University of Maryland Energy Research Center project on solid-state Li-ion batteries will receive $1.2 million from the Energy Department as part of a major investment in technology research advancing efficient vehicles.  Researchers Eric Wachsman, Liangbing Hu, and Yifei Mo will utilize a multifaceted and integrated (experimental and computational) approach to solve the key issue in solid-state Lithium-ion batteries, interfacial impedance, with a focus on Garnet-based solid-state electrolytes.

Solid-state Li-ion batteries utilize a solid-state electrolyte, which has significantly improved safety as compared to current commercial Li-ion batteries, as the ceramic electrolyte is inflammable, as well as the ability to operate at greater voltage and thus obtain higher energy density. Through this project, UMERC researchers are developing new material structures to improve cyclability, coulumbic efficiency, and provide higher energy and power density.  Advancements in solid-state Lithium-ion battery technology will improve fuel efficiency of plug-in electric vehicles and reduce their costs. 

“Investments in the next generation of vehicle technologies will both strengthen our economy and lead to a more fuel efficient, clean energy future,” said Secretary Ernest Moniz.
