Solid state materials exhibiting fast ionic and mixed (ionic and electronic) conductivity are being considered for alternative energy conversion (fuel cells) and storage (batteries) devices. The functional physicalchemical properties of solid depend on nature of chemical species present. Large numbers of solids show ionic conduction while not all of them find application in practical solid state devices. The key requirements for useful solid electrolytes are high ionic and negligible electronic conductivity over the employed range of activity of the mobile species, and chemical stability against reaction with the adjacent cell components during the preparation and operation. These remain challenging for scientists to develop durable solid state ionic devices with high power density. In this talk, we will present current progress in the development of solid electrolytes and electrodes for solid oxide fuel cells (SOFCs), and all-solid-state Li ion batteries.
