Title:
A METHOD AND APPARATUS FOR PREPARING HIGH-PURITY METALLIC LITHIUM BASED ON LITHIUM-ION SOLID-LIQUID DUAL ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2024/078526
Kind Code:
A1
Abstract:
A method and apparatus are disclosed for producing high-purity metallic lithium based on a lithium-ion solid-liquid dual electrolyte. The method allows for the direct production of high-purity metallic lithium from low-purity LiCl by using a one-step process. Based on the disclosed techniques, the difficulty of obtaining low-purity LiCl from salt lakes is relatively low, the cost is low, and the environmental impact is minimal.
