    摘要: Disclosed herein is a lithium secondary battery having improved life characteristics by removal of metal ion impurities incorporated during an assembly process of the battery via a cation exchange process, thereby preventing electrodeposition of the metal ions on an anode, through the addition of a cation exchange material, containing cations selected from the group consisting of lithium, sodium, ammonium and any combination thereof, to an electrode and/or a surface of a separator.
