Abstract
The present invention relates to a method for producing lithium hydroxide and lithium carbonate, wherein the lithium hydroxide and the lithium carbonate can be produced by a series of steps of: performing bipolar electrodialysis of a lithium-containing solution from which divalent ion impurities have been removed; concentrating lithium in the lithium-containing solution and at the same time, converting the lithium to lithium hydroxide; and carbonating the lithium hydroxide to obtain lithium carbonate.
