Abstract: The present invention relates to an electrode composite film comprising: a binder having a three-dimensional fiber network structure; and an electrode active material accommodated within the fiber network structure, wherein the electrode composite film has an R value, defined by the density and tensile strength of the electrode composite film, in the range of 5.0 to 10.0. By enhancing the sheet formation completeness of the electrode composite film, the R value can meet the range, thereby providing an electrode composite film with excellent mechanical strength, superior surface appearance, and stable performance in the lamination process with the current collector.
