    摘要： The opening to be sealed in a battery is sealed with an electrical insulating sealant S by placing an electrical insulating sealing material C, including a first sealing material A that is soften by heat applied for sealing and a second sealing material B that is more difficult to soften by the heat applied for sealing than the first sealing material A, and by heating and successively cooling the electrical insulating sealing material C. The second sealing material B is in the form of a mesh. Thus, a sealed battery with few defectives such as a sealing failure and a short-circuit can be manufactured in a high yield rate.

    摘要： A nonaqueous electrolyte secondary cell having a rolled-up electrode unit housed in a cell can and comprising a positive electrode and a negative electrode each formed by coating a surface of a striplike current collector with an electrode material. According to a first embodiment, the current collector of at least one of the positive electrode and the negative electrode comprises a plurality of current collector pieces 42 arranged along one direction and a PTC element 5 interconnecting each pair of adjacent current collector pieces 42. Alternatively with a second embodiment, at least one of the positive electrode and the negative electrode comprises a PTC element held between opposed faces of an uncoated portion of the current collector thereof and a base end portion of a current collector tab. The PTC element serves to prevent continuous occurrence of a current in excess of a predetermined value and realizes a high energy density.

    摘要： A nonaqueous electrolyte battery having improved storage stability is disclosed. The battery includes a positive electrode; s negative electrode in which the active material is lithium or a compound capable of absorbing and desorbing lithium; and a nonaqueous electrolyte containing an organic solvent, at least 10 wt % of which is dioxolane, a solute and a storage stabilizing additive which is an oxygen acid ester, isoxazole, oxazole or oxazoline or a derivative thereof. The additive reduces the self-discharge rate of the battery during storage.
