Rice University announced the formation of a new center focused on developing advanced membrane materials and separation technologies for the energy transition.

Known as the Rice Center for Membrane Excellence, or RiCeME, the center will aim to secure funding to develop more efficient and sustainable membrane separation practices and advance next-generation membrane materials, which are essential in energy conversion processes.

The center, part of Rice's Water Technologies Entrepreneurship and Research, or WaTER Institute, also plans to drive water reuse and resource recovery solutions, perform bench-scale testing and pilot-scale demonstrations, and even host workforce development workshops and symposia on membrane science and technology.

The announcement was made during the Rice Global Paris Center Symposium in Paris.

RiCeME will be led by Menachem Elimelech, the Nancy and Clint Carlson Professor in Civil and Environmental Engineering and Chemical and Biomolecular Engineering at Rice. His research focuses on membrane-based processes, advanced materials and nanotechnology.

“Houston is the ideal place to drive innovation in membrane separation technologies,” Elimelech said in a news release. “Membranes are critical for energy-related separations such as fuel cells, carbon capture and water purification. Our work will enhance efficiency and sustainability in these key sectors.”

RiCeME will work on building partnerships with Houston-area industries, including oil and gas, chemical, and energy sectors, according to the release. It will also rely on interdisciplinary research by engaging faculty from civil and environmental engineering, chemical and biomolecular engineering, materials science and nanoengineering, and chemistry departments at Rice.

“Breakthroughs in membrane technology will play a crucial role in addressing energy and sustainability challenges,” Ramamoorthy Ramesh, executive vice president for research at Rice, said in a news release. “RiCeME’s interdisciplinary approach ensures that our discoveries move from the lab to real-world applications, driving innovation at the intersection of science and industry.”.

Houston scientists discover breakthrough process for lithium-ion battery recycling

researching for the future

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.”
