A Method For Preparing Lithium Carbonate By Recycling Lithium From Used Anode Of Lithium Ion Seondary Battery |
| abstract |
The present invention relates to a method for producing lithium carbonate by recovering lithium from a waste cathode material of a lithium ion secondary battery. (B) separating the filtrate obtained in step (a) by hydrolysis using sodium carbonate to obtain a lithium aqueous solution and a carbonate cake; and (c) adding an alkali compound to the lithium aqueous solution obtained in step (b) to remove impurities; and (d) adding sodium carbonate or carbon dioxide gas to the impurity-removed lithium solution obtained in step (c) And synthesizing the signal. According to the present invention, lithium carbonate can be recovered through acid leaching from the waste cathode material of the lithium ion secondary battery, thereby synthesizing lithium carbonate which can be reused in the production of the cathode active material. According to the present invention, lithium can be efficiently recovered by a more economical and simplified process than conventional processes (such as solvent extraction), and thus lithium carbonate can be synthesized by a low-cost and high-efficiency process. |
