Abstract (en)
[origin: WO2013023769A1] The electrochemical energy storing device has an energy storing cell (10) with an electrode stack and a casing; and at least one current collector (12) which has a first contact portion (12a) that is connected to the electrode stack of the energy storing cell (10) in an electrically conductive manner and a second contact portion (12b) that is arranged at least partly outside of the casing of the energy storing cell (10). At least one contact element (14) is further provided which has a first contact portion (14a) that is connected to the second contact portion (12b) of the current collector (12) in an electrically conductive manner, preferably welded face-to-face using ultrasound, and a second contact portion (14b) for electrically contacting the energy storing device. The first contact portion (12a) and the second contact portion (12b) of the current collector (12) are first oriented in a substantially perpendicular manner relative to each other, and the second contact portion (12b) of the current collector (12) is bent after being welded to the first contact portion (14a) of the contact element (14) so as to then run substantially parallel to the first contact portion (12a) of the current collector (12).
