Abstract

See full text

A method for producing a button cell includes providing a cell cup, a cell top and an electrode-separator assembly winding, the electrode-separator assembly winding having a positive electrode and a negative electrode. An electrically insulating seal is applied at least to an outer portion of the cell top casing. The electrode-separator assembly winding is inserted into the cell top. The cell top is inserted into the cell cup to form a housing. A pressure is applied in a radial direction perpendicular to an axis of the electrode-separator assembly winding so as to seal the housing.
