Vanadium pentoxide thin films are prepared by the sol-gel route by dissolving V 2 O 5 powder (99.5% purity) in H 2 O 2 solution. The solution is spin-coated on glass substrates for optical (UV-VIS-NIR) and XRD analysis, and on ITOcoated glass substrates for electrochromic measurements. The samples are then annealed at 150 C for 1 hour. The resulting films have a yellow-orange color, typical of polycrystalline V 2 O 5 . XRD measurements have shown that after annealing in air at 400 C the structure of the films has a c-axis preferred orientation, the (0 0 1)-type planes lying parallel to the substrate. SEM analysis revealed a smooth surface. The films' optical and physical constants (n, a, Eg, the thickness d and the mean thickness inhomogeneity s) are calculated using a simple and accurate method based on the transmission spectrum alone. The films' electrochromism is studied using cyclic voltammetry (CV) and chronoamperometry in propylene carbonate solution containing 1 mol=l LiClO 4 . The films show reversible multichromism (yellow-green-blue) upon Li þ ion insertion=extraction. The absorbance of films colored at three different potentials is measured in the UV-VIS-PIR wavelength range, and this study shows that the changes in the optical absorption are consistent with the film color changes. Finally, the optical and electrochromic properties of the films prepared by this method are compared with those of our sputtered films already studied and with other works.

Abstract:This work presents the recent progress in nanostructured materials used as positive electrodes in Li-ion batteries (LIBs). Three classes of host lattices for lithium insertion are considered: transition-metal oxides V 2 O 5 , α-NaV 2 O 5 , α-MnO 2 , olivine-like LiFePO 4 , and layered compounds LiNi 0.55 Co 0.45 O 2 , LiNi 1/3 Mn 1/3 Co 1/3 O 2 and Li 2 MnO 3 . First, a brief description of the preparation methods shows the advantage of a green process, i.e., environmentally friendliness wet chemistry, in which the synthesis route using single and mixed chelators is used. The impact of nanostructure and nano-morphology of cathode material on their electrochemical performance is investigated to determine the synthesis conditions to obtain the best electrochemical performance of LIBs.

“…1 In recent years V 2 O 5 has also been used with intercalating Li ions for high-capacity solid-state batteries. [2][3][4][5] The applied research and industrial focus on catalysis and batteries involving V 2 O 5 has led to a substantial amount of atomic-scale theory studies focusing on the V 2 O 5 bulk [5][6][7][8][9][10][11][12] and its surfaces. [12][13][14][15][16] The bulk of V 2 O 5 has a stacked structure.…”

Sparse matter is characterized by regions with low electron density and its understanding calls for methods to accurately calculate both the van der Waals ͑vdW͒ interactions and other bonding. Here we present a first-principles density-functional theory ͑DFT͒ study of a layered oxide ͑V 2 O 5 ͒ bulk structure which shows charge voids in between the layers and we highlight the role of the vdW forces in building up material cohesion. The result of previous first-principles studies involving semilocal approximations to the exchangecorrelation functional in DFT gave results in good agreement with experiments for the two in-plane lattice parameters of the unit cell but overestimated the parameter for the stacking direction. To recover the third parameter we include the nonlocal ͑dispersive͒ vdW interactions through the vdW-DF method ͓M. Dion, H. Rydberg, E. Schröder, D. C. Langreth, and B. I. Lundqvist, Phys. Rev. Lett. 92, 246401 ͑2004͔͒ testing also various choices of exchange forms. We find that the transferable first-principles vdW-DF calculations stabilizes the bulk structure. The vdW-DF method gives results in fairly good agreement with experiments for all three lattice parameters.
