Abstract: PURPOSE: An anode film for a lithium secondary battery is provided to improve cycle properties by preventing the expansion and reduction of a silicon volume during recharging and discharging process, and to improve the battery service life owing to its chemical and mechanical stability. CONSTITUTION: The anode film for a lithium secondary battery comprises a current collector and an anode active material layer formed on the upper side of the current collector, wherein the anode active material layer is comprised of a multiple layered film where a metal layer that is non-reactive to lithium but reactive to silicon, and a silicon layer are alternately layered. The anode film for a lithium secondary battery is produced by the steps of: (a) forming a film of a metal layer that is non-reactive to lithium but reactive to silicon, onto the current collector by deposition; (b) forming a film of a silicon layer over the metal layer; and (c) repeating the (a) or (b) step at least once to form a multiple layered film.
