Abstract: An object of the present invention is to provide a polycarbonate resin composition which satisfies mechanical properties, flame retardancy, and appearance of molded articles at a higher level. The flame-retardant polycarbonate resin composition of the present disclosure contains, based on 100 parts by weight of a resin component consisting of (A) 40 to 100 parts by weight of a polycarbonate resin (component A) and (B) 60 to 0 parts by weight of a polyester resin (component B), (CI) 0 to 30 parts by weight of a polymer obtained by polymerizing at least one selected from the group consisting of an aromatic vinyl monomer, a vinyl cyanide monomer, and an alkyl (meth) acrylate monomer (component CI), (CII) 1 to 10 parts by weight of an impact modifier other than the component CI (component CII), (D) 1 to 20 parts by weight of phosphazene having 98.5 mol % or more of phosphazene cyclic trimer (component D), and (E) 0.05 to 2 parts by weight of dripping inhibitor (component E).

Abstract: A battery case configured to accommodate one or a plurality of battery cells, and includes a metal plate portion and a resin portion. The metal plate portion is made up of a plurality of metal plates that is part of the battery case. The resin portion that is another part of the battery case connects the metal plates by being interposed between the metal plates. The metal plates include a first metal plate and a second metal plate. The first metal plate includes a first overlapping portion and the second metal plate includes a second overlapping portion, the first overlapping portion and the second overlapping portion being overlapped with each other across the resin portion. The first overlapping portion includes one or more contact protrusions protruding toward the second overlapping portion. The second overlapping portion is in direct contact with the one or more contact protrusions.

Abstract: A cell case includes (i) first and second metal plates constituting a first part of the cell case and placed such that the first and second metal plates are separated from each other (ii) a resin portion provided between the metal plates such that the resin portion connects the first and second metal plates. The first metal plate and the second metal plate include a first overlapped portion and a second overlapped portion, respectively, such that the first overlapped portion and the second overlapped portion overlap with each other via the resin portion. The first overlapped portion includes a hook. The second overlapped portion has an opening. The hook is formed to be caught on the opening to restrict relative displacement between the first metal plate and the second metal plate along a direction where the first metal plate and the second metal plate are separated from each other.
