The laser beam melts the mandrel such that molten mandrel material fills the grooves welding the feedthrough pins in place. Electrodes are wrapped around the mandrel using the removable portion to wind the mandrel. The removable portion can be detached. The mandrel allows tighter wrapping of the jelly roll assembly and increasing battery miniaturization.

  • Patent number: 7684170
    Abstract: A multi-layer capacitor includes several electrically insulating layers that are stacked on top of one another. Parallel electrode plates are arranged between the insulating layers alternately one on top of the other, with each of the plates being separated by an intervening insulating layer. At least one first connecting line which extends perpendicularly through the layers is connected to one set of electrode plates and is insulated in relation to the other set of second electrode plates. Similarly, second connecting lines extend perpendicularly through the layers and are connected to the other set of plates and are insulated in relation to the one set of plates. The first connecting line extends centrally through the stacked electrode plates and is designed to carry a high-frequency signal.

  • Patent number: 7667949
    Abstract: A capacitor having improved surface breakdown voltage performance and a method for applying laser marking to capacitors which does not reduce capacitor surface breakdown voltage, can be applied using existing laser marking technologies and apparatus, and which results in a mark that is legible and clear, is disclosed. In a first exemplary embodiment a capacitor includes a laser mark which is located near one of the capacitor terminals. The exact location is not critical as long as the mark does not make physical contact with the terminal. Conventional laser marking technologies and apparatus may be used to fix the mark in the new location. In a second embodiment the laser mark is oriented so that a flat portion of the mark is is oriented closest to the adjacent terminal.
