CONDUCTIVE FILM, FABRICATION METHOD OF CONDUCTIVE THIN FILM, AND LITHIUM-ION BATTERY

The present disclosure discloses a conductive film, a fabrication method of the conductive film, and a lithium-ion battery (LIB), and relates to the technical field of conductive film fabrication. The fabrication method includes the following steps: S10: selecting a support layer, and plating a first metal layer on upper and lower surfaces of the support layer, respectively; S20: 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; S30: compounding a third film on surfaces of the first film and the second film by a film compounding technology, and etching a plurality of circular holes penetrating through the third film and the second film; S40: plating a second metal layer on an outer surface of the third film and an inner wall of the circular hole; S50: fabricating a composite film; and S60: plating a third metal layer on upper and lower surfaces of the composite film by a vacuum coating technology, and rolling to obtain the conductive film. The present disclosure has the beneficial effects of preventing a battery from overheating and burning, and improving the electrical conductivity and tensile strength of the conductive film.
