Abstract: An electrical device body including an electrode and a radiation semi-cured or cured polymer containing material. The electrode is formed into a configuration such as a convolutely wound electrical device body. The radiation semi-cured or cured polymer containing material is disposed over the body to help maintain the configuration of the body.A method of making the electrical device body including the steps of applying radiation curable polymer containing material to an electrode formed into a configuration such as a convolutely wound body configuration, irradiating applied material to semi-cure or completely cure the applied material and help maintain the configuration of the body.High energy irradiation from an energy source such as ultra-violet light or an electron beam is used to cross-link or cure applied polymeric material.

Abstract: An electrical device comprising an electrical body in a container with terminals extending through an open end of the container. The electrical body has receptacles at opposite ends thereof. A positioning means is located at an end of the container opposite the open end thereof and projects into a receptacle of the electrical body. 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.

Abstract: An electrical device of the electrolytic type comprising an electrically insulating radiation semi-cured or cured polymer containing material over an electrical body to confine mobile electrolyte contiguous to the body. Preferably, the electrical body includes electrode means selected from the group consisting of stacked anode and cathode electrodes, or convolutely wound anode and cathode electrodes. Adjacent anode and cathode electrodes are separated by a suitable spacer, preferably paper and the like. The mobile electrolyte includes liquid and semi-liquid electrolytes.The method of making the electrical device includes the steps of applying radiation curable polymer containing material to the electrical body containing the mobile electrolyte, and irradiating the applied polymer containing material to cure or semi-cure the material to confine mobile electrolyte contiguous to the body.
