1. A method for assembling a battery plate comprising:
a) placing a transfer sheet on a movable plate in a mold which is an electrode mold, wherein the movable plate is disposed opposite of an opening in the electrode mold and is movable in a direction of and through the opening in the electrode mold;
b) injecting an active material in a form of a paste on to the transfer sheet on the movable plate so that the active material forms a layer in a shape formed by at least the movable plate;
c) placing a substrate over the opening of the mold such that an area of one surface of the substrate upon which the active material is desired to be located is lined up with the active material in the mold;
d) contacting and then bonding the active material contacted to the substrate;
e) retracting the movable plate and the substrate away from one another such that the active material remains bonded to the one surface of the substrate and the transfer sheet remains bonded to a surface of the active material opposite of a surface of the active material bonded to the one surface of the substrate; and
wherein the active material on the one surface of the substrate forms a cathode and the active material on an opposite surface of the substrate forms an anode.
