Lithium anode with conductive foil and anode tab for rechargeable lithium battery

摘要

Lithium based electrical cells having a new anode electrode construction are described. The cells have a sandwich construction of lithium sheet, conductive foil and lithium sheet, wherein the anode tab is welded directly onto the conductive foil not onto the lithium. Alternatively, the tab is connected onto the lithium in an area where the lithium does not dissolve during discharge, so that the tab will not become disconnected from the anode sheet.
