Claim 9:
10. A method of manufacturing an electrochemical cell, the method comprising:
placing an outer cathode ring within a container, wherein the outer cathode ring is in contact with an interior surface of the container and defines a cathode opening bounded by an inner surface of the outer cathode ring;
covering the inner surface of the outer cathode ring with a separator material;
positioning an inner cathode comprising an embedded cathode current collector and covered with a separator within the cathode opening of the outer cathode ring such that an outer surface of the inner cathode is spaced apart from the inner surface of the outer cathode ring, wherein the inner cathode has uniform characteristics across an entire radius of the inner cathode, and wherein the cathode current collector comprises a conductive tube;
disposing an anode material between the outer cathode ring and the inner cathode;
electrically connecting the cathode current collector with the container;
extending an anode current collector into the anode material; and
sealing the container with a cover, wherein the cover is in electrical connection with the anode current collector.
