Abstract
A secondary battery assembly includes an electrode assembly having mutually perpendicular transverse, longitudinal, and vertical axes corresponding to X, Y and Z axes, respectively. A constraint is disposed on an outer surface of the electrode assembly. At least one of the electrode assembly or constraint has a protrusion extending in an X-Y plane defined by the X and Y axes and having a first radius of curvature in the X-Y plane. A battery enclosure encloses the electrode assembly and the constraint. An enclosure protection layer is disposed over at least a portion of the protrusion and between the protrusion and the battery enclosure. The enclosure protection layer defines a second radius of curvature overlying the first radius of curvature in the X-Y plane. The second radius of curvature is greater than the first radius of curvature to thereby reduce the potential of the protrusion causing damage to the battery enclosure.
