Abstract
A battery unit includes a battery having an anode including an anode current collector tab, a cathode including a cathode current collector tab, and an electrolyte disposed between the anode and the cathode. The battery is sealed by packaging material such that portions of the anode current collector tab and the cathode current collector tab extend past the exterior of the packaging material. The extended portions of the anode current collector tab and the cathode current collector tab are secured to the exterior of the packaging material to reinforce the extended portions.
