Battery with lead/nugget protection insert
First Claim
1. 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, and one or more generally planar anode sections each having a flat, metallic anode current collector tab extending therefrom, said cathode sections and one or more anode sections being stacked together, wherein said cathode current collector tabs are aligned and said anode current collector tabs are aligned;
a cathode tab weldment joining said cathode current collector tabs together and to a cathode battery lead; and
an anode tab weldment joining said anode current collector tabs together and to an anode battery lead;
a battery package containing said battery assembly, said battery package having an interior space for receiving said anode tab weldment and said cathode tab weldment, said anode and cathode battery leads extending through said packaging to form external battery leads; and
a protective insert within said battery package disposed within said space, said insert surrounding said anode and cathode tab weldments and isolating said weldments from said battery package, said insert surrounding said battery leads where said battery leads extend through said package.

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.
