The development of solids that can conduct Li- and Na-ions as efficiently as a liquid at room temperature would revolutionize energy storage by completely eliminating the risk of fires from malfunctioning batteries and facilitating huge gains in the energy density. Only a handful of materials are known that can simultaneously meet the stringent requirements of (1) fast ionic conductivity, (2) low electrical conductivity, and (3) robust stability when in contact with metallic Li/Na. Our group is working to expand the number of known solid electrolytes by developing new compositions and exploring approaches to enhance the performance of known materials.
