Embodiment 1

[0146] Coating a chemical conversion treatment solution containing polyacrylic acid, phosphoric acid, and compounds of chromium and fluorine on both sides of an aluminum foil with a thickness of 30 μm, and drying at 150°C to achieve a chromium adhesion amount of 3 mg / m 2 .

[0147] On one side of the aluminum foil (metal foil layer) that has undergone the chemical conversion treatment, a polyester-urethane adhesive is applied. Thereafter, a biaxially stretched polyethylene terephthalate (PET) film (acid-resistant layer) having a thickness of 6 μm was bonded to the polyester-urethane adhesive-coated surface.

[0148] Next, 100 parts by mass of maleic acid-modified polypropylene (melting point 90° C., maleic anhydride content 0.3 mass %), 1 part by mass of toluene diisocyanate, Resin composition of 0.1 parts by mass of silica (anti-blocking agent) and 0.2 parts by mass of 5-butyloxazole-2,4-dione (lubricant), followed by curing by heating at 80°C In 1 day, an insulating layer ...

Embodiment 2

[0151] Coating a chemical conversion treatment solution containing polyacrylic acid, phosphoric acid, and compounds of chromium and fluorine on both sides of an aluminum foil with a thickness of 25 μm, and drying at 150°C to achieve a chromium adhesion amount of 3 mg / m 2 .

[0152] On one side of the aluminum foil (metal foil layer) that has undergone the chemical conversion treatment, a polyester-urethane adhesive is applied. Thereafter, a biaxially stretched polyethylene terephthalate (PET) film (acid-resistant layer) having a thickness of 2 μm was bonded to the polyester-urethane adhesive-coated surface.

[0153] Next, 100 parts by mass of maleic acid-modified polypropylene (melting point 90° C., maleic anhydride content 0.3 mass %), 1 part by mass of toluene diisocyanate, A resin composition of 0.1 parts by mass of silica (anti-blocking agent) and 0.2 parts by mass of 5-butyloxazole-2,4-dione (lubricant) was cured by heating at 80° C. for 1 day to form a thickness of 3 μm...

Embodiment 3

[0156]Instead, use a laminated film of a biaxially stretched polyethylene terephthalate (PET) film with a thickness of 6 μm / a biaxially stretched polyamide film with a thickness of 20 μm (the polyamide film is placed on the inside (side of the aluminum foil)) A biaxially stretched PET film with a thickness of 6 μm is coated with 20 parts by mass of epoxy melamine resin, 0.3 parts by mass of silicon dioxide (anti-blocking agent), 0.2 parts by mass of polyethylene wax (lubricant), and 64 parts by mass of toluene (solvent). Parts by mass and 16 parts by mass of MEK (solvent) were used instead of the coating solution containing maleic acid-modified polypropylene, and then heated at 200°C for 1 minute to thermally cure and form epoxymelamine with a thickness of 3 μm. The thermally cured layer of the resin was obtained in the same manner as in Example 1 except that image 3 The outer packaging materials for the electrical storage equipment shown.

Abstract

A package for a power storage device includes a metal foil layer, an insulation layer laminated on at least center portion of one surface of the metal foil layer, and a heat-sealable resin layer arranged one surface of the metal foil layer or a region corresponding to a periphery of the one surface of the metal foil layer. With this, thinning, weight saving, and shortening of the production time can be attained.

Description

technical field [0001] The present invention relates to a thin and lightweight outer packaging material used for a mobile storage device such as a smartphone or a tablet computer, and an electrical storage device packaged with the outer packaging material. Batteries and capacitors for equipment; batteries and capacitors for hybrid vehicles, electric vehicles, wind power generation, solar power generation, nighttime power storage, etc. [0002] In addition, in this specification, the term "aluminum" is used in the meaning including aluminum and its alloy. Background technique [0003] In recent years, with the reduction in thickness and weight of mobile electronic devices such as smartphones and tablet terminals, lithium ion secondary batteries, lithium polymer secondary batteries, lithium ion capacitors, and electric double layer As the outer packaging material of electric storage devices such as capacitors, a laminate consisting of heat-resistant resin layer / adhesive layer...
