  • A process for producing carbon impurity reduced/carbon impurity free lithium sulfide, said carbon impurity reduced/carbon impurity free lithium sulfide, and its use for producing solid-state electrolytes and solid-state batteries
    Publication number: 20260337024
    Abstract: The invention relates to a process for the production of lithium sulfide reduced in carbon impurity or free from carbon impurity, in which lithium sulfate and optionally lithium sulfit, lithium disulfate and/or other lithium sulfur oxides, and carbon impurity containing lithium sulfide are treated with hydrogen gas at temperautres in range from 300 to 600 °C. The invention further relates to a lithium sulfide producible in this manner, the carbon impurity content of which is less than 2.0% by weight, based on the weight of the lithium sulfide. This lithium sulfide is used for the production of battery components, preferably solid electrolytes, and solid-state batteries.
