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.

摘要： A method for transferring carrier ions from an auxiliary electrode to an electrode assembly through a constraint system. The electrode assembly includes a population of unit cells that each includes an electrode structure, a counter-electrode structure, and an electrically insulating separator. The electrode assembly is enclosed within a volume defined by the constraint system comprising (i) first and second primary growth constraints separated in the stacking direction, and (ii) first and second secondary growth constraints separated in the vertical direction, wherein (iii) the first and secondary growth constraints are connected to upper and lower end surface(s) of the electrode or counter-electrode structures, and comprise a plurality of apertures having porous electrically insulating material disposed therein having a porosity in the range of from 20% to 60%. Carrier ions are transferred from the auxiliary electrode through the porous electrically insulating material to members of the unit cell population.
