ABSTRACT:
A stable, long life sodium/sulfur electrochemical cell or battery wherein the cathodic current collector has a boronized surface in contact with the cathodic reactant and an additional boron source in physical proximity to the boronized current collector surface. In one embodiment, the cathodic current collector is the can or electrode container thereby providing a stable, long life cell casing protected from corrosion effects.
