CONDUCTIVE FILM, FABRICATION METHOD OF CONDUCTIVE FILM, AND LITHIUM-ION BATTERY (LIB)

A conductive film, a fabrication method of the conductive film, and a lithium-ion battery (LIB) are provided. The fabrication method includes: S: selecting a support layer, and plating a first metal layer on upper and lower surfaces of the support layer, respectively; S: compounding a first film on a surface of one of the first metal layers, and compounding a second film on a surface of the other one of the first metal layers; S: compounding a third film on surfaces of the first film and the second film, and etching a plurality of circular holes penetrating through the third film and the second film; S: plating a second metal layer on an outer surface of the third film and an inner wall of the circular hole; S: fabricating a composite film; and S: plating a third metal layer on upper and lower surfaces of the composite film.
