abstract
The structural, thermodynamic and transport properties of lithium and sodium intercalated dichalcogenides are summarized. They have an unusual layered structure, an extremely low alkali-metal chemical potential over a wide compositional range, and an extremely high alkali-metal chemical diffusivity. With such properties these compounds are attractive electrode materials. To assess their potential applications in high energy density batteries, recent electrochemical cell investigations using either lithium-intercalated or sodium-intercalated TiS2 electrodes are discussed. 1982.
