Early History of Solid State Ionics

Abstract

AbstractThough the term “Solid State lonics” was named originally by the present author early in the 1960s, solid ionic conductors which are involved in the field of Solid State lonics have been recognized since the mid-nineteenth century. However, room temperature high coniuctivity solid ionic conductors have been studied only after the 1960s. A field of Solid State lonics covers the stuaies of all phenomena of ions in solids, especially solids exhibiting high ionic and electronic-ionic mixed conductivities at fairly low temperatures below their melting points. The applications of these solids are also included in this fiela. Here, only the early history of high conductivity solid ionic conductors which have the longest history in the field of Solid State Ionics is described briefly.
