Abstract
A sealed galvanic cell comprising a container and a cover having a coiled electrode assembly disposed in the container. The coiled electrode assembly has an inner exposed electrode of one polarity and an outer exposed electrode of the opposite polarity. A flexible electrically conductive member secured to the cover makes electrical contact with the inner exposed electrode and exerts a radially outward force therein while the outer exposed electrode makes electrical contact with the wall of the container.
