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, 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.
