“…Considerable interest exists in lithium-metal-oxides due to their application potential as rechargeable battery electrodes 1 and electrochromic displays. 2 These oxides derive their interesting properties from the large stability region they have with respect to lithium content. In some materials, the ratio of lithium to metal ions can be varied between 0 and 1 without substantial changes to the structure of the material.…”

A study of the average voltage to intercalate lithium in various metal oxides is presented. By combining the ab initio pseudopotential method with basic thermodynamics the average intercalation voltage can be predicted without the need for experimental data. This procedure is used to systematically study the effect of metal chemistry, anion chemistry, and structure. It is found that Li is fully ionized in the intercalated compounds with its charge transferred to the anion and to the metal. The substantial charge transfer to the anion is responsible for the large voltage difference between oxides, sulfides, and selenides. Ionic relaxation, as a result of Li intercalation, causes nonrigid-band effects in the density of states of these materials. Suggestions for compounds that may have a substantially larger voltage than currently used materials are also presented.

“…Layered lithium cobaltites (Li x CoO 2 ) have attracted considerable attention in recent years. The interest has been stimulated not only by their practical applications as rechargeable battery electrode materials and electrochromic displays [1,2], but also by a need to understand the mechanism underlying their complex physical properties [3][4][5][6][7][8][9]. The fully lithiated compound with stoichiometry LiCoO 2 has a hexagonal structure belonging to theR m 3 space group.…”

Electronic structure and lattice dynamics of Li_xCoO₂single crystals

Spectroscopic ellipsometry and Raman scattering measurements of single-crystal Li x CoO 2 (x = 0.33, 0.43, 0.50, 0.53, 0.72, and 0.87) are reported. The room temperature optical absorption spectra for x values in the range of 0.33-0.72 exhibit three bands near 1.60, 3.35, and 5.20 eV. On the basis of firstprinciples calculations, the observed optical excitations were appropriately assigned. The chargetransfer absorption bands shift to higher energies in Li 0.87 CoO 2 because of symmetry-breakinginduced distortions of the hybridized Co-O orbitals with shifted oxygen 2p states. Furthermore, two Raman-active phonon modes, which display E g and A 1g symmetry, are sensitive to lithium doping. Upon cooling across 200 K, which is the antiferromagnetic phase transition temperature of Li 0.50 CoO 2 , large splitting of the E g mode and a discontinuous change in the frequency of the A 1g mode were observed. These results highlight the importance of spin-phonon coupling in Li 0.50 CoO 2 .

“…Recently, multifunctional windows, i.e., so-called “smart windows”, have attracted significant attention. With advances in electrochemical technologies, novel windows such as chromic windows, − liquid crystal devices (LCDs), − and suspended particle devices (SPDs) − have been developed. Chromic windows can generally be subdivided into electrochromic (EC) − and thermochromic (TC) − windows.…”

“…A specific layer in the EC window consisting of metal oxides plays a crucial role in the color-switching process, which is based on the redox reaction of the metal oxides. Tungsten oxide (WO 3 ) is primarily used as the metal oxide in EC windows. − …”

We have sequentially deposited layers of silver nanowires (AgNWs), silicon dioxide (SiO) nanoparticles, and polystyrene (PS) nanoparticles on uncoated glass by a rapid low-cost supersonic spraying method to create antifrosting, anticondensation, and self-cleaning glass. The conductive silver nanowire network embedded in the coating allows electrical heating of the glass surface. Supersonic spraying is a single-step coating technique that does not require vacuum. The fabricated multifunctional glass was characterized by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), ultraviolet-visible spectroscopy, and transmission electron microscopy (TEM). The thermal insulation and antifrosting performance were demonstrated using infrared thermal imaging. The reliability of the electrical heating function was tested through extensive cycling. This transparent multifunctional coating holds great promise for use in various smart window designs.
