NOVELTY - The battery has a positive electrode active material layer formed in a predetermined area of a side of a positive electrode metal foil (5). A negative electrode active material layer is formed in a predetermined area of a side of a negative electrode metal foil (6). A zigzag structure is formed such that a negative electrode provided by a negative electrode non-application part area, in which the negative electrode active material layer is not formed, is folded through a sheet-like separator (3), in a position of a positive electrode non-application part area.    USE - Laminate-type battery e.g. large-sized and high capacity closed-type battery such as non-aqueous secondary lithium ion battery, for use as a power supply of portable electronic devices e.g. mobile telephone and notebook-type personal computer, and an electric vehicle. Can also be used for an electric tool, a motor vehicle and a bicycle.    ADVANTAGE - The positive electrode active material layer is formed in the predetermined area of the side of the positive electrode metal foil, so that packing density of the positive electrode active material can be improved. The battery shortens conduction path of ion in the separator, so that charging/discharging cycle property and high-temperature-storage property of the battery can be improved. The battery utilizes a non-aqueous electrolyte, so that use safety of the battery can be improved. The battery forms a clearance gap between particles to prevent short circuit resulting from generation of lithium dendrite. The battery reduces disconnection process of the electrode and the separator, so that risk of a foreign material mixing with inner side of the battery can be decreased.    DETAILED DESCRIPTION - The positive electrode metal foil is an aluminum foil. A negative electrode metal foil is a copper foil. The separator consists of polyolefin such as polyethylene, polypropylene and ethylene propylene copolymer, polyester such as polyethylene terephthalate and co-polyester.
