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.
Claims11
In a sodium/sulfur electrochemical cell or battery having at least one anode chamber with anodic reactant and at least one cathode chamber with cathodic reactant and separated from each other by a sodium ion conducting solid electrolyte and having a cathodic current collector in contact with the cathodic reactant, the improvement comprising said cathodic current collector comprising a boronized surface in contact with said cathodic reactant and an additional boron source in physical proximity to said boronized surface.
