Solid Electrolytes for Multivalent Cations
Abstract
The Beta and Beta aluminas are well appreciated as a unique family of materials with remarkable structural, transport and optical properties. Their rich ion exchange chemistry make it possible to chemically 'tune' the mobile ion composition so that specific properties are developed within the Beta alumina framework. As ionic conductors, the Beta aluminas are the first solids to exhibit high conductivity for divalent and trivalent cations, while transition- metal and lanthanide-containing Beta aluminas exhibit some exceptional optical properties. The present research program builds upon the structure/property relationships that we have established for the multivalent Beta aluminas. The overall objective of the research is to utilize the Beta and Beta aluminas family of materials as a model system in which to design and synthesize compounds with pre-determined properties.
