Embodiment

[0012] According to the molar ratio of anhydrous lithium chloride:anhydrous gallium trichloride=1:1, weigh 42.4g of lithium chloride and 176.07g of gallium trichloride respectively, put them into a closed container, then put them into an oven, and heat at 200°C 3h, the obtained transparent solution was cooled to room temperature to obtain the synthesized lithium tetrachlorogallate.

[0013] Lithium tetrachlorogallate and thionyl chloride (SOCl 2 ) together to prepare an electrolyte solution, the molar concentration of lithium tetrachlorogallate is 0.5mol / L.

[0014] 1.5M LiAlCl 4 / SOCl 2 Electrolyte and 0.5M LiGaCl 4 / SOCl 2 The electrolyte solution is injected into the square lithium / thionyl chloride battery respectively, the battery is welded and sealed, and then the battery is pulse-discharged, and the battery using the electrolyte salt of lithium tetrachlorogallate: the working voltage of the 0.1C rate constant value discharge is changed from 3.51V Increased to 3.54V,...

Abstract

The invention discloses an electrolyte salt of a lithium / thionyl chloride battery and a preparation method thereof, and the electrolyte salt is characterized in that the electrolyte salt is synthetic lithium tetrachlorogallate (LiGaCl4), and the molar concentration range of the lithium tetrachlorogallate in the electrolyte is 0.5 mol / L to 1.5 mol / L. The lithium tetrachlorogallate is synthesized by fusing anhydrous lithium chloride (LiCl) and anhydrous gallium trichloride (GaCl3) in a dry reaction vessel. The anhydrous lithium chloride and the anhydrous gallium trichloride require drying treatment.

Description

technical field [0001] The invention relates to an electrolyte salt of a lithium / thionyl chloride battery and a preparation method thereof. Background technique [0002] Lithium / thionyl chloride battery is the battery with the highest working voltage (3.6V) and the highest actual output specific energy (590W·h / Kg) in the practical battery series, and is widely used in civil and military aerospace fields. With the development of battery technology, lithium / thionyl chloride batteries are used in space and military applications, such as space platforms such as rocket upper stages and returnable satellites, and underwater weapon platforms such as torpedoes and mines. High-current pulse discharges are required. [0003] At present, the electrolyte salt of lithium / thionyl chloride battery uses lithium tetrachloroaluminate (LiAlCl 4 ), however, the internal resistance of the battery is still large during pulse discharge, resulting in low pulse discharge voltage, so higher performa...
