  Solution calorimetry has yielded ΔtHmo = −(2.53±0.05) kJ·mol−1 for the reaction: 12Na2SO4(cr, V) + 12Li2SO4(cr, α) = NaLiSO4(cr) at 298.15 K. The standard molar enthalpy of formation is ΔfHmo(NaLiSO4, cr, 298.15 K) = −(1414.31 ± 0.88) kJ·mol−1. Drop calorimetry (350 to 1150 K) has been used to determine enthalpy increments relative to 298.15 K of NaLiSO4 and the heat capacity to 1200 K has been deduced

  suitability of LiNaSO 4 for use as a proton-conducting electrolyte in H 2 -O 2 fuel cells was investigated. Experimental results indicated that fuel cell performance is not stable under the operating conditions. The open-circuit voltage of the fuel cell and conductivity of LiNaSO 4 vary with testing time. Thermodynamic analysis and X-ray diffraction tests demonstrated that LiNaSO 4 reacted with hydrogen

  研究了 LiNaSO 4 在 H 2 -O 2 燃料电池中用作质子传导电解质的适用性。实验结果表明，燃料电池在运行条件下性能不稳定。燃料电池的开路电压和LiNaSO 4 的电导率随测试时间而变化。热力学分析和X射线衍射测试表明，LiNaSO 4 在燃料电池工作温度下与氢气发生反应，产生了一些新材料，如Na 2 S、LiOH和NaOH。因此，LiNaSO 4 不适合作为以氢为燃料的燃料电池应用的电解质。
• Fast Cation Conduction and Anion Rotational Disorder in the High-Temperature Phase of Lithium Sodium Sulfate

  Quasielastic neutron scattering and high-frequency (10 MHz to 60 GHz) conductivity measurements have been performed on the high-temperature phase of LiNaSO₄, a typical representative of a group of simple inorganic salts exhibiting both fast-cation conduction and anion rotational disorder.

  The quasielastic neutron spectra are composed of two Lorentzian contributions which are consistently attributed to cation diffusion and anion rotational motion. The narrower component is dominated by incoherent sodium scattering; it shows the characteristics of jump diffusion with a jump distance of 3.8 Å and residence times between 14 ps and 22 ps.

  The broader quasielastic component reflects the anion dynamics with typical reorientation times of 2 ps. The reduced Q-dependent intensities are in good agreement with the model of isotropic diffusion. The quasielastic intensity in the low Q regime (Q < 1 Å⁻¹) indicates the involvement of cations in the reorientational motion of the translationally fixed anions.

  Analysis of the conductivity data in terms of diffusivities points to an unusual cation conduction mechanism: the Haven ratio, H _R = D ^*/D _σ, turns out to be considerably larger than one. This behavior, rarely observed in a typical fast ion conductor, can be traced back to a charge correlation factor which is clearly smaller than unity, indicating that charge transport is less effective than tracer transport in this material.

  摘要 对 LiNaSO4 的高温相进行了准弹性中子散射和高频（10 MHz 至 60 GHz）电导率测量，LiNaSO4 是一组同时表现出快速阳离子传导和阴离子旋转无序的简单无机盐的典型代表。 准弹性中子谱图由两个洛伦兹分量组成，这两个分量始终归因于阳离子扩散和阴离子旋转运动。较窄的分量由非相干钠散射主导；它显示了跃迁扩散的特征，跃迁距离为 3.8 Å，停留时间介于 14 ps 和 22 ps 之间。 较宽的类弹性成分反映了阴离子动力学，其典型的重新定向时间为 2 ps。随 Q 值降低的强度与各向同性扩散模型十分吻合。低 Q 值（Q < 1 Å-1）下的类弹性强度表明阳离子参与了平移固定阴离子的重新定向运动。 根据扩散率对电导率数据的分析表明了一种不同寻常的阳离子传导机制：哈文比（H R = D */D σ，结果远远大于 1。在典型的快速离子导体中很少观察到这种行为，它可以追溯到电荷相关因子，该因子明显小于 1，表明在这种材料中，电荷传输不如示踪传输有效。

  Abstract We have stabilized, through additive (Li2CO3) aided-quenching of the melt, a disordered hexagonal form of LiNaSO4 ( a = 7.635 A , c = 9.861 A ) that exhibits an unusually large conductivity (σ). Typically logσT = −4.5 at 500 K. The conductivity data in the temperature range 30–300°C into a two-slope Arrhenius plot with activation energies 0.95 eV and 0.11 eV. The conductivity enhancement is

  摘要 我们通过添加剂 (Li2CO3) 辅助淬火稳定了 LiNaSO4 (a = 7.635 A , c = 9.861 A ) 的无序六边形形式，具有异常大的电导率 (σ)。通常在 500 K 时 logσT = -4.5。 将 30–300°C 温度范围内的电导率数据转换为具有 0.95 eV 和 0.11 eV 活化能的双斜阿伦尼乌斯图。通过添加离子 (CO32-) 稳定的 SO42- 无序淬火定性地解释了电导率的增强。DSC、IR 和 ESR 光谱为这种阴离子无序的作用提供了热力学和微观支持。简要讨论了可能的传导机制。

Powder X-ray diffractograms of the substituted LiKSO4 compounds indicate the presence of pure LiKSO4, pure Y2(SO4)3, and new peaks not attributable to either component.
