A SODIUM ELECTRODE ENERGY CONVERSION DEVICE AND A METHOD OF CLOSING THE CASE OF A SODIUM ELECTRODE ENERGY CONVERSION DEVICE

摘要

A sodium electrode energy conversion device includes a case closed by a closure member. The case and the closure member are sealed together at interfacing surfaces thereof. At least one of the case and the closure member is formed from a composite material comprising a metal substrate and a layer of a metal more ductile than the substrate on at least the interfacing surface of the substrate. The case and the closure member are joined together by a roll seam joint.
