摘要： 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.
