Abstract
A highly reliable sodium-sulfur battery includes a cell container for the positive electrode which is hardly deteriorated by corrosion. The cell container for the positive electrode is assembled by integrating plural members made of a high corrosion resistant alloy containing Cr, or a Co base alloy containing Cr, Ni and Mo, wherein carbide containing at least one of Cr, W and Mo is precipitated, and a readily deformable portion is provided to the cell container for the positive electrode, whereby reliability of the sodium-sulfur battery can be significantly improved.
