An electrochemical cell construction having a large anode-to-cathode interfacial surface area to realize improved high rate service performance in 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 the 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 having a closed bottom end and an open top end. A second electrode, such as an anode, is disposed in the inner cylindrical volume formed in the first electrode and a conductive path is provided between the outer electrochemically active material and the second electrode. A current collector is disposed in contact with the second electrode, and a cover assembly is assembled to the open end of the container. |
