  Ni/MH二次电池负极材料的超高容量亚化学计量Zr基储氢合金的研制

  摘要：

  摘要 从电化学应用的放电容量的角度，制备并研究了一些亚化学计量的Zr基Laves相合金。ZrMn 2 基储氢合金经过精心的合金设计，通过改变其化学计量，同时替代或添加一些合金元素，Zr(Mn 0.2 V 0.2 Ni 0.6 ) 1.8 合金在储氢能力、氢平衡压力方面表现出较好的性能和电化学放电容量。为了提高放电容量和倍率性能，Zr 被 Ti 部分替代。Zr 1- x Ti x (Mn 0.2 V 0.2 Ni 0.6 ) 1.8 ( x =0.0, 0.2, 0.3, 0.4, 0.6)合金电极在30℃下的放电容量达到最大值，并随着Ti含量的增加而降低。鉴于电化学和热力学特性，合金电化学放电容量的最大现象的发生归因于降低储氢容量和增加倍率容量与钛分数之间的竞争。然而，随着钛含量的增加，放电容量随着重复电化学循环而急剧下降。从俄歇电子能谱 (AES) 对表面成分的分析来看，Zr 基合金中随着

ΔS A shows a weak dependence on the lattice parameter, but ΔS D shows no dependence at all. Both ΔH A ΔS A and ΔH D ΔS D display a strong dependence on the lattice parameters.

  The reactions of H-2(g) with the two-phase alloys (a) alpha-Zr + ZrMn2 + x and (b) alpha-Mn + ZrMn2 + x have been investigated. The homogeneity range of the Laves phase ZrMn2 + x intermetallic compound has been determined from the dependence of its hydrogen absorption behavior upon x and found to lie within the limits x = -0.3 +/- 0.1 and 1.0 +/- 0.1. Normally H-2(g) does not react with alpha-Zr below about 773 K, but it has been found that when it exists within the two-phase mixture, it reacts readily with hydrogen at room temperature. For alloys in the zirconium-rich two-phase field the hydrogen first reacts to form ZrH approximately 2 and then it reacts with the ZrMn2 + x phase. The former reaction leads to equilibrium pressures which are too small to measure, but the latter leads to measurable pressures. Results for alloys within the manganese-rich two-phase field, x greater-than-or-equal-to 1.0, are also reported. Calorimetric determinations of the enthalpies of reaction with hydrogen for several zirconium-rich alloys within the two-phase fields are reported for both the zirconium-rich and ZrMn2 + x phases.

  The reaction of hydrogen with ZrMn2 + x has been investigated using reaction calorimetry for x = -0.2, 0, 0.5 and 1.0. The enthalpies for hydride formation and decomposition are equal in magnitude over the two-solid-phase region; their magnitudes decrease with increasing x. Hysteresis is large for all these intermetallics, approximately 3.0 kJ (mol H)-1, and independent of x.
• An attempt to estimate the extent of the single phase region of the ZrMn2 phase by means of the X-ray diffraction-profile halfwidths

  A new method for determining the extent of single phase regions has been proposed. The chemical composition dependence of the powder X-ray diffraction (XRD)-profile halfwidths has been used for an estimation of the extent of the single phase region of the ZrMn2 phase in the Zr-Mn binary alloy system. The result obtained by this method has been compared with those provided by other known methods such as the standard powder XRD-pattern analysis, the chemical composition dependence analysis of the lattice parameters, the P-C-isotherm measurement and microstructure examination. This ''halfwidth'' method is a fully sensitive one by means of which the extent of the single phase region can be determined. The region extends approximately from ZrMn1.9 to ZrMn2.9, although the lower limit varies from ZrMn1.9 to ZrMn2.0 depending on the applied methods. The region obtained by this work is narrower than that indicated in the latest Zr-Mn binary phase diagram. Furthermore, an unidentified phase has been observed in the hyper-Zr alloys, besides the ZrMn2 and alpha-Zr phases. That phase is likely to be the ZrMn structure, which is perhaps stable at a high temperature and unstable at room temperature. (C) 1997 Elsevier Science S.A.
