Applications of solid-state ionic materials

Solid-state ionic materials have been extensively developed and applications of solid electrolytes as well as insertion compounds have begun to converge into a coherent field during the last 10 years. Various designs of working devices are outlined in this chapter with the emphasis on all solid-state configurations. The large number of references reflects the great interest of researchers in energy storage devices, sensors, and optical and other electrochemical applications of solid-state ionics. For most types it is mentioned whether they are commercially available, items of intense current development, or one of the hot new research items.
