Ion exchange chemistry of layered metal chalcogenides is not explored much compared to that of metal oxides. These are by and large limited to alkali ion-containing transition metal dichalcogenides A MQ (A=alkah ion M=early transition metal from groups 4, 5 and 6 Q=S, Se, Te) [11-13]. The hydrolytic instability of these materials prohibits ion exchange. KMS-1 is a layered sulfide (Fig. 10.3.2) of the formula...

Although there are numerous families of lamellar solids, only a handful of them exhibit the kind of versatile intercalation chemistry that forms the basis of this book. In arriving at the content of this volume, the editors have accurately identified six classes of versatile layered compounds that are at the forefront of materials intercalation chemistry, namely, smectite clays, zirconium phosphates and phos-phonates, layered double hydroxides (known informally as hydrotalcites or anionic clays ), layered manganese oxides, layered metal chalcogenides, and lamellar alkali silicates and silicic acids. Graphite and carbon nanotubes have not been included, in part because this specialty area of intercalation chemistry is limited to one or two molecular layers of comparatively small guest species that are capable of undergoing electron transfCT reactions with the host structure.

Many layered metal chalcogenides may be used as a cathodic (positive) insertion elecUode in rechargeable alkali metal batteries because of their ability to reversibly intercalate alkali metal cations [11,12,96], Any useful electrode material must fulfill most of the following requirements ...
