Abstract
Abstract An electrode structure for use with an electrolyte wherein an electrically conductive flowing particle bed stream within a compartment of the electrode structure establishes a plurality of electrochemical reaction sites at the interface of the particles and of the electrolyte. The flowing particle bed electrode structure finds a preferred application as an electrode in an electrically regenerable system, particularly as a rotatable zinc electrode in zinc-nickel oxide and zinc-air secondary cells.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
41 words
An electrode structure according to claim 1 wherein said current-collecting means inCludes at least the second opposing face of said container as said conductive surface in electrical contact with at least a major portion of said bed for collecting current therefrom.
Claim 2
Dependent Claim
45 words
An electrode structure according to claim 2 wherein said shallow cylindrical container has a substantially circular cross section and a ratio of outer diameter to axial length greater than 10:1, said container being divided into a plurality of compartments partially filled with said conductive particles.
Claim 3
Dependent Claim
21 words
An electrode structure according to claim 3 wherein said ratio of outer diameter to axial length is between 20:1 and 200:
Claim 4
Dependent Claim
17 words
An electrode structure according to claim 2 wherein said second opposing face comprises a porous conductive surface.
Claim 5
Dependent Claim
66 words
An electrode structure according to claim 1 wherein said shallow cylindrical container is insulated, both faces of said container comprise electrolyte-permeable porous insulated separators having a pore size smaller than those of the particles for retaining said particles in the compartment, the current-collecting means in electrical contact with at least a major portion of the electrically conductive flowing particle bed includes a peripherally disposed conductive surface.
Claim 6
Dependent Claim
27 words
An electrode structure according to claim 6 wherein said container is divided into a plurality of compartments by conductive radial members which also serve as current collectors.
Claim 7
Dependent Claim
101 words
An electrode structure according to claim 7 wherein said insulated shallow cylindrical container has a substantially circular cross section and a ratio of outer diameter to axial length between 20:1 and 200:1, said container being divided by conductive radial members into from three to 12 compartments partially filled with substantially spherical conductive particles having a diameter between 1 and 3 millimeters and less than the axial length of the container, and an axially disposed shaft means is fixedly attached to said container for rotating it at a preselected speed to provide said electrically conductive flowing particle bed streams within said compartments.
Claim 8
Dependent Claim
23 words
An electrode structure according to claim 8 wherein said conductive particles have an outer coating of zinc over an underlying layer of cadmium.
