摘要： Provided is a method for recovering lithium from waste lithium-ion batteries that can recover lithium at a high recovery rate and enables resource circulation. In the method for recovering lithium from waste lithium-ion batteries, active material powder obtained by pre-processing waste lithium-ion batteries is dissolved in a mineral acid, an alkali metal hydroxide is added to the obtained acid solution, and then at least one metal excluding lithium, out of the metals contained in the active material powder, is separated by solvent extraction to obtain a first alkali metal salt aqueous solution. The first alkali metal salt aqueous solution is electrolyzed using an ion exchange membrane. An alkali metal hydroxide aqueous solution obtained by the electrolysis is used as the alkali metal hydroxide to be added to the acid solution, or used for the solvent extraction. An acid obtained by the electrolysis is used as the mineral acid.
