摘要：
The present invention relates to an anode for a lithium secondary battery, a method for manufacturing the anode for a lithium secondary battery, and a lithium secondary battery comprising the anode, the lithium secondary battery having a double layer structure according to a specific composition, and also having an adjustable thickness range so as to have the advantage of allowing rapid charging of an electrode to which a high Si particle content is applied as a single-layer active material, and, simultaneously, resolving problems of surface deterioration, uniformity during pre-lithiation, and lifespan characteristics, which are the disadvantages resulting from having same.
