Multi-anode electrochemical cell with improved discharge performance

A method of manufacturing an electrochemical cell, the method comprising:

• placing a cathode within a cell housing comprising a cylindrical container having an interior radius xtot and a closure, wherein the cathode is in contact with an interior surface of the cylindrical container and defines a plurality of cylindrical openings, each cylindrical opening having an inner surface;
• covering the inner surface of each cylindrical opening of the plurality of cylindrical openings with a separator;
• wherein the separator has a thickness xs;
• disposing cylindrical anode within each cylindrical opening to form a plurality of anodes, wherein each cylindrical anode has a radius r2, wherein each cylindrical anode of the plurality of anodes is separated from the cathode by the separator;
• extending a current collector into each anode of the plurality of anodes, wherein the current collector is electrically connected to a negative terminal cover;
• and
• sealing the cylindrical container with the negative terminal cover;
