Abstract

Separators for use in batteries are disclosed. In various embodiments, the separators include one or more of raised shoulders, ribs in three or more sizes, thickened mini-ribs on shoulders, and ribs within the shoulder. The disclosed separators are more resistant to failure due to punctures or tears than conventional separators.
