Patent number: 6569565Abstract: A method is disclosed in which the plates 2 of an electrode 1 are connected to a terminal 3 of a storage cell by clamping the plates 2 between the terminal 3 and a holding member such as a ring 6 or a washer 12 and then welding the plates 2 to the terminal 3 by transparent laser welding through the holding member. The plates 2 are preferably bent over a face of the terminal 3 before they are clamped. A tool 14 presses on an area 15 of the washer 12 to clamp the plates 2. The washer 12 and the plates 2 are then transparent laser welded to the terminal 3 along a weld line 16 around the area 15 on which the washer 12 bears. A storage cell that can be obtained by the above method is also disclosed.Type: GrantFiled: March 14, 2001Date of Patent: May 27, 2003Assignee: AlcatelInventors: Dominique Ligeois, Alexandre Chaillet, Philippe Borel
