Method for joining a metallic current collector to an electrode comprising a fibrous or a spongeous supporting structure for electrochemical generator and electrode obtained thereby

摘要

Method for connecting a metallic connection on to an electrode whose core has a fibrous or spongy (foam) structure, for an electrochemical generator, and electrode obtained, according to which method at least one metallic strip is applied on to an edge of the said core and compression-welding is carried out, which method is characterised in that, at least in line with the welding region between the said strip (24) and the so-called main core (22), a holding core (27) which is similar in nature to the main core is arranged prior to welding.
