Abstract:
A method is provided for producing a separator by cutting a laminated porous film. The laminated porous film includes a porous base material layer containing polyolefin as a main component and a filler layer containing inorganic particles as a main component. The filler layer is provided on one surface of the porous base material layer; and a resin layer containing resin particles as a main component is provided on the other surface of the porous base material layer. The method includes a step of cutting, using a slit blade, the laminated porous film from the one surface on which the filler layer is provided.
Abstract:
The present invention relates to a composite film and a method of fabricating the same. The present invention provides a highly flexible and pliable composite film capable of preventing interlayer deformation or interlayer exfoliation based on a difference between thermal expansion coefficients. The composite film comprises a first protection layer; and a fabric layer adhered onto the first protection layer via an adhesive layer.
Abstract:
Provided is a molding packaging material that can have an increased use life, can suppress a decrease over time in inter-layer lamination strength, and can have superior molding properties in extrusion molding, draw forming, and the like. The laminate molding packaging material contains: an outside substrate layer (2) comprising a heat resistant resin; an inside sealant layer (3) comprising a thermoplastic resin; and a metal foil provided between the two layers as a barrier layer (4). A matte coat layer (6) comprising a heat resistant resin coating film containing a dispersion of inorganic or organic solid microparticles is formed on the outer surface of the outside substrate layer (2), and the gloss value of the surface thereof is suppressed to no greater than 30%.
Abstract:
A production device 100 for a packaged electrode 20, to which a separator welding device is applied, includes joining heads 301 having joining tips 302 and 303 that join a pair of separators 30 to each other and holding units 304 that fasten the pair of separators. After the joining heads 301 are moved closer to each other with respect to the separators, and the separators are fastened by the holding units 304, the pair of separators is joined to each other by the joining tips 301. Meanwhile, after the joining heads 301 are separated from each other with respect to the separators, and the joining tips are separated from the pair of separators, the separators are released from fastening by the holding units 304.
