Metal Chalccgenides As Reversible Electrodes

Abstract

Certain transition metal chalcogenides are promising materials for use as cathodes in nonaqueous batteries involving the intercalation of alkali metals, notably lithium, into these layered compounds. The electrochemical behavior of these chalcogenides depends on various properties such as structure, stoi-chiometry, electrical conductivity, crystal morphology, etc. The influence of these properties and of the ultimate practical application of the battery on the selection of the cathode material is discussed. The battery properties of the chalcogenides are compared with those of other promising cathode materials, especially V6O13. © IUPAC
