A thin pouch battery, which is used as a power source of a portable electronic apparatus, a portable electronic terminal, or the like, includes protrusions, into which an electrode group is inserted, formed in both a laminate film on the upper side and a laminate film on the lower side. Then, concentrically concave and convex wave shapes (concentric crest ridges or trough furrows) are formed on the top surface of each of the protrusions such that the protrusion can extend or shrink in any direction, or the protrusion has a side surface that is gradually inclined and a wave shape is formed on the side surface of the protrusion.

Flexible battery

There is provided a pouch-type battery that includes an exterior packaging member having an accommodating space in which an electrode and an electrolyte are accommodated and which has a curved shape at least in a first direction. The exterior packaging member includes a first film member on which a cup section having the accommodating space inside is provided, a second film member disposed to face the first film member, and a sealing section around the cup section, with which the first and second film members are bonded to each other and the accommodating space is sealed. A top surface of the cup section of the first film member has a curved shape and is provided with a plurality of concave portions or convex portions, and the sealing section has a curved shape in the first direction and is configured of a flat surface on which neither concave portion nor convex portion is provided.

Pouch-type battery and method of manufacturing the same

An object of the present invention is to provide a process for producing an in-mold decorated molded article, which can eliminate the need for deburring after molding and the need for an extra allowance of the molded article. The process includes: clamping a first mold () and a second mold () to hold a decorative film () between the molds; cutting a transfer layer () of the decorative film () in the molds; injecting resin () into the cavity of the mold; cooling the resin (); and opening the molds to remove the in-mold decorated molded article on which the transfer layer () is disposed.
