Electrical interconnection system for electrochemical generators and batteries
First Claim
1. Electrical interconnection system for electrochemical generators including electrodes and connection members providing continuity of electrical current flow from the electrodes to an exterior of said generators, said system characterized in that said electrodes are connected to said connection members by means of mechanical and electrical joints, wherein each joint comprises a deformation area in which there is initially a substantially plane contact surface between a connection member and the electrodes to be joined, said connection member and the electrodes joined to it having been plastically deformed together in a common direction in said deformation area to form said joint, and wherein said joint is situated at a sufficient distance from edges of said electrodes and said connection members such that said edges are not deformed, said plastic deformation comprising cold flow of material of said electrodes and said connection members in parallel in said common direction, thereby immobilizing said electrodes and said connection members relative to each other, only said electrodes and said connection members contributing to said joint and being in intimate contact throughout the area subject to deformation.

Abstract
An electrical interconnection system for electrochemical generators including electrodes and connection members providing continuity of electrical current flow from the electrodes to the exterior of said generators connects the electrodes to the connection members and the connection members to each other by means of a mechanical and electrical joint. In an area in which there is initially a substantially plane contact surface between the parts to be joined, the joint is in the form of a plastic deformation of the parts to be joined and is situated at a sufficient distance from the edges of the parts for the edges not to be deformed. The plastic deformation consists in cold flow of the material of the parts in parallel directions in the same sense which immobilizes the parts relative to each other, only the parts contributing to the joint and being in intimate contact throughout the area subject to deformation.
