For future Li-ion battery applications the search for both new design concepts and materials is necessary. The electrodes
of the batteries are always in contact with electrolytes, which are responsible for the transport of Li ions during the charging
and discharging process. A broad range of materials is considered for both electrolytes and electrodes so that very different
chemical interactions between them can occur, while good cycling behavior can only be obtained for stable solid-electrolyte
interfaces. X-ray photoelectron spectroscopy (XPS) was used to study the most relevant interactions between various electrode
materials in contact with different electrolyte solutions. It is shown how XPS can provide useful information on reactivities
and thus preselect suitable electrode/electrolyte combinations, prior to electrochemical performance tests. 相似文献

Explicitly correlated coupled cluster theory at the CCSD(T)-F12x (x = a, b) level [T. B. Adler et al., J. Chem. Phys. 127, 221106 (2007)] has been employed in a study of the potential energy surfaces for the complexes H(2)C(3)H(+) · Ar and c-C(3)H(3)(+) · Ar. For the former complex, a pronounced minimum with C(s) symmetry was found (D(e) ≈ 780 cm(-1)), well below the local "H-bound" minimum with C(2v) symmetry (D(e) ≈ 585 cm(-1)). The absorption at 3238 cm(-1) found in the recent infrared photodissociation spectra [A. M. Ricks et al., J. Chem. Phys. 132, 051101 (2010)] is, thus, interpreted as an essentially free acetylenic CH stretching vibration of the propargyl cation. A global minimum of C(s) symmetry was also obtained for c-C(3)H(3)(+) (D(e) ≈ 580 cm(-1)), but the energy difference with respect to the local C(2v) minimum is only 54 cm(-1). 相似文献

Self-assembled nanoporous tin-based hybrid thin films prepared by the sol-gel method from organically-bridged ditin hexaalkynides detect hydrogen gas from 50 to 200 °C at the 200-10,000 ppm level. This finding opens a fully new class of gas-sensing materials as well as a new opportunity to integrate organic functionality in gas sensing metal oxides. 相似文献

3 (YAP) thin films as a promising material for application in a planar waveguide laser has been studied. The films have been
grown on sapphire(0001) and YAP(001) substrates by laser ablation. The influence of the substrate temperature and ambient
oxygen pressure on the crystalline structure, concentration of Nd incorporated into films, and consequent luminescence spectra
were investigated. The waveguiding properties were observed and refractive index of the films was evaluated.

We prove an abstract norm equivalence for a two-level method, which allows us to reduce the construction of preconditioners for nonconforming finite element discretizations to known cases of conforming elements.
