Abstract: 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.

Abstract: Secondary batteries and methods of manufacture thereof are provided. A secondary battery can comprise an offset between electrode and counter-electrode layers in a unit cell. Secondary batteries can be prepared by removing a population of negative electrode subunits from a negative electrode sheet, the negative electrode sheet comprising a negative electrode sheet edge margin and at least one negative electrode sheet weakened region that is internal to the negative electrode sheet edge margin, removing a population of separator layer subunits from a separator sheet, and removing a population of positive electrode subunits from a positive electrode sheet, the positive electrode sheet comprising a positive electrode edge margin and at least one positive electrode sheet weakened region that is internal to the positive electrode sheet edge margin, and stacking members of the negative electrode subunit population, the separator layer subunit population and the positive electrode subunit population.

Abstract: A battery includes an electrode assembly. The electrode assembly has a population of unit cells, each unit cell including an electrode current collector layer, an electrode layer, a separator layer, a counter-electrode layer, and a counter-electrode current collector layer in stacked succession. The electrode layer has an electrode active material, and the counter-electrode layer has a counter-electrode active material. One of the electrode active material and the counter-electrode material is a cathodically active material and the other of the electrode active material and the counter-electrode material is an anodically active material. A subset of the unit cell population includes a pair of spacer members located between the electrode current collector layer and the counter-electrode current collector layer. At least a portion of the counter-electrode active material is located between the spacer members in a common plane defined by the x and z axes.

Abstract: An electrode assembly includes unit cells stacked in a longitudinal direction, each unit cell including an electrode structure, a separator, and a counter-electrode structure. The electrode structure includes an electrode current collector and an electrode active material layer. The counter-electrode structure includes a counter-electrode current collector and a counter-electrode active material layer. An end portion of the counter-electrode current collector extends past the counter-electrode active material and the separator. The end portion of the counter-electrode current collector is bent to define a bent end portion of the respective counter-electrode current collector. The bent end portions of at least some of the counter-electrode current collectors overlap the bent end portion of an adjacent counter-electrode current collector. The electrode assembly also includes a counter-electrode busbar extending across and attached to the bent end portions such that the counter-electrode current collectors are electrically connected to and are disposed inboard of the counter-electrode busbar.
