US Army partners with Brown University to study SEI on silicon anodes
The US Army Research Laboratory (ARL) and Brown University researchers have teamed up to study the solid electrolyte interphase (SEI) layer that forms on the anodes of lithium-ion batteries, with particular emphasis on experimental silicon anodes. The Army is working to replace its alkaline and nickel-metal hydride field batteries with Li-ion batteries. “The Army is… Read more »
Penn State professor wins grant to develop self-healing layers for Li metal anodes
Donghai Wang, who leads the Energy Nanostructure Laboratory at Penn State, has won a $1.1-million grant from the DOE’s Vehicle Technologies Office to develop a new lithium-ion conductor that will prevent the formation of dendrites, the bane of lithium metal anodes. Wang and his team plan to use thin layers of nanostructured hybrid materials to… Read more »
New catalyst advances lithium-air battery tech
Images from Field Emission Scanning Electron Microscope (FESEM) show catalyzed cells exhibiting longer cycle life than uncatalyzed cells under similar cycling conditions. Credit: Ates, M. N., et al. (2016) Lithium-air batteries, which have the highest theoretical energy density of all known battery devices, could revolutionize the energy economy. However, there are several technical challenges to… Read more »
Water-in-salt electrolyte could enable high-voltage aqueous Li-ion chemistries
A team of researchers from the University of Maryland (UMD) and the US Army Research Laboratory (ARL) have devised what they call a “water-in-salt” electrolyte that could offer power, efficiency and longevity comparable to Li-ion batteries, but without the toxic chemicals and fire risk. In “Water-in-salt electrolyte enables high-voltage aqueous lithium-ion chemistries,” published in the… Read more »
Cambridge scientists claim promising lithium-oxygen battery advancements
Cambridge scientists have developed a working demonstrator of a lithium-oxygen battery that is more than 90% efficient, and can be recharged more than 2,000 times. Lithium-oxygen, or lithium-air, has been touted as the ultimate battery technology, because its theoretical energy density is ten times that of lithium-ion solutions. In “Cycling Li-O2 Batteries via LiOH Formation… Read more »
