The structure and electrochemical properties of a new low cobalt hydrogen storage electrode alloys La1-xLixNi3.2Co0.3Al0.3 (0≤x≤0.2) were investigated with a different additions of Li in replacement of La. With the increase of Li contents the maximum discharge capacity increases from 240 mAh·g-1(x=0) to 328.4 mAh·g-1(x=0.1) and the cycle stability is improved correspondingly. The capacity decay can remain 28.6% (x=0.2) after 230 charge/discharge cycles. The high rate discharge(HRD) ability of the alloys(x≤0.1) is improved and the best HRD is 34.1%(x=0.1) under the discharge current density 1200 mA·g-1. It is found that the prepared alloys are basically composed of LaNi5 as matrix phase and LaNi3 as second phase(x≤0.1). But the abundance of LaNi3 phase dramatically decreases with increasing x. When x=0.2, a new phase Al(NiCo)3 is formed.

稀有金属材料与工程 2006年第12期35卷 1983-1986页

作者：刘社社张鹏魏学东柳永宁朱杰武西安交通大学金属材料强度国家重点实验室陕西西安710049

为了改善Ti基贮氢合金的电化学性能,采用XRD,SEM及EDS分析了Ti0.3Zr0.225V0.25Mn0.3-xNi0.45+x(x=0,0.05,0.10,0.15,0.20,0.25)贮氢合金的相结构及相成分,并研究了合金的电化学性能。结果表明,合金均由六方结构的C14型Laves主相和立方结构的C15型Laves第二相构成;随着Ni替代量x的增大,合金的活化性能降低,而循环稳定性得到一定程度的改善。当Ni替代量x=0.05时,合金的放电容量达到最大,为426mAh/g,显示出很大的应用潜力。

Single-walled carbon nanotubes （SWCNTs） illuminated by white light should appear colored due to resonance Rayleigh scattering. However, true-color imaging of SWCNTs on substrates has not been reported, because of the extremely low scattering intensity of SWCNTs and the strong substrate scattering. Here we show that Rayleigh scattering can be greatly enhanced by the interface dipole enhancement effect. Consequently colorful SWCNTs on substrates can be directly imaged under an optical microscope by wide field supercontinuum laser illumination, which facilitates high throughput chirality assignment of individual SWCNTs. This approach, termed ＂Rayleigh imaging microscopy＂, is not restricted to SWCNTs, but widely applicable to a variety of nanomaterials, which enables the colorful nanoworld to be explored under optical microscopes.
