Operando study of all solid state batteries

I’m pleased to announce that Hongli Zhu’s group and ours have received an NSF award to study and improve interfacial phenomena in all solid state batteries. From the abstract:

The specific objective of this research is to improve metal sulfide stability in solid-state electrolytes for the application of all solid-state lithium batteries. In pursuit of this objective, the fundamental mechanisms of metal sulfide ion conduction and interface reactivity will be interrogated by operando characterization carried out on realistic, fully operational battery cells.

Hongli’s group does material engineering of solid state electrolytes (SSEs), while my group specializes in operando characterization, using X-rays and various other techniques. The announcement from Northeastern is here, and the NSF award page is here. We start this fall and are looking forward to it.

The Gallaway lab settles in

The lab is coming along, and it’s starting to have a lot of batteries in it, plugged in and cycling away. But let me talk for a minute about our group. We’ve got a great collection of people that has formed, all trying to learn something. The picture above shows Josie and Sydney, who are making Li-ion batteries. The picture below shows group meeting from this last academic year. Nick, Alyssa, Ben, Matt, and Zhicheng are debating something. Research and knowledge are why we’re here, but the people involved are the most important part.
