摘要： A package for a material containing a non-aqueous solvent, which water enters little from outside and has a strength hardly degrading for a long time and a non-aqueous electrolyte cell having a long life and a high reliability are disclosed. A package for a material containing a non-aqueous solvent having a baglike structure in which part of a film of a lamination of metallic layers and resin layers is bonded, wherein an organic layer between the metallic layers of the bonded part includes a structure for suppressing the penetration of the non-aqueous solvent contained in the package.

摘要： A cell developed to solve the problem of a conventional cell having a negative electrode containing metallic lithium that a large short-circuit current flows when the temperature of the cell is raised due to internal short circuit, whereby the temperature of the cell is further raised due to heat buildup and a further increased short-circuit current flows. Specifically a cell in which a negative electrode (2) contains metallic lithium, a positive electrode (1) contains a positive electrode active material (8) and an electron conductive material (9) in contact with the positive electrode active material (8), and an electrolytic layer (3) is sandwiched between the positive electrode (1) and the negative electrode (2). The electron conductive material (9) contains an electrically conductive filler and a resin and has resistance increasing with temperature.
