An electrical storage cell is provided comprising a container (2) carrying an electrode plate group (9) comprising alternating positive and negative electrodes flanking electrolyte-impregnated separators, a current output terminal (7) passing through a wall (5) of the container, and an internal connection part (20) 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 (25, 26), eliminating the need for supplementary welding parts employed for welding the copper internal connection.
