Abstract
Official abstract text for this publication.
Disclosed is a process for one-step preparing electrolyte used for lithium-iron(II) disulfide batteries. The process includes the following steps of: adding iodine-containing precursors into an organic solvent in an inert atmosphere, homogeneously stirring, then adding lithium-containing precursors, stirring and reacting, separating solids to obtain an electrolyte used for lithium-iron(II) disulfide batteries. The process involves one-step synthesizing electrolyte used for lithium-iron(II) disulfide batteries. The whole procedures do not introduce water and have a lower cost. The lithium-iron(II) disulfide batteries prepared by using the electrolyte prepared by the process of the present invention have better properties.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for one-step preparing electrolyte used for a lithium-iron(II) disulfide battery, comprising steps of: adding anhydrous aluminum triiodide at 40-70° C. into an organic solvent in an inert atmosphere, stirring for 0.5-2 h, then adding anhydrous lithium hydroxide, stirring and reacting for 6-8 h, centrifuging and filtering to obtain an electrolyte used for lithium-iron(II) disulfide batteries, wherein the anhydrous aluminum triiodide and anhydrous lithium hydroxide have a molar ratio of 1:(3.6-10). 2. The process according to claim 1 , wherein an inert gas in the inert atmosphere is one selected from the group consisting of nitrogen and argon. 3. The process according to claim 1 , wherein the inert atmosphere has a gas purity of greater than or equal to 99.99%, a moisture content of less than or equal to 10 ppm, and an oxygen content of less than or equal to 0.5 ppm. 4. The process according to claim 1 , wherein the organic solvent is dehydrated before use. 5. The process according to claim 4 , wherein the dehydrated organic solvent has a moisture content of less than or equal to 10 ppm. 6. The process according to claim 4 , wherein the organic solvent is dehydrated by using molecular sieves. 7. The process wherein according to claim 1 , wherein the organic solvent is a mixed solvent of glycol dimethyl ether and 1,3-dioxolane. 8. The process according to claim 1 , wherein the organic solvent is a mixed solvent of 25-45 wt. % of glycol dimethyl ether and 55-75 wt. % of 1,3-dioxolane.
