Title:
A METHOD AND DEVICE FOR PREPARING HIGH-PURITY LITHIUM HYDROXIDE BASED ON LITHIUM-ION SOLID-STATE ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2024/078386
Kind Code:
A1
Abstract:
A method for preparing lithium hydroxide includes reducing water vapor at a low potential in presence of lithium ions to generate LiOH by using a lithium-containing molten salt as an electrolyte material at an reaction temperature of 150℃-450℃, an electrolysis voltage of 1.5V-3V, and a current density of 1-100 mA/cm2. A solid-state electrolyte is disposed between an anode and a cathode for electrolysis, and the water vapor is introduced at the cathode during the electrolysis.
