An electrochemical assembly includes a first stack of electrochemical elements provided with a first electrical connection tab with a first polarity. The first stack of electrochemical elements extends along a stacking plane. A first common connection element is adapted to electrically connect the first electrical connection tab to an electrical connection terminal with the first polarity.

Electrochemical assembly, corresponding battery and method

An electrical storage cell is provided comprising a container () carrying an electrode plate group () comprising alternating positive and negative electrodes flanking electrolyte-impregnated separators, a current output terminal () passing through a wall () of the container, and an internal connection part () electrically connecting the electrodes of one polarity to the terminal passing through a wall of the container, in which the internal connection part is of copper with at least one copper/nickel co-laminated portion (), eliminating the need for supplementary welding parts employed for welding the copper internal connection.
