Beschreibung
Zusammenfassung:	A method for producing a film-type anode material for a lithium battery is provided to absorb internal stress caused by swelling, to reinforce structural stability, and to impart excellent cycle characteristics to a lithium battery. A method for producing a film-type anode material for a lithium battery by stacking an anode material(2) on an anode substrate(1) in the form of units in a pattern in which the units are spaced and separated from each other, comprises the steps of: stacking a lower film(3) on the anode substrate to form a separator between the anode substrate and the anode material; and stacking the anode material in the form of units in a pattern wherein the units are spaced and separated from each other, wherein the lower film is stacked on the anode substrate in the form of units in a pattern wherein the units are spaced and separated from each other, and the anode material is stacked on the patterned lower film.
