1. A method for forming a battery assembly including:
a) stacking a plurality of battery plates to form a plurality of electrochemical cells;
wherein one or more individual battery plates include a plurality of projections extending from and about an exterior periphery of an individual battery plate toward one or more adjacent battery plates;
wherein the plurality of projections of the individual battery plate are integrally formed with a substrate of the individual battery plate;
wherein upon the stacking, the plurality of projections of the one or more individual battery plates overlap about an exterior peripheral surface of the one or more adjacent battery plates such that the plurality of projections are located on an exterior of a stack of the plurality of battery plates;
b) welding about the exterior periphery of the plurality of battery plates to form one or more integrated edge seals such that the one or more individual battery plates are bonded to the one or more adjacent battery plates; and
wherein the one or more integrated edge seals are formed by the plurality of projections bonding to the exterior peripheral surface of the one or more adjacent battery plates upon which the plurality of projections are overlapped on.
