摘要： A prismatic battery is provided with a fixing portion composed of projections 29Aa and 29Ba for fixing the position of a flat electrode assembly 11 and a battery outer can 12 by contacting with an insulating sheet 32 on at least one of a positive electrode collector member 16 and a negative electrode collector member 18. The insulating sheet 32 is provided between the projections 29Aa, 29Ba and the battery outer can 12. Tips 29Ab and 29Bb of the projections 29Aa and 29Ba project from the flat electrode assembly 11 towards the battery outer can 12 side. The height of the projections is smaller than the thickness of the insulating sheet 32. This prevents short-circuiting between the positive electrode collector member or the negative electrode collector member, and the battery outer can. Thus, a prismatic battery suitable for EVs and HEVs with excellent safety can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a square battery optimum for an EV or an HEV hard to be damaged on the surface of a flat electrode body when it is housed in a square metallic battery outer can. SOLUTION: The square battery has a flat electrode body 11 in which a positive electrode core exposed part 14 and a negative electrode core exposed part 15 are formed in the opposite direction each other, the positive electrode core exposed part 14 and the negative electrode core exposed part 15 are bundled and welded to a positive current collector 16 and a negative current collector 18 1 respectively, the flat electrode body 11 is housed in the battery outer can, the positive current collector 16 and the negative current collector 18 1 each has a positioning projection (for example 18 1 a, 18 1 b) in the same direction in at least one, the peripheral part and the bottom part of the flat electrode body 11 are covered with an insulating sheet material 30 1 , and portions where positioning projections of the positive current collector 16 and the negative current collector 18 1 are formed are doubly covered with the insulating sheet material 30 1 .

摘要： A prismatic nonaqueous electrolyte secondary battery of the invention includes a process whereby a cylindrical electrode roll is produced by spirally rolling negative electrode plates made of elongated sheet-like negative electrode substrates to which is applied a negative electrode mixture containing negative electrode active material, and positive electrode plates made of elongated sheet-like positive electrode substrates to which is applied a positive electrode mixture containing positive electrode active material, insulated from each other by separators; and then the cylindrical electrode roll is crushed to be formed into a flattened electrode roll; the process of crushing the cylindrical electrode roll to form a flattened electrode roll being controlled so that, in the flattened electrode roll the ratio of change in the separator gas permeability between the winding start and the winding end is 55% or less of the gas permeability at the winding start. By providing such a configuration, a prismatic nonaqueous electrolyte secondary battery and a method for manufacturing the same can be obtained, in which gas permeability of separators does not increase during manufacturing of a flattened electrode roll thereby making possible to achieve a high discharge output.
