Abstract
A method of bonding a metal connection to an electrode including a core having a fiber or foam-type structure for an electrochemical cell, in which method at least one metal strip is pressed against one edge of the core and is welded thereto under compression, wherein, at least in line with the region in which the strip is welded to the core, which is referred to as the "main core", a retaining core of a type analogous to that of the main core is disposed prior to the welding.
Claims14
An electrode for an electrochemical cell, said electrode comprising:
- a main core having one of a fiber and a foam structure;
- a metal connection for securing said electrode in said electrochemical cell, said metal connection comprising at least one metal strip;
- and
- a retaining core having substantially the same fiber or foam structure as said main core, but different dimensional characteristics, wherein
- said metal connection is fixedly secured to respective edge portions of said main core and said retaining core.
