- 소개/요약Solid-state ionics provides scientific support for a wide variety of advanced electrochemical devices such as batteries, fuel cells, chemical sensors, gas separation membranes and ionic switches. Numerous solids with high ionic conductivity at room temperature are extensively used in technological applications and are named as fast ionic conductors. One of the applications of fast ionic conductors is used as electrolytes in battery applications; hence the fast ionic conductors are also referred as solid electrolytes. Solid electrolytes are having some advantages in electrochemical devices against the liquid electrolytes such as longer life, high energy density, less possibility of leakage, chemical stability, etc. Solid electrolytes are first discussed by Faraday at the end of the nineteenth century. Generally, these solid electrolyte materials are commonly featured as (1) crystal bonding is ionic in nature, (2) electrical conductivity is high (10–1 to 10–4 S/cm), (3) principle charge carriers are ions, (4) the electronic conductivity is negligible, (5) low activation energy for ion migration and (6) special crystal structure with open tunnels or channels through which the mobile ions move.
