An electrochemical cell construction having a large anode-to-cathode interfacial surface area to realise improved high rate service performance i n an easy-to-manufacture construction. A first electrode, such as the cathode, is formed having a conductive current collector integrally embedded therein. Separator material is disposed on both the inner and outer cylindrical walls of the first electrode. An outer electrochemically active material covers th e outer separator material outside of the first electrode and an outer insulation is layered on top of the outer electrochemically active material to form a cathode bobbin. The cathode bobbin is disposed into a container havin g a closed bottom end and an open top end. A second electrode, such as an anod e, is disposed in the inner cylindrical volume formed in the first electrode an d a conductive path is provided between the outer electrochemically active material and the second electrode. The current collector is disposed in contact with the first electrode, and a cover assembly is assembled to the open end of the container. |
