Title (EN) POWER STORAGE ELEMENT PRODUCTION METHOD AND POWER STORAGE ELEMENT
(FR) PROCÉDÉ DE PRODUCTION D’ÉLÉMENT DE STOCKAGE D'ÉNERGIE ET ÉLÉMENT DE STOCKAGE D'ÉNERGIE

Abstract:
(EN) The power storage element (10) production method comprises a swaging step (S2) of swaging a tip of an axial portion (220) passing through a positive pole terminal (201) or a positive electrode collector (130) and protruding downward from the positive pole terminal (201) or the positive electrode collector (130), thereby forming a swaged portion (230). In the swaging step (S2), the tip of the axial portion (220) swages with a punch (300) comprising a pressing surface (301) having a punch side first recessed portion (311) recessed downward, and a punch side second recessed portion (321) recessed further downward from the punch side first recessed portion (311) on a more inner peripheral side than the punch side first recessed portion (311).
(FR) L'invention concerne un procédé de production d'un élément de stockage d'énergie (10) qui comprend une étape de sertissage (S2) consistant à sertir une pointe d'une partie axiale (220) passant par une borne (201) de pôle positif ou un collecteur (130) d'électrode positive et faisant saillie vers le bas à partir de la borne (201) d'électrode positive ou du collecteur (130) d'électrode positive, formant ainsi une partie sertie (230). Dans l'étape de sertissage (S2), la pointe de la partie axiale (220) est sertie avec un poinçon (300) comprenant une surface de pression (301) ayant une première partie évidée (311) côté poinçon évidée vers le bas, et une seconde partie évidée (321) côté poinçon évidée davantage vers le bas à partir de la première partie évidée (311) côté poinçon sur un côté périphérique plus interne que la première partie évidée (311) côté poinçon.
(JA) 蓄電素子(10)の製造方法では、正極端子(201)又は正極集電体(130)を貫通して正極端子(201)又は正極集電体(130)から下方向に突出している軸部(220)の先端部をかしめることでかしめ部(230)を形成するかしめ工程(S2)を含んでいる。そして、かしめ工程(S2)では、下方向に凹むポンチ側第1凹部(311)と、ポンチ側第1凹部(311)よりも内周側においてポンチ側第1凹部(311)から下方向に更に凹んだポンチ側第2凹部(321)とを有する押圧面(301)を備えたポンチ(300)にて、軸部(220)の先端部をかしめる。
