Abstract

An electrochemical cell is provided comprising a first electrode and a second electrode. A separator, which includes an expansion joint, surrounds and seals the first electrode. The separator may comprise a first major surface and a second major surface substantially opposite the first major surface, and the expansion joint may be coupled between the first major surface and the second major surface.
