership in space communications and navigation,” Steve Altemus, CEO of Intuitive Machines, says in a news release.

Under the deal, the company will deploy lunar relay satellites and provide communication and navigation services that play a role in NASA’s Artemis campaign to establish a long-term presence on the moon.

A highlight of the contract is the debut of Intuitive Machines’ lunar satellite constellation, a service that the company “believes is a strategic element in its vision to commercialize lunar activities.” The constellation will deliver data and transmission services and enable autonomous operations.

Earlier this month, Intuitive Machines secured its fourth contract with NASA’s Commercial Lunar Payload Services, or CLPS, program. The $116.9 million agreement will task Intuitive Machines with delivering six science and technology payloads, which will include one European Space Agency-led drill suite to the Moon’s South Pole.

Additionally in August, Intuitive Machines signed a deal with Houston-based launch services company SEOPS to offer lunar rideshare services. Under the deal, Intuitive Machines will enable SEOPS to deliver customers' payloads to the surface of the moon, as well as to Lagrange points and geostationary transfer orbits.

Chevron names inaugural cohort of Houston energy innovators

research ready

Anew program from Rice University and Chevron has named its inaugural cohort.

Funded by Chevron, the Chevron Energy Graduate Fellowship will provide $10,000 each to 10 Rice graduate students for the current academic year, which supports research in energy-related fields.

The Rice Sustainability Institute (RSI) hosted the event to introduce the inaugural cohort of the Rice Chevron Energy Graduate Fellowship at the Ralph S. O’Connor Building for Engineering and Science. Director of the RSI and the W. Maurice Ewing Professor in Earth, Environmental and Planetary Sciences, Carrie Masiello presented each fellow with a certificate during the ceremony.

“This fellowship supports students working on a wide range of topics related to scalable innovations in energy production that will lead to the reduction of carbon dioxide emissions,” Masiello says in a news release. “It’s important that we recognize the importance of intellectual diversity to the kind of problem-solving we have to do as we accomplish the energy transition.”

The work of the students focuses on creating "real-world, scalable solutions to transform the energy landscape,” per the Rice release. Recipients of the fellowship will research solutions to energy challenges that include producing eco-friendly hydrogen alternatives to fossil fuels and recycling lithium-ion batteries.

Some of the fellows' work will focus on renewable fuels and carbon-capture technologies, biological systems to sequester carbon dioxide, and the potential of soil organic carbon sequestration on agricultural land if we remove the additionality constraint. Xi Chen, a doctoral student in materials science and nanoengineering, will use microwave-assisted techniques to recycle lithium-ion batteries sustainably.

Rice President Reginald DesRoches began the event by stressing the importance of collaboration. Ramamoorthy Ramesh, executive vice president for research at Rice, echoed that statement appearing via Zoom to applaud the efforts of doing what is right for the planet and having a partner in Chevron.

“I’m excited to support emerging leaders like you all in this room, who are focused on scalable, innovative solutions because the world needs them,” Chris Powers, vice president of carbon capture, utilization and storage and emerging at Chevron New Energies and a Rice alum, says at the event. “Innovation and collaboration across sectors and borders will be key to unlocking the full potential of lower carbon energies, and it’s groups like you, our newest Chevron Fellows, that can help move the needle when it comes to translating, or evolving, the energy landscape for the future.”
