The invention provides a method for preparing imidodisulfuryl fluoride lithium. The method comprises the following steps: (1) reacting imidodisulfuryl fluoride with antimony trifluoride under a solvent free condition, and distilling to obtain imidodisulfuryl fluoride lithium intermediate; (2) reacting metal lithium with anhydrate low alcohol, and concentrating and drying to obtain anhydrate low alcohol lithium; and (3) reacting the imidodisulfuryl fluoride lithium with lithium alkoxide, concentrating, pulping, filtering and drying to obtain a high-purity imidodisulfuryl fluoride lithium product. The method for preparing the imidodisulfuryl fluoride lithium has the characteristics of low cost, high purity and simple operation, and is suitable for industrial production.
