Also called glassy state ion conductor, it is a fast ion conductor with amorphous structure. Compared with crystalline ionic conductor, amorphous (glassy) ion conductor has lower electric conductivity but is isotropic. Its composition and components can vary in a large range, and it is easy to process and shape, which is suitable for making films, thus greatly reducing the volume resistance of materials. Amorphous ion conductor has a highly disordered three-dimensional network structure. Alkali metal, alkaline earth metal or other metal ions are distributed in the network holes to participate in conduction. Common conduction ions are Li+, Ag+.
