In addition to gleaning new fundamental insights on LiPON, the research team also implemented the new free-standing version of the solid-state electrolyte in functional battery tests. The team reports that the thin-film FS-LiPON 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 finding gives valuable hints regarding interface engineering in bulk solid-state batteries. LiPON-based thin film batteries have shown great potential for wearables and other compact electronic devices with a gigantic market.
