  • Control of edge effects of oxidant electrode
    Patent number: 4288507
    Abstract: Described is an electrode assembly comprising;a. a porous electrode having a first and second exterior face with a cavity formed in the interior between said exterior faces thereby having first and second interior faces positioned opposite the first and second exterior faces;b. a counter electrode positioned facing each of the first and second exterior faces of the porous electrode;c. means for passing an oxidant through said porous electrode; andd. screening means for blocking the interior face of the porous electrode a greater amount than the blocking of the respective exterior face of the porous electrode, thereby maintaining a differential of oxidant electrode surface between the interior face and the exterior face.The electrode assembly is useful in a metal, halogen, halogen hydrate electrical energy storage device.
    Type: Grant
    Filed: July 21, 1980
    Date of Patent: September 8, 1981
    Assignee: Energy Development Associates, Inc.
