摘要：An electrochemical cell is disclosed having a cylindrical can having an open endand a closed end, and a first electrode having a generally hollow cylindrical shapemolded in place within the can such that an outer cylindrical surface of the first electrodecontacts an inner cylindrical surface of the can. The first electrode has a recess adjacentto the inner cylindrical surface of the can at an end of the first electrode proximate theopen end of the can to accommodate any flashing that is formed along the interior sidewalls of the can when the first electrode is molded in place. The electrochemical cellfurther includes a second electrode having a polarity opposite the first electrodedisposed within a hollow cavity of the first electrode, a separator lining the hollow cavitywithin the first electrode so as to physically separate the first and second electrodes, anda collector assembly supported by the first electrode for sealing the open end of thecan. As an alternative to providing a recess in the first electrode, a flat annular ring madeof electrochemically active material may be provided between the flat upper surface ofthe first electrode and the bottom surface of the collector assembly.
