    Abstract: A casing (12) having substantially parallel side walls (14,16) connected by a curved end wall receives a cathode electrode having substantially parallel opposed side walls connected by end walls. The cathode electrode (34) is enclosed by a separator envelope (44) that substantially conforms to an upper surface of the electrode. In contrast, the separator envelope has excess material at least at the opposite end. Accordingly, along the perimeter of the electrode the separator has a nonuniform spacing with respect to the edges of the electrode. The upper surface of the separator is disposed in a relatively closely spaced relationship with the electrode proximate the header and lid (24) where welding takes place. At the opposite end of the cathode electrode there is space inside the casing that provides for electrode swelling. Since no welding operations take place there, the separator is provided in a relatively loose relationship with respect to the cathode to accommodate swelling during discharge.

    Abstract: The present invention is directed to a header assembly attachable to a medical device for the purpose of connecting its output terminals to at least one lead, the lead terminating at a target organ or portion of the body intending to be assisted. A number of leads are connectable to the header, including single and coaxial leads. The header assembly may be molded directly to the medical device or preformed and then attached to the device casing, either by mechanical fastener and/or chemical adhesive.

    Abstract: This invention is directed to a novel solid polymer electrolyte more particularly thin film terpolymer networks are disclosed that are highly conductive at ambient temperatures. This solid polymer electrolyte can be produced as a thin film (14) that results from the polymerization of three selected monomers together with a lithium salt and plasticizers. The resulting solid polymer electrolyte does have excellent mechanical properties and ionic conductivity at ambient temperatures and can be used in the fabrication of a solid state battery and other solid state electrochemical devices such as supercapacitors, fuel cells, sensors, electrochromic devices or the like.

    Abstract: An alkali metal secondary electrochemical cell, and preferably a lithium ion cell (10), provided with a removable gas relief valve (12), is described. The gas release valve is positioned on the casing (14), in fluid flow communication between the inside thereof and the exterior. This gas release valve serves to eliminate cell gases that build up inside the casing during the cell's formation stage. Once the lithium-ion cell has completed formation, the gas release valve is removed and replaced with a hermetic closure. Removal of the gas release valve and sealing of the cell takes place in an environment in which no outside gas is capable of being introduced inside the casing. The cell can also be provided in a tank filled with inert gas and a filter which separates the cell gas from the inert gas. When cell formation is completed, the cell hermetically sealed.
