Abstract

The invention belongs to the technical field of capacitors, and discloses an energy storage film capacitor which comprises a containing box, a sealing cover, a capacitor roll, a first tab, a second tab, a first conducting strip, a second conducting strip, a first wire and a second wire. According to the energy storage film capacitor, the first polypropylene composite film and the second polypropylene composite film are arranged, and the first polypropylene composite film and the second polypropylene composite film are axially rolled in parallel in the same direction to form a capacitor roll. A first empty surface is arranged in a first polypropylene base film, and a second empty surface is arranged in a second polypropylene base film. The surface connection between the second tab and the second metal layer is realized, and the surface connection between the first tab and the first metal layer is realized. The connection performance is improved, and then the charging and discharging capability of the whole energy storage film capacitor is improved.

Description

technical field [0001] The invention belongs to the technical field of capacitors, and particularly relates to an energy storage film capacitor. Background technique [0002] Thin-film capacitors refer to capacitors formed by thin films as dielectrics. Existing film capacitors generally form a first composite film and a second composite film by plating a metal layer on the film, and then use the first composite film and the second composite film to roll parallel to the same axis to form a capacitor roll. In order to allow the first tabs to be drawn from the first composite film, the first tabs are generally formed by placing wires at any position during the roll of the first composite film and then pulling the wires out. In order to allow the second tab to be drawn from the second composite film, the second tab is generally formed by placing a wire at any position during the reeling of the second composite film and then pulling the wire out. [0003] However, in this way o...
