摘要： A method of electrowinning a metal by electrolysis of a melt containing a dissolved species of the metal to be won using a non-consumable anode having a metal, alloy or cermet substrate and an operative anode surface which is a protective surface coating of cerium oxyfluoride preserved by maintaining in the melt a suitable concentration of cerium, is characterized by using an anode provided with an electronically conductive oxygen barrier on the surface of the metal, alloy or cermet substrate. The barrier layer may be a chromium oxide film on a chromium-containing alloy substrate. Preferably the barrier layer carries a ceramic oxide layer, e.g. of stabilized copper oxide which acts as anchorage for the cerium oxyfluoride.

摘要： A copper metal foam, or a large pore size metal foam, particularly a large pore size nickel metal foam, is utilized as a support for a negative electrode in a metal hydride alkaline secondary battery. Or a copper metal foam is employed as a support for an electrode of alithium-ion secondary battery. The metal foam for the electrode support is a light weight, typically very flexible foam. The metal foam is particularly serviceable as an electrode support for a hydrogen storage alloy negative electrode, e.g., an electrode containing an active material of metallic alloy, such as an AB5 class of alloy or an AB2 class of alloy. As a support for an alkaline secondary battery negative electrode, the large pore metal foam may also serve as the negative cadmium electrode for a nickel-cadmium battery. As copper metal foam, the foam may further serve as the support for the positive or negative electrode, or for both, for a lithium-ion secondary battery.

摘要： A porous product, typically a metal foam sheet, is produced as a tailored, engineered product. The porous product can have enhancec strength, as well as more desirable electrical and mechanical properties. The product which first exists typically as a flexible, generally polymeric foam sheet in strip (12) form, which strip (12) is produced in the longitudinal direction, is stretched in a direction other than its direction of production. The porous product can have pores which would be anisotropic in form in usual production, which are stretched to at least substantially isotropic form. The product can even be tailored to have pores which are anisotropic in the direction of the stretch. Thus, an engineered product can be produced which, for example, as an open-cell metal foam prepared from a polymeric foam, can have conductivity, both thermal and electrical, as well as strength and ductibility, tailored for greater uniformity and performance.
