In this paper, we report the surprisingly low electrolyte/electrode interface resistance of 8.6 Ω cm(2) observed in thin-film batteries. This value is an order of magnitude smaller than that presented in previous reports on all-solid-state lithium batteries. The value is also smaller than that found in a liquid electrolyte-based batteries. The low interface resistance indicates that the negative space-charge layer effects at the Li3PO(4-x)N(x)/LiCoO2 interface are negligible and demonstrates that it is possible to fabricate all-solid state batteries with faster charging/discharging properties.

Calculations of the electronic structure and X-ray spectra of the MO{'-(M = Ti, V, Mn, Fe, CO, Ni) clusters, modeling the respective solid-state monoxides, have been performed by the X,-DV method. The main purpose of the present work was to investigate an influence of the resonant emission processes on the X-ray emission spectra of the monoxides. It has been shown, that resonant emission can appreciably affect the shape of the ML,, ,and, to an even greater degree, the MM,, ,-X-ray emission spectra of the 1.h.s. transition 3d-metal monoxides.

Surfaces of titanium dioxide in both rutile and anatase polymorphs have attracted significant attention in catalysis and photochemistry. The (110) orientation of rutile, and to a lesser extent other rutile orientations, have been studied on an atomic scale, yielding information on surface structure and chemical reactivity. In contrast, the thermal and photochemistry of well-defined, single-crystal anatase surfaces has not been investigated, largely because of the metastable nature of anatase, as well as the lack of availability of highquality surfaces. Here we describe a study of the adsorption and photoreactivity of an organic adlayer, trimethyl acetate (TMA), on structurally excellent anatase (001) epitaxial thin films grown by oxygen plasma assisted molecular beam epitaxy (OPAMBE). High-resolution scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), and photodesorption spectrometry have been used to study the chemisorption and ultraviolet (UV) light-induced photodecomposition of TMA in ultrahigh vacuum. UV light promotes hole-mediated photodecomposition of TMA, resulting in decarboxylation to yield tert-butyl radical and CO 2 . The photochemical rate constant is equal to that measured for OPAMBE grown rutile TiO 2 (110) surfaces.
