BUTTON CELL HAVING WINDING ELECTRODE AND METHOD FOR THE PRODUCTION THEREOF

A method for producing a button cell includes providing a metal cell cup, providing a metal cell top, and providing a first electrode and a second electrode. The first electrode includes a first current collector partially coated with a first active electrode material and having an active material-free region. The second electrode includes a second current collector partially coated with a second active electrode material and having an active material-free region. The method further includes attaching a first metal foil conductor to the active material-free region of the first current collector, attaching a second metal foil conductor to the active material-free region of the second current collector, and forming a cylindrical electrode winding by winding, in a spiral, an electrode assembly. The first and second metal foil conductors extend out of the cylindrical electrode winding from first and second end faces of the cylindrical electrode winding.
