摘要

用真空重量法研究了锂盐溶液在40、50、60和70℃下形成的LiClO4、LiSO3CF3、LiN(SO2CF3)2、LiBF4和LiPF6与亚砜溶剂配合物的组成。研究表明，溶剂化物配合物的组成是由它们的形成温度和锂盐阴离子的性质决定的。溶剂化物配合物的比离子电导率在0.4-1.8×10-3 S/cm范围内，阳离子电导率在0.3-0.8×10-3 S/cm范围内。该磺胺基溶剂化物配合物具有较高的热稳定性（>320℃），并能在较宽的温度范围内以液态存在。

Solvate Complexes of Lithium Salts with Sulfolane as Electrolytes for Advanced Energy Storage Devices

The composition of solvate complexes of LiClO₄, LiSO₃CF₃, LiN(SO₂CF₃)₂, LiBF₄, and LiPF₆ with sulfolane formed from lithium salt solutions at 40, 50, 60, and 70°C has been studied by vacuum gravimetry method. It has been shown that the composition of the solvate complexes is determined by the temperature of their formation and the nature of the lithium salt anion. The specific ion conductivity of the solvate complexes has been in the range of 0.4–1.8×10^–3 S/cm, and the cationic conductivity has been in the range of 0.3–0.8×10^–3 S/cm. The sulfolane-based solvate complexes have exhibited high thermal stability (>320°C) and have existed in the liquid state over a wide temperature range.

期刊介绍： Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
