One step closer to lithium metal batteries that function with minimal external pressure

A team of battery researchers led by the University of California San Diego and University of Chicago has developed a new methodology to produce the potentially game-changing thin-film solid-state electrolyte called lithium phosphorus oxynitride (LiPON). The team went on to implement their free-standing version of LiPON film in functional battery tests and found that it promotes a uniformly dense lithium metal electrochemical deposition under zero external pressure, with the aid of internal compressive stress and a gold seeding layer. This work, performed by a team of battery researchers led by the University of California San Diego and University of Chicago, was published in the journal Nature Nanotechnology on August 03, 2023.
