Explanation

It is also called superionic conductor and solid electrolyte. The main body of materials is fast ionic conductor, which is a special kind of material with ionic conductivity. It is distinguished from the general ion conductor by its high electric conductivity and low activation energy. There are one-dimensional, two-dimensional, or three-dimensional channels available for ion migration in these substances; In addition, there is a very high defect concentration in the migration ion sublattice of fast ion conductors. This sublattice disorder can produce coordinated movement of ions, thus reducing the migration activation or conditioning energy of ions and making them have high electric conductivity. Fast ion conductors can be classified according to their mobility, such as cation conductors, anion conductors, lithium ion conductors, sodium ion conductor, etc; It can also be classified according to the existing form of its substance, such as crystalline ion conductor, amorphous (glassy) ion conductor, polymer ion conductor, etc. Fast ionic conductor is also called solid electrolyte because of its high ionic electric conductivity, which can play the role of elonrolyte. The appearance of solid electrolyte makes it possible for accumulator with high specific energy and large capacity. Hydrogen and oxygen plasma conductors can also be used as solid electrolyte for high-temperature fuel cell. Fast ion conductors can also be used to manufacture various ion selective electrodes, such as oxygen sensors, and various electrochemical devices, such as electrochromic displays, double layer capacitors, coulometers, etc.
