Abstract
A cell with spiral-wound electrodes comprises a container, two current output terminals of opposite polarity carried by the container, each current output comprising a part exterior to the container and an internal part, and two electrodes spiral-wound about a longitudinal axis, one of positive polarity and the other of negative polarity, electrically connected to a corresponding current output. At least one terminal has a cylindrical shoulder having a diameter greater than the transverse dimension of the exterior part of the terminal. The electrode is provided with a plurality of conductive blade members in part substantially parallel to the longitudinal axis, mechanically and electrically connected to one edge of the electrode are projecting from this edge. The blade members are grouped together on and fixed to at least part of the periphery of the shoulder in order to establish electrical contact between the electrode and the current output.
