Intercalation kinetics study of alkali-metal ions into TiS/sub 2/ using the pressure-jump technique
In aqueous suspensions of alkali-metal intercalation compounds of TiS/sub 2/, double relaxation were observed by using the pressure-jump technique with conductivity detection. For all intercalation compounds, the fast relaxation times decrease with particle concentration, while the slow ones are approximately constant. From the kinetic results obtained, the fast and slow relaxations are attributed to association-dissociation of the alkali-metal ions on the surface of the intercalation compounds and intercalation-deintercalation of their ions in the interlayers of the intercalation compounds, respectively. It was found that the order of association of rate constants of alkali-metal ions correspond to that of the mean time of movement of a water molecule between their ions and that deintercalation rate constant of a lithium ion in the interlayer is 1 order of magnitude faster than those of other alkali-metal ions. 12 references, 6 figures, 1 table.
