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.
Claims16
A battery unit, comprising:
- 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;
- packaging material surrounding the battery to form a package having top and bottom sides, at least a portion of the anode current collector tab and at least a portion of the cathode current collector tab extending past an exterior surface of the packaging material;
- the extended portions of the anode current collector tab and the cathode current collector tab being secured to the exterior surface of the packaging material on at least one of the top and bottom sides of the package.
A battery unit, comprising:
- 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;
- packaging material surrounding the battery to form a package having top and bottom sides, at least a portion of the anode current collector tab and at least a portion of the cathode current collector tab extending past an exterior surface of the packaging material;
- the extended portions of the anode current collector tab and the cathode current collector tab being secured to the exterior surface of the packaging material on at least one of the top and bottom sides of the package;
- and
- cushioning means secured on sides of the package opposite from the securement of the anode current collector tab and the cathode current collector tab.
A method of making a battery unit, comprising the steps of:
- attaching together an anode including an anode current collector tab, an electrolyte, and a cathode including a cathode current collector tab, such that the electrolyte is disposed between the anode and the cathode, thereby forming a battery;
- surrounding the battery with a packaging material to form a package having a top and a bottom side, at least a portion of the anode current collector tab and at least a portion of the cathode current collector tab extending past the exterior of the packaging material;
- securing the anode current collector tab and the cathode current collector tab to the exterior of the packaging material on at least one of the top and bottom sides of the package.
