Abstract
Abstract A reticulate primary electrode, usually cathode, and method for making for use in an electrochemical cell. The cathode is openly porous, in substantial physical contact with a separator used in the cell for separating anode and cathode compartment within the cell, and intermetallically bound to a cathodic current collector used within the cell.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
In an electrolytic cell having anode and cathode compartment defined by a separator, an electrode assembly comprising: (a) an electrode/current feeder unit having an openly porous, reticulate electrode and a surface uniform current feeder of plated metal, said electrode substantially filling at least one of said compartments and in substantial physical contract with said separator, with the plating for the plated metal forming said electrode while intermetallically binding by electroplate only said current feeder and electrode together into said unit, whereby electrical current is distributed to the metal plate electrode with negligible electrical resistance between the electrode and current feeder; and (b) distribution means whereby electrolyte can be circulated into the reticulate electrode compartment and out of the electrode compartment.
Claim 2
Dependent Claim
120 words
In an electrolytic cell having anode and cathode compartment defined by a separator, an electrode assembly comprising: (a) an electrode/current feeder unit having an openly porous, reticulate electrode and a surface uniform current feeder of plated metal, said electrode substantially filling at least one of said compartments and in substantial physical contract with said separator, with the plating for the plated metal forming said electrode while intermetallically binding by electroplate only said current feeder and electrode together into said unit, whereby electrical current is distributed to the metal plate electrode with negligible electrical resistance between the electrode and current feeder; and (b) distribution means whereby electrolyte can be circulated into the reticulate electrode compartment and out of the electrode compartment.
Claim 3
Dependent Claim
