A terminal structure and seal for an electrochemical cell includes a terminal post inside a plastic tubular member which is inside a metal barrel. The plastic tubular member is unitary with the plastic cover and a reinforcing boss on the cover is annular and an annular stabilizing flange unitary with the metal barrel is embedded in this reinforcing boss. The metal barrel is separated from the interior of the electrochemical cell so that the metal barrel need not be resistant to the electrolyte and so that there is no potential leakage path between internal threads on the metal barrel and external threads on the plastic tubular member. The foregoing Abstract is merely a resume of general applications, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Terminal structure and seal

A battery terminal connector provides similar connector assemblies for electrodes of similar polarity. Each connector includes a U-shaped collector plate providing spaced and parallel flanges extending to spaced and parallel edges. U-shaped tabs are mounted on each electrode and provide legs which extend up along the outer sides of the associated flanges. Each leg provides an edge in alignment with the edge of the associated flange. An edge weld, extending lengthwise of the associated flange edge, connects the adjacent legs. In one embodiment, the legs are twisted so that their end edges extend lengthwise along the edge of the associated flange. In another embodiment, the legs are not twisted and engage the associated flange along the edge of the legs.
