Interplay of Configurational and Structural Transitions in the Course of Intercalation

Abstract

On the basis of a combination of the lattice gas and the linear elasticity theories, we argue that the major features of the intercalation isotherms can be well understood in terms of a coupling between the configurational and the structural transitions. Competitive effects of the internal and loading stresses are discussed. A simple model, operating with the hydrostatic parts of the stress and strain fields, is shown to be applicable to a quantitative description of experimental data on electrochemical intercalation into crystalline and layered host matrixes.

Correlation between Volume Change and Cell Voltage Variation with Composition for Lithium Intercalated Amorphous Films

“…In previous reports, 21,22 it has already been considered that volume changes upon intercalation have an influence on the cell voltage. In this model, it is assumed that there is an additional term to the host-guest free energy resulting from the elastic interaction 21 (Table 1) and eq 10 (blue dots).…”

Physical electrochemistry of nanostructured devices

“…111 Further studies 112 related the intercalation thermodynamics with the models for elastic interactions due to film expansion. 113,114 2.3 Depletion capacitance in nanowires Nanowires and nanotubes are drawing a tremendous attention due to their potential applications in various nanoscale devices. In particular ZnO can be easily induced to grow in the form of rods with high aspect ratio and nanometric dimensions.…”

Interplay of host volume variations and internal distortions in the course of intercalation into disordered matrices

“…͑10͒ with respect to ͑x͒ seems to be more constructive. In the previous study 17 the following modulating function has been considered:…”

“…This would allow us to analyze their impacts to the observed behavior. With this purpose we combine the distortive lattice gas model that has been successfully applied 17 to a description of volume dilatation in ordered intercalation compounds with the maximum information entropy approach. 18 The latter is an inductive inference method which is quite efficient 9 in estimating the host disorder from the experimental isotherm data.…”
