Title:
A manufacturing method of a battery pack
Document Type and Number:
Japanese Patent JP6193236
Kind Code:
B2
Abstract:
A method for manufacturing a battery pack comprises a compressing step of stacking a plurality of flat secondary batteries, compressing and fixing in a pressed state of the flat secondary batteries constituting the battery staked member by applying a predetermined pressure in the stacking direction. Further, in the pressed shaping step, a pressing pressure of pressing the spiral electrode assembly is set, such that it is possible to insert the pressed electrode assembly into the outer can, and such that it is possible that the electrode assembly is swollen until the electrode assembly presses against the inner surface of the outer can when the electrode assemblies are swollen by the electrolyte injected into the outer can in the electrolyte injection step, and in the compressing step, the swollen electrode assemblies are pressed through the outer cans by pressing the outer cans of the flat secondary batteries.
