Embodiment 1

[0230] As the substrate layer, polyethylene terephthalate film (12 μm) / adhesive layer (two-component curing polyurethane adhesive (polyol compound and aromatic isocyanate compound), thickness 3 μm) / biaxial A laminated film in which stretched nylon films (thickness 15 μm) are sequentially laminated. Moreover, the barrier layer which consists of aluminum alloy foil (JIS H4160:1994A8021H-O, thickness 40 micrometers) was prepared. Both surfaces of the barrier layer were subjected to chemical conversion treatment by a method described later to form a barrier layer protective film (thickness: 10 nm). Next, the barrier layer and the substrate layer are laminated by dry lamination. Specifically, a two-component curing polyurethane adhesive (polyol compound and aromatic isocyanate compound) is applied to one surface of the barrier layer protective film formed on the surface of the barrier layer to form an adhesive layer (thickness after curing). 3 μm). Next, after laminating the adh...

Embodiment 2

[0233] As the heat-sealable resin layer, except that the polyethylene film (thickness 40 μm) of Table 1 was used, it was carried out in the same manner as in Example 1 to obtain a substrate layer (polyethylene terephthalate film (12 μm)) / Adhesive layer (3μm) / Biaxially stretched nylon film (15μm) / Adhesive layer (3μm) / Barrier layer protective film (10nm) / Barrier layer (40μm) / Barrier layer protective film (10nm) / Adhesive It is an outer packaging material composed of a laminate formed by sequentially laminating the bonding layer (3μm) / heat-sealable resin layer (40μm).

Embodiment 3

[0235] Except not forming a barrier layer protective film on the surface of the barrier layer, the same operation as in Example 1 was carried out to obtain a substrate layer (polyethylene terephthalate film (12 μm)) / adhesive layer (3 μm) / Biaxially stretched nylon film (15μm) / adhesive layer (3μm) / barrier layer (40μm) / adhesive layer (3μm) / heat-sealable resin layer (35μm) laminated in this order outer packaging materials.

Abstract

Provided is an exterior packaging material which is applied to an all-solid-state battery using a solid electrolyte containing a sulfide solid electrolyte material, the exterior packaging material having a barrier layer in which deterioration is effectively suppressed even when the all-solid-state battery is constrained in a high-pressure state, wherein hydrogen sulfide generated inside the all-solid-state battery can be discharged to the outside. The exterior packaging material for an all-solid-state battery is used for an all-solid-state battery including a sulfide solid electrolyte material, and is composed of a laminate having: at least a substrate layer; a barrier layer; a barrier layer protection film formed on the surface of the barrier layer; and a heat-fusible resin layer in this order from the outside, wherein the amount of hydrogen sulfide permeation through the resin constituting the heat-fusible resin layer is at least 1.0*10<-8> cc*mm / cm<2>*sec*cmHg.

Description

technical field [0001] The present invention relates to an outer packaging material for an all-solid battery, a manufacturing method thereof, and an all-solid battery. Background technique [0002] The known electrolyte is an all-solid battery with a solid electrolyte. The all-solid battery has the advantages of high safety and wide operating temperature range because no organic solvent is used in the battery. [0003] On the other hand, it is known that all solid-state batteries tend to peel off between the solid electrolyte and the negative electrode active material layer or positive electrode active material layer due to the expansion and contraction of the negative electrode or positive electrode associated with charging and discharging, and deterioration of the battery tends to occur. [0004] As a method of suppressing peeling between a solid electrolyte and a negative electrode active material layer or a positive electrode active material layer, a technique of restra...
