    摘要: An anode for an electrolytic capacitor is described. The anode is of a valve metal in powdered form, for example tantalum powder, that has been pressed into a pellet and sintered under a vacuum at high temperatures. Preferably, a poly(alkylene)carbonate binder is used to promote cohesion with the pressed powder body. The binder adds green strength to the pressed body and helps with powder flow before pressing. The poly(alkylene)carbonate binders are superior in that they leave virtually no residual carbon behind when burnt out during the sintering process. The pressed valve metal powder structure is then anodized to a desired voltage in a formation electrolyte to form a continuous dielectric oxide film on the sintered body as well as a terminal lead/anode lead weld extending therefrom.

    摘要: Methods for testing the hermeticity of casings for power sources intended to power implantable medical device by sensing the presence of vapors escaping from an electrolyte contained therein are described. More broadly, the present leak detection methods are applicable to any sealed enclosure having a first part sealed to a second part with a liquid contained therein. The liquid need not occupy the entire volume of the enclosure, but must contain at least one component having a vapor pressure at 25° C. of more than about 0.1 mm Hg. This component can assist in the functioning of the device such as an electrolyte, or be added for the sole purpose of leak detection.
