  • Patent number: 4099218
    Abstract: A method of making porous polymer containing separators adapted for use in electrolytic electrical devices, particularly electrolytic capacitors, the separator capable of absorbing and retaining electrolyte and devices utilizing the resultant separators. The method includes the steps of loading a semi-liquid or liquid polymer containing material with at least one compound and at least one modifier material, solidifying the polymer containing material, and removing at least some of the compound to provide a porous polymer containing separator capable of absorbing and retaining electrolyte. When the separators of the present invention are utilized in electrolytic capacitors, especially aluminum electrolytic capacitors, reductions in capacitor volume without significant loss of capacitance are realized and capacitor manufacture is facilitated.

  • Patent number: 4085256
    Abstract: An anode coating for anhydrous electrochemical generating cells is disclosed wherein the anode active material is coated with the insoluble reaction product of the anode metal with an inhibiting reactant such as CO.sub.2, SO.sub.2, O.sub.2, NH.sub.3, and N.sub.2 saturated with respect to water vapor H.sub.2 O. This coating is insoluble in the cell under open circuit conditions and is stable with regard to said electrolyte but is soluble in said electrolyte, when the cell is discharged with a negligible over voltage. The coated anodes and the method for making same are specifically described. Cells with anodes treated according to this invention have been stored at 55.degree. C, for extended periods with negligible self discharge.

An assembly, closing the open end of the container, includes a first layer adjacent the electrical body with a positioning means projecting into a receptacle of the electrical body.A disc-like member has a positioning means extending therefrom. A recess (or recesses as the case may be) is formed in the disc-like member and provides a membrane adapted to be punctured by a substantially rigid member such as the terminal of the electrical body. Optionally, a vent may be formed in the disc-like member to provide a rupturable elevated pressure release means.
