摘要： 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.

摘要： A secondary battery for cycling between a charged and a discharged state is provided. The secondary battery has an electrode assembly having a population of anode structures, a population of cathode structures, and an electrically insulating microporous separator material. The electrode assembly also has a set of electrode constraints that at least partially restrains growth of the electrode assembly. Members of the anode structure population have a first cross-sectional area, A1 when the secondary battery is in the charged state and a second cross-sectional area, A2, when the secondary battery is in the discharged state, and members of the cathode structure population have a first cross-sectional area, C1 when the secondary battery is in the charged state and a second cross-sectional area, C2, when the secondary battery is in the discharged state, where A1 is greater than A2, and C1 is less than C2.
