摘要： Provided is a method for producing an active material for a lithium secondary battery to enable efficient removal of iron impurities, which would become a problem in production of an active material for a lithium secondary battery, and attain a high quality. The method includes removing iron impurities in an active material for a lithium secondary battery by means of magnetic force. With this method, use of a magnetic force-generating device within a recess portion, which composes at least one part of the recess portion, enables efficient removal of only iron impurities. Thus, it is expected that a voltage drop caused by dissolution of iron compounds, i.e. impurities in a positive electrode, and their migration to a negative electrode in a battery, and decreases in charge and discharge efficiencies and a voltage drop owing to precipitation of lithium can be suppressed.
