    • Provided is a safe and efficient method for producing lithium metal which facilitates efficient production of anhydrous lithium chloride without corrosion of the system materials by chlorine gas or molten lithium carbonate, and which allows production of lithium metal by molten salt electrolysis of the produced anhydrous lithium chloride as a raw material. The method includes the steps of (A) contacting and reacting lithium carbonate and chlorine gas in a dry process to produce anhydrous lithium chloride, and (B) subjecting the raw material for electrolysis containing the anhydrous lithium chloride to molten salt electrolysis under such conditions as to produce lithium metal, wherein the chlorine gas generated by the molten salt electrolysis in step (B) is used as the chlorine gas in step (A) to continuously perform steps (A) and (B).
    • 提供了一种安全有效的生产锂金属的方法,其有助于无氯氯化物的有效生产,而不会由于氯气或熔融碳酸锂而使系统材料腐蚀,并且通过熔融盐电解生产无机氯化锂的锂金属 作为原料。 该方法包括以下步骤:(A)在干法中使碳酸锂和氯气接触并反应生成无水氯化锂;(B)将含有无水氯化锂的电解原料进行熔融盐电解, 为了生产锂金属,其中在步骤(B)中通过熔融盐电解产生的氯气用作步骤(A)中的氯气,以连续进行步骤(A)和(B)。
