“…For example, comparison of observed electric modulus spectra with those derived from empirical functions such as those of ColeCole (CC) [29] and Davidson-Cole (DC) [30] yields the notable result that the q * (ix) spectrum calculated from the DC form for M * (ix) is remarkably well described by the CC function [25], so that the excellent fits of the CC function to the complex impedance data reported for alkali silicate glasses by Ravaine and Souquet [31] and others are consistent with the excellent DC fits to M * (ix) data for the same alkali silicates demonstrated by Hodge and Angell [32]. A comparison between the two is shown in Fig.…”

“…The linear relation between average time and inverse of the conductivity 0[0] for all compositions of the B20]-Li20 thin-films and all temperatures is shown III Figure 4.32. This relation is often found in homogeneous dielectrics and nonhomogeneous conductors [146][147][148][149]. The observed bulk conductivity exhibits a frequency dependence if 0local varies from one micro-region to the other.…”

“…The migration of mobile ions is described by the conductivity relaxation time formalism [144]. The existence of the distribution of the relaxation times in disordered solids is commonly accepted [144][145][146]. The physical picture of the distribution of the relaxation times in solid electrolyte is attributed to the effective random potential acting on a mobile charge.…”

The purpose of this chapter is to introduce the area of solid-electrolyte thin-films and to discuss the various process/property/applications relationships which have been developed in this field. Thin-film technology is examined from the interrelated viewpoints of product application, materials structure/properties relationships, and manufacturing-deposition methods. Special emphasis is given to the thin-film materials properties of lithium-borate glasses, which are likely to have an impact on electrochemical device performance, coupled with the various techniques employed to control those properties.Thin-films form an integral part of products which cannot be made using bulk components. For some, this is because the films themselves possess unique properties which cannot be duplicated in bulk [1]. In still others, the thickness of a material may impart special functional advantages. The use of thin-film solid-oxide electrolytes in low temperature fuel cells is one such potential example [2].The concept of reducing the internal resistance of solid-state battery was the first reason for the use of thin-film techniques in battery technology and has been invoked many times by investigators attempting to use low-conducting materials. The use of thin-film technology for the formation of lithium-microbatteries offers various advantages: (i) thin-film technology is widely used in advanced microelectronics, (ii) thinning of layers gives a lower electrical resistance in the transverse direction, (iii) thin-film technology provides a clean surface for the compound and may improve the electrode-electrolyte interface contact by reducing the interface resistance, (iv) film deposition of alkali metals such as lithium is easy, (v) film deposition of lamellar compound allows the orientation of the layers with the van der Waals planes perpendicular to the separator surface, (vi) deposition of the C.

The effective medium theory of diffusion in topologically disordered systems is reviewed with emphasis on the description of disorder induced anomalous diffusion. The effective medium approximation (EMA), for which a new derivation is given, is shown to provide a reliable and simple scheme to discuss the diffusive motion of particles in disordered systems such as electrons in the localized energy region of disordered semiconductors or ions in amorphous solids. Explicit calculations for some pertinent models are presented and the consequences of anomalous diffusion to a.c. conductivity, transient photoconductivity, neutron scattering and NMR data are discussed.
