摘要： A secondary battery is provided for cycling between a charged and a discharged state, the secondary battery including a battery enclosure, an electrode assembly, carrier ions, a non-aqueous liquid electrolyte within the battery enclosure, and a set of electrode constraints. The set of electrode constraints includes a primary constraint system having first and second primary growth constraints and at least one primary connecting member, the first and second primary growth constraints separated from each other in the longitudinal direction, wherein the primary constraint array restrains growth of the electrode assembly in the longitudinal direction such that any increase in the Feret diameter of the electrode assembly in the longitudinal direction over 20 consecutive cycles of the secondary battery is less than 20%. The set of electrode constraints further includes a secondary constraint system having first and second secondary growth constraints connected by at least one secondary connecting member, wherein the secondary constraint system at least partially restrains growth of the electrode assembly in a second direction upon cycling of the secondary battery.

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.

摘要： 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.
