Electrical connection to a bundle of connectors for electrodes

The system has positive and negative electrodes with metallic liners. The liners have a non-coated lateral band (65) emerging from opposite sides of a bundle (63). The liners of same polarity are folded, in a direction perpendicular to their initial direction, to a height equal to a distance separating them from the neighboring liners of the same polarity for forming a socket on which a plane connection is welded. Independent claims are also included for the following: (a) an electro-chemical generator having connection system (b) a process of connecting a plane connection to electrodes of same polarity of an electro-chemical bundle.
