A flat battery basically comprises a battery body, a plate-shaped member and an elastic member. The battery body includes a power generation unit and a case member encasing and sealing the power generation unit therein. The plate-shaped member is configured to be disposed between an outer periphery portion of the battery body and an outer periphery portion of an adjacent battery body stacked that is to be stacked on the battery body. The elastic member joins the battery body and the plate-shaped member to connect the battery body and the plate-shaped member, and covers at least part of the plate-shaped member. The plate-shaped member includes an exposed part which is exposed from part of an end surface of the elastic member which covers the plate-shaped member in a thickness direction of the battery body.

Flat battery and method for producing flat battery

A compressed air is ejected from air ejector ports () to between a mold surface defining cavity () of mold () and a surface of a hot melt resin layer after starting to fill or inject the hot melt resin material into cavity () and before a temperature of the hot melt resin material becomes equal to or lower than a softening point thereof. Recesses (Q) are formed by positively generating a 'sink mark' on a surface of edge protector () by ejection of the compressed air, and at the same time, gap (G) is formed between the surface of edge protector () and the mold surface. As a result, when bead-shaped edge protector () is integrally formed in long-side heat-fused portions () of laminated-film exterior package case () by using a thermoplastic hot melt resin material, mold releasability of the molded edge protector from the mold can be enhanced.

Fabrication method for laminated-type secondary battery

A gas diffusion electrode material of the present invention includes: a porous body () formed of continuous and discontinuous polytetrafluoroethylene microfibers () and having three-dimensionally continuous micropores (); and a conductive material () supported on the porous body (). Moreover, a density of the polytetrafluoroethylene microfiber () is lower in a surface region (A) of a cross section of the porous body () than in an intermediate region (B) of the cross section. In accordance with the present invention, the polytetrafluoroethylene having the predetermined three-dimensional structure is used, and so on. Therefore, it is possible to provide a gas diffusion electrode material excellent in power generation characteristics and durability.

Gas diffusion electrode material and production method thereof

Disclosed is a foam-molded member having a skin with which peeling or floating does not occur when the skin is wrapped. Also disclosed is a method of manufacturing the foam-molded member having a skin. A foam-molded member having a skin, such as a door trim, includes a core, a skin, foam and a fixing member. The core can be folded at a folding portion, and the skin faces the core. The foam is filled in a space between the core and the skin. The fixing member fixes the core that is integrally formed with the skin and the foam and is folded at the folding portion. The core is divided into a body portion and an extension portion, with the folding portion serving as a boundary. The extension portion folded at the folding portion is fixed to the body portion by the fixing member.
