Abstract
A process for delineating a population of electrode structures in a web includes laser ablating the web to form ablations in the web, each ablation being formed by removing a portion of an electrochemically active layer to thereby expose a portion of an electrically conductive layer. The process includes forming alignment features in the web that are formed at predetermined locations on the web. The process also includes laser machining the web to form weakened tear patterns in the web that delineate members of the electrode structure population, each of the delineated members being individually bounded, at least in part, by a member of the weakened tear patterns that is adapted to facilitate separation of delineated members, individually, from the web by an application of a force, the alignment features being used to aid in the formation of the weakened tear patterns.
