A galvanic cell comprising a coiled electrode assembly (19) housed in a conductive container (10) having a base with an upstanding wall (26) defining an open end and closed by a cover (25) the coiled electrode assembly (19) comprises a first electrode (11), a second electrode (13) superimposed on the first electrode and a separator (12) disposed between the first electrode (11) and the second electrode (13) and over at least one of the first and second electrodes (11,13); the first electrode (11), second electrode (13) and separator (12) being spirally wound such that the first electrode (11) is electronically insulated from the second electrode (13) by the separator (12) and a portion (24) of the first electrode (11) is exposed to define at least a portion of the outer wall of the coiled electrode assembly (19) and a portion (14) of the second electrode (13) is exposed to define at least a portion of the inner wall of the coiled electrode assembly (19); the coiled electrode assembly (19) being disposed within the container (10) such that the exposed first electrode (24) defining at least a portion of the outer wall of the coiled electrode assembly (19) is in pressure contact with the container (10) thereby adapting the container (10) as the first terminal for the galvanic cell; a flexible electrically conductive member (20) being disposed within the opening defined by the inner wall of the coiled electrode assembly and pressure contacting at least a portion of the exposed surface of the second electrode assembly and pressure contacting at least a portion of the exposed surface of the second electrode and exerting a radially outward force on the exposed second electrode defining a portion of the inner wall of the coiled electrode assembly; and the flexible electrically conductive member being secured to an electrically conductive terminal at the exterior surface of the galvanic cell, the electrically conductive terminal being electrically insulated from the first terminal so that the electrically conductive terminal is adapted as the second terminal for the galvanic cell. |
