Patent number: 5360678Abstract: A pressure tolerant high energy density battery (10) is described. The battery has a metal casing (12) having a pressure compensating means in the form of bellows (30) comprising a plurality of successive convolutions individually welded to one end of the battery opposite a terminal conductor (20). The conductor is mounted on the header (18) by a glass seal (22) and the active components for the battery comprise a cathode means (34) preferably made of either carbon or fluorinated carbon (CFx) and a binder sheeted on a metal foil and an anode means (36) preferably made by laminating battery grade lithium onto metal grids. A separator (38) is provided between the active battery components and the electrodes and separator are rolled into a spirally wound type formation and housed inside the battery, supported above the bellows.Type: GrantFiled: October 19, 1992Date of Patent: November 1, 1994Assignee: Wilson Greatbatch Ltd.Inventors: David M.

Patent number: 4737249Abstract: A process for the electrochemical production of hydrogen from an aqueous alkaline electrolyte characterized by the use as a cathode of a material having the general formula AB.sub.5 H.sub.x wherein A is one or more of rare earth metals and calcium, B is nickel or cobalt and x is a number, generally from 4 to 8 characteristic of saturation of the AB.sub.5 -compound with hydrogen. The hydrogen is generated at a relatively low overpotential and thus at high efficiency.Type: GrantFiled: February 12, 1986Date of Patent: April 12, 1988Assignee: Inco Alloys International, Inc.Inventors: Vance R. Shepard, Jr., Dale E. Hall, John T. Arms, William D. K. Clark

Patent number: 4385019Abstract: A process is provided for forming a polymeric material which can be developed into a shaped polymeric structure comprising an active material encradled in a porous, fiber-containing polymeric composition. In the process, the active material is mixed with a tripartite system comprising a fibrillatable polymer, a support-contributing polymer and a pore-former. When such a system is mixed and developed with an active material, such as LaNi.sub.5, an active composition is produced which may be used, for example, as a hydrogen collecting or storing material.Type: GrantFiled: January 19, 1981Date of Patent: May 24, 1983Assignee: MPD Technology CorporationInventors: Philip Bernstein, James P. Coffey, Alan E. Varker, John T. Arms, William D. K. Clark, Paul D. Goodell
