Abstract:
1. A method for producing a lithium secondary battery comprising a negative electrode having a negative electrode active material layer containing a carbonaceous negative electrode active material and a first binder on a surface of a negative electrode current collector, and a protective layer containing an insulating filler and a second binder on the negative electrode active material layer, the method comprising: coating and compressing a composition for forming a negative electrode active material layer containing the carbonaceous negative electrode active material onto the negative electrode current collector, to prepare a negative electrode raw material on which is formed the negative electrode active material layer, and configuring the lithium secondary battery so that an initial capacity ratio (N/P) of an initial capacity of the negative electrode raw material (N [mAh/cm wherein a ratio (T
