Abstract
Official abstract text for this publication.
A power storage device includes a positive electrode part including a first metallic foil layer and a positive electrode active material layer partially laminated on one surface of the first metallic foil layer, a negative electrode part including a second metallic foil layer and a negative electrode active material layer partially laminated on one surface of the second metallic foil layer, and a separator arranged between the positive electrode part and the negative electrode part. The positive electrode active material layer is arranged between the first metallic foil layer and the separator, and the negative electrode active material layer is arranged between the second metallic foil layer and the separator. The peripheral regions of the one surfaces of the first and second metallic foil layers in which the positive and negative electrode active material layers are not formed are joined via a peripheral sealing layer containing a thermoplastic resin.
First claim
Opening claim text (preview).
The invention claimed is: 1. A production method of a thin power storage device, comprising: a step of preparing a positive electrode side sheet body including a first metallic foil layer, a positive electrode active material layer laminated on a partial region of one surface of the first metallic foil layer, and a first thermoplastic resin layer provided at a peripheral portion of the one surface of the first metallic foil layer on which the positive electrode active material layer is not formed; a step of preparing a negative electrode side sheet body including a second metallic foil layer, a negative electrode active material layer laminated on a partial region of one surface of the second metallic foil layer, and a second thermoplastic resin layer provided at a peripheral portion of the one surface of the second metallic foil layer on which the negative electrode active material layer is not formed; a step of preparing a separator; and a step of heat-sealing the first thermoplastic resin layer of the positive electrode side sheet body and the second thermoplastic resin layer of the negative electrode side sheet body in a state in which the positive electrode side sheet body and the negative electrode side sheet body are in contact with each other via respective thermoplastic resin layers and the separator is sandwiched by and between the positive electrode active material layer and the negative electrode active material layer. 2. The production method of a thin power storage device as recited in claim 1 , wherein the first thermoplastic resin layer is formed by a thermoplastic resin unstretched film and the second thermoplastic resin layer is formed by a thermoplastic resin unstretched film.
