    Abstract: A lithium-ion rechargeable battery 1 includes a battery part 10 which performs charging and discharging using lithium ions, and a shell 30 for housing the battery part 10 in the interior thereof. The shell 30 is constituted by thermally adhering a first laminated film 31 which includes a first metal layer 313 and a first thermo-adhesive resin layer 315, a second laminated film 32 which includes a second metal layer 323 and a second thermo-adhesive resin layer 325 by thermally adhering the first thermo-adhesive resin layer 315 and the second thermo-adhesive resin layer 325. Moreover, the positive electrode side of the battery part 10 is electrically connected to the first metal layer 313 of the first laminated film 31, and the negative electrode side of the battery part 10 is electrically connected to the second metal layer 323 of the second laminated film 32.

    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.

    Abstract: A lithium-ion rechargeable battery 1 includes: a stainless-steel substrate 10; a negative electrode layer 20 that contains a negative-electrode active material and is laminated on the substrate 10; a solid electrolyte layer that contains an inorganic solid electrolyte having lithium-ion conductivity and is laminated on the negative electrode layer 20; a positive electrode layer 40 that contains a positive-electrode active material and is laminated on the solid electrolyte layer 30; and a positive electrode collector layer 50 that is composed of titanium and is laminated on the positive electrode layer 40. The boundary portion of the solid electrolyte layer 30 and the positive electrode layer 40 in the lithium-ion rechargeable battery 1 is provided with a mixture layer 70 in which the positive-electrode active material and the inorganic solid electrolyte are mixed. These increase the discharge capacity of the all-solid lithium-ion rechargeable battery.
