Abstract
Examples disclosed herein relate to a continuous separator having perforations to help reduce or prevent wrinkling of the separator when producing curved electrode stacks. One example provides a battery comprising a plurality of discontinuous electrode layers, and a continuous separator separating the discontinuous electrode layers, the continuous separator having perforations extending at least partially through a depth of the continuous separator in a folded region of the continuous separator.
