  • Publication number: 20160013469
    Abstract: An electronic device having a novel structure, specifically, an electronic device having a novel structure that can be changed into various appearances is provided. Specifically, after an active material layer is formed on one or both surfaces of a current collector, the active material layer in a bent region is partly removed. The removed region of the active material layer can be in a linear shape, a dot shape, or a matrix shape, for example. After the active material layer is formed on one or both surfaces of the current collector, laser processing for removing part of the active material layer in an irradiation region is performed using laser light or the like. On the region where the surface of the current collector is exposed, the active material layer is not provided, and this region is a region that does not function as a battery. Owing to this region, a secondary battery with a wide movable region can be achieved.

  • Publication number: 20150333360
    Abstract: In the case where a film, which has lower strength than a metal can, is used as an exterior body of a secondary battery, a current collector provided in a region surrounded by the exterior body, an active material layer provided on a surface of the current collector, or the like might be damaged when force is externally applied to the secondary battery. A secondary battery that is durable even when force is externally applied thereto is provided. A region that is easily partly bent and a region that is not easily partly bent owing to a protective material provided in the region are intentionally formed to obtain the durable secondary battery.

  • Publication number: 20150299371
    Abstract: The present invention is a method for decomposing a polymer material by chemically decomposing a polymer material containing a first monomer and a second monomer in a mixture of the polymer material with the first monomer or a derivative of the first monomer to produce a chemical raw material. A relationship between a proportion of number of molecules of the second monomer to number of molecules of the first monomer in a reaction system for decomposing the polymer material and the molecular weight of the chemical raw material produced in the reaction system is acquired in advance (S101). Subsequently, an addition mount of the derivative of the first monomer to be added to the polymer material is determined based on the above relationship (S102). The first monomer in the addition amount determined is then mixed with the polymer material (S103).

  • Publication number: 20150147626
    Abstract: To provide a power storage unit having a structure which is unlikely to break down by change in shape, such as bending. An electrode plate is covered with a sheet of an insulator which is folded in two. The sheet is preferably processed into a bag-like shape or an envelope-like shape by bonding overlapping portions of the sheet in the periphery of the electrode plate. The electrode plate and the sheet are fixed to an exterior body. In the case where the shape of the exterior body is changed by bending or the like, the electrode plate and the sheet can slide together in the exterior body. Thus, stress on the electrode plate due to bending can be relieved.
