BATTERY, IN PARTICULAR A BUTTON CELL, AND METHOD FOR MANUFACTURING SAME

A battery, in particular a button cell, and a method for manufacturing the same are provided. The present invention relates to a method for manufacturing a battery comprising a casing provided with acup and a closure part for said cup, the method comprising the successive steps consisting in providing at least three parts with a first part defining one pole, and a second part and a third part defining the other pole and intended to form together the cup, the first and second parts respectively comprising a first surface and a second surface of matching shape, at least one adhesive portion ofeach of said surfaces extending in a geometric surface non-parallel to the general axis of the battery; bonding the aforementioned first and second surfaces to provide a structure with an adhesive joint between the first and second parts; welding the third part to the second part; the adhesive joint being arranged against an inner face of the cup, the aforementioned adhesive portion of the secondpart form a stop, along the general axis, for the first part, which is located inside the cup.
