Sodium-sulfur battery, and a battery system using same |
摘要 |
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 made of a Co base alloy containing Cr, Ni, and Mo, wherein carbide containing at least one of Cr, W, and Mo is precipitated, or the cell container for positive electrode is assembled by integrating plural members made of a high corrosion resistance alloy containing Cr by welding, and a readily deformable portion is provided to the cell container for positive electrode, whereby the reliability of the sodium-sulfur battery can be significantly improved.
