    Abstract: An electric storage battery including a jelly roll type electrode assembly having a mandrel. The mandrel includes a positive portion, negative portion and removable portion. The mandrel has two faces with grooves dimensioned to accommodate positive and negative feedthrough pins. Electrodes are welded to the mandrel using an ultrasonic weld to the face on which the electrodes are attached. An additional weld is made to at least one ultrasonic weld using a through-mandrel laser weld, incident on the opposite face from which the ultrasonic weld. The laser melts the mandrel such that molten mandrel material fills the area under the foil at the area of the ultrasonic weld, the surface area of the foil being significantly increased by knurls formed by ultrasonic welding. Electrodes are wrapped around the mandrel using the removable portion to wind the mandrel. The mandrel allows tighter wrapping of the jelly roll assembly increasing battery miniaturization.

  • Patent number: 8470057
    Abstract: A method for producing an alkaline primary battery includes: (1) forming a cylindrical positive electrode having a hollow; (2) inserting a cylindrical separator with a bottom into the hollow of the positive electrode, the separator including: a wound cylindrical portion; and a bottom portion that is substantially U-shaped in cross-section, the bottom portion covering an opening of the cylindrical portion at a lower end thereof and having an upstanding portion that extends along a lower outer face of the cylindrical portion; and (3) injecting an electrolyte into the separator. The amount of the electrolyte injected into the separator in the step (3) is sufficient to impregnate the positive electrode and the separator and immerse a lower end of the cylindrical portion of the separator in the electrolyte remaining in the separator, thereby bringing the lower end of the cylindrical portion into contact with the upstanding portion.
