Abstract: 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%.

Abstract: A locking retainer includes a flexible band including an outer surface, an inner surface substantially parallel to and spaced from the outer surface, a first end, and a second end. A first plug member is integrally attached to the first end of the flexible band and includes an extending member having a first end, a second end, and top and bottom surfaces. The first plug member includes a first prong extending from the top surface of the extending member, and a second prong extending from the bottom surface of the extending member. A second plug member integrally attached to the second end of the flexible band comprises a first and second leg that each has a first end and a second end, wherein the second leg is substantially parallel to and spaced from the first leg. A cavity is defined between the first ends of the first and the second legs. The second ends of the first leg and the second leg are joined.
