Fueling the future with new perovskite-related oxide-ion conductors

"a new hexagonal perovskite-related oxide, Ba7Ta3.7Mo1.3O20.15, which showed excellent ionic conduction at intermediate and low temperatures. "We aimed to design materials that allowed for the introduction of a large number of interstitial oxygens into their structure and showed high conductivity... These high-performance oxide-ion conductors could pave the way for the development of solid electrolytes for next-generation batteries and clean energy devices such as solid oxide fuel cells. (SOFCs)"
