Abstract

A process for delineating a population of electrode structures in a web is disclosed. The web has a down-web direction, a cross-web direction, an electrochemically active layer, and an electrically conductive layer. The process includes laser machining the web in at least the cross-web direction to delineate members of the electrode structure population in the web without releasing the delineated members from the web and forming an alignment feature in the web that is adapted for locating each delineated member of the electrode structure population in the web.
