Definitions
- the present invention relates to a method for joining a lead tab for a polymer battery to a resin film.
- a battery main body composed of a positive electrode film and a negative electrode film is packaged by an outer package.
- the outer package plays the role of maintaining the moisture-proof, barrier properties, sealing properties, insulation properties, etc. of the polymer battery.
- the outer layer has an insulating property and a metal foil mainly composed of aluminum, nickel, etc.
- FIG. 8A shows a cross section of a portion where the lead tab passes through the exterior body, where T is the lead tab, and L is the exterior body made of a laminate.
- the method disclosed in the above-mentioned publication discloses a method of connecting a lead tab to a resin film. Bonding is performed by bonding, and therefore the resin film is a laminated film whose inner layer is used as an adhesive. In other words, the resin film has a multilayer structure containing an adhesive (hot melt adhesive), which complicates the manufacturing process of the resin film, increases the cost, and has a negative effect on the environment. There is.
