Abstract
Disclosed are a silicon thin film anode for a lithium secondary battery having enhanced cycle characteristics and capacity and a preparation method thereof. A preparation method for a silicon thin film anode for a lithium secondary battery, comprises: preparing a collector including a metal; forming an anode active material layer including a silicon on the collector; forming one or more interface stabilizing layer, by annealing the collector and the anode active material layer under one of an inert atmosphere, a reduced atmosphere, and a vacuum atmosphere to react a metallic component of at least one of the collector and the anode active material layer with a silicon component of the anode active material layer at an interface therebetween; and forming a carbon coating layer on the anode active material layer by performing an annealing process in a hydrocarbon atmosphere.
