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： Embodiments of secondary batteries having electrode assemblies are provided. A secondary battery can comprise an electrode assembly having a stacked series of layers, the stacked series of layers having an offset between electrode and counter-electrode layers in a unit cell member of the stacked series. A set of constraints can be provided with a primary constraint system with first and second primary growth constraints separated from each other in a longitudinal direction, and connected by at least one primary connecting member, and a secondary constraint system comprises first and second secondary growth constraints separated in a second direction and connected by members of the stacked series of layers. The primary constraint system may at least partially restrain growth of the electrode assembly in the longitudinal direction, and the secondary constraint system may at least partially restrain growth in the second direction that is orthogonal to the longitudinal direction.
