Abstract

The invention belongs to the technical field of lithium primary batteries and discloses a preparation method for electrolyte used for a lithium-ferrous disulfide battery. The preparation method for the electrolyte used for the lithium-ferrous disulfide battery comprises the following steps of adding anhydrous aluminum triiodide into an organic solvent in an inert atmosphere at a temperature of 40-70 DEG C for stirring for 0.5-2 hours, then adding anhydrous lithium hydroxide for stirring and reacting for 6-8 hours, and centrifuging and filtering to obtain the electrolyte used for the lithium-ferrous disulfide battery. The preparation method adopts a one-step method for synthesis of the electrolyte used for the lithium-ferrous disulfide battery; water content is not introduced in the whole preparation process, the cost is relatively low, and the lithium-ferrous disulfide battery prepared from the electrolyte obtained by the preparation method is good in performance.

Description

technical field

[0001] The invention belongs to the technical field of lithium primary batteries, and relates to an electrolyte solution for a lithium-ferrous disulfide battery, in particular to a preparation method for one-step synthesis of the electrolyte solution for a lithium-ferrous disulfide battery. Background technique

[0002] Lithium primary batteries are divided into high-voltage and low-voltage batteries according to the open circuit voltage. The open circuit voltage ≥ 3.0V is a high-voltage lithium primary battery, such as lithium-thionyl chloride (Li / SOCl 2 ) batteries, lithium-manganese dioxide (Li / MnO 2 ) battery and lithium-carbon lithium fluoride (Li / CF X ) battery; open circuit voltage <3.0V is a low-voltage lithium primary battery, such as lithium-iron disulfide (Li / FeS 2 )Battery.

[0003] Due to Li / FeS 2 The battery is a low-voltage lithium primary battery, and its working voltage platform is 1.5V, so it is comparable to the alkaline manganese (Z...
