Abstract:  Solid electrolyte is an ionic conductor and an electronic insulator.  Large numbers of inorganic and organic materials exhibit fast ionic conduction. These solid electrolytes find potential applications in numerous solid-state ionic devices, including solid oxide fuel cells (SOFCs), high energy density Li ion batteries, and gas sensors. The general requirements for practical solid electrolytes are high ionic and negligible electronic conductivity over the employed range of activity of the mobile species, chemical stability against reaction with the adjacent components during the operation as well as the preparation of devices. These requirements make remaining challenges for the development of solid-state ionic devices for efficient operation with a high power density and a long-term stability. In this talk, current trends in the development of solid electrolytes and electrodes for SOFCs, and lithium ion batteries will be discussed.
