A team of researchers at the University of Maryland Energy Research Center and A. James Clark School of Engineering have announced a transformative development in the race to produce batteries that are at once safe, powerful, and affordable. The researchers are developing game-changing solid-state battery technology, and have made a key advance by inserting a layer of ultra-thin aluminum oxide between lithium electrodes and a solid non-flammable ceramic electrolyte known as garnet. Prior to this advance, there had been little success in developing high-performance, garnet-based solid-state batteries, because the high resistance, between the garnet electrolyte and electrode materials limited the flow of energy or current.
The ultra...
