ELECTROCHEMICAL CELL HAVING INCREASED ANODE-TO-CATHODE INTERFACE AREA

摘要

An electrochemical cell having a large anode-to-cathode interface area which achieves low current density to provide high cell efficiency. The electrochemical cell includes a can containing a first electrode and a second electrode. The first electrode has an outer perimeter which substantially conforms to the interior walls of the can and further has a non-cylindrical cavity provided therein. The second electrode is disposed within the non-cylindrical cavity of the first electrode. The first and second electrodes provide an interface area that varies along the length of the cell. A separator is disposed between the first and second electrodes and a cover and seal assembly is assembled to an open top end of the can.
