ABSTRACT:
In a voltaic cell, especially in the form of a button cell, with a metal housing sealed liquid-tight including a cell cup and a cell lid electrically insulated against it by a seal, the seal is formed from a sealing part produced by deep drawing from a plastic film. This sealing part is shrink-fitted onto the edge of the cell lid. To produce the voltaic cell, a sealing part is formed by deep drawing from a plastic film, which sealing part is subsequently placed on the edge of the cell lid, shrink-fitted onto the edge of the cell lid and the cell cup is flanged around it.
