A layer structured titanate Cs_xTi_<2-x/2>Zn_<x/2>O_4 (x=0.70) with a lepidocrocite-related structure has been prepared by a solid state reaction using Cs_2CO_3, anatase type TiO_2 and ZnO at 800℃. Ion exchange reactions have been studied in aqueous solutions. The single phases of lithium, sodium and hydrogen ion exchange products were obtained from Cs_<0.70>Ti_<1.65>Zn_<0.35>O_4. They contain interlayer water and the host layer was retained on the reactions. Cs^+ in the interlayer space was ion exchanged up to 100%. Zn^<2+> in the intralayer was also ion exchanged with H^+ in H_2SO_4 solution. The Li^+ exchange product was electrochemically active in a lithium battery.
