A research team is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.
A research team at Rice University led by James Tour, the T.T. and W.F. Chao Professor of Chemistry and professor of materials science and nanoengineering, is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.
Conventional recycling techniques typically involve breaking down battery materials into their elemental forms through energy-intensive thermal or chemical processes that are costly and have significant environmental impacts. Using FJH, the researchers heated battery waste to 2,500 Kelvin within seconds, creating unique features with magnetic shells and stable core structures. The magnetic separation allowed for efficient purification.
"Notably, the metal impurities were significantly reduced after separation while preserving the structure and functionality of the materials," Tour said."The bulk structure of battery materials remains stable and is ready to be reconstituted into new cathodes." The study was supported by the Air Force Office of Scientific Research, U.S. Army Corps of Engineers ERDC and Rice Academy Fellowship.Weiyin Chen, Yi Cheng, Jinhang Chen, Ksenia V. Bets, Rodrigo V.

In a world-first, researchers map a 4,200 km transatlantic flight of the painted lady butterflyIn October 2013, Gerard Talavera, a researcher from the Botanical Institute of Barcelona at CSIC, made a surprising discovery of painted lady butterflies on the Atlantic beaches of French Guiana—a species not typically found in South America. This unusual sighting prompted an international study to investigate the origin of these butterflies.

Researchers develop polymer fibers that can facilitate controlled, local drug deliveryMedical products such as ointments or syringes reach their limits when it comes to delivering medication locally—and above all in a controlled manner over a longer period of time. Empa researchers are therefore developing polymer fibers that can deliver active ingredients precisely over the long term.
