Abstract
A lithium-ion rechargeable battery (1) provided with: a battery unit (100) including a metal substrate (10) and a battery part (20) configured by laminating thin films on the substrate (10); and a shell (200) provided on the surface of the substrate (10), on which the battery part (20) is formed, to seal the substrate (10) and the battery unit (100). The shell (200) includes a laminated film (30) formed by laminating a metal layer (33) and various types of resin layers. Consequently, the thickness of the thin-film type lithium-ion rechargeable battery including a solid electrolyte is reduced.

1-5. (canceled)
A lithium-ion rechargeable battery comprising:
- a battery part including a positive electrode layer containing a positive-electrode active material, a negative electrode layer containing a negative-electrode active material, and a solid electrolyte layer containing an inorganic solid electrolyte having lithium-ion conductivity, the solid electrolyte layer being provided between the positive electrode layer and the negative electrode layer;
- a substrate on one surface of which the battery part is placed;
- and
- a laminated film including a metal layer and a resin layer laminated on the metal layer that is disposed to face the one surface of the substrate, the laminated film sealing the battery part with the substrate in a state in which the metal layer and the battery part are brought into conduction.
A lithium-ion rechargeable battery comprising:
- a battery part including:
- a positive electrode layer containing a positive-electrode active material;
- a negative electrode layer containing a negative-electrode active material;
- and a solid electrolyte layer containing an inorganic solid electrolyte having lithium-ion conductivity, the solid electrolyte layer being provided between the positive electrode layer and the negative electrode layer;
- and
- a sealing part including:
- a substrate on one surface of which the battery part is placed, the substrate being integrated with the battery part;
- and a laminated film formed by laminating a metal layer and a resin layer, the sealing part sealing the battery part with the substrate by holding the battery part with the substrate in a state in which the metal layer and the battery part are brought into conduction.
