Abstract: Ceramic materials exhibiting fast ionic conduction are being considered for electrochemical energy storage devices, including batteries and capacitors. Among them, rechargeable lithium-ion batteries (LIBs) have received much attention due to their high volumetric and gravimetric energy densities and their wide range of applications. Currently employed liquid organic electrolytes in LIBs have several disadvantages such as flammability, poor electrochemical stability and toxicity. Recent research on electrolytes for LIBs has been focused on developing thermally stable solid electrolytes with desired physical and chemical properties. Several inorganic electrolytes, including NASICON, LISICON, perovskite, and garnet-type materials are being developed for all-solid-state lithium batteries. The key requirements for practical solid electrolytes are high ionic and negligible electronic conductivity over the employed range of activity of mobile species, and chemical stability against reaction with both high cathodes and elemental anodes. Here, we report advanced ceramic electrolytes for application in solid-state Li batteries together with designing aspects of useful solid electrolytes and electrodes.
