Recovery of Lithium Carbonate from Basic Aqueous Lithium Containing Solutions

原文（中国語）

A more efficient and lower waste liquid-phase method for recovering lithium carbonate suitable for high-performance lithium applications from recycled lithium-ion battery and other sources of lithium hydroxide including aqueous solutions is described. The method uses carbon dioxide gas to directly form lithium carbonate from a lithium hydroxide including solution, thus eliminating the need for conventional acid pre-treatment and reducing the need for subsequent sodium carbonate addition.
