ABSTRACT:
A rechargeable electrochemical cell is provided having an improved current collector which provides an electrical path from one of the cell electrodes to a terminal external to the cell. The collector is provided with resilient deflectable tabs which reside in the cell in a deflected state between the electrode and the container and which exert a contact force establishing electrically conductive contact between a spiral edge segment of the electrode and a contact edge on the tab.
