Abstract
A Li-ion or Li-ion polymer battery, comprised of a battery assembly having a plurality of generally planar cathode sections, each having a flat, metallic cathode current collector tab extending therefrom. A cathode tab weldment joins the cathode current collector tabs together with a cathode battery lead, and an anode tab weldment joins the anode current collector tabs together with an anode battery lead. A battery package contains the battery assembly with the anode tab weldment and the cathode tab weldment within the package and the anode and cathode battery leads extend through the package. A protective insert within the battery package surrounds the anode and cathode tab weldments and isolates the weldments from the battery package. The insert surrounds the battery leads where the battery leads extend through the package.
