Abstract
An alkali metal, such as sodium, sulfur cell having an alkali metal anode, a solid ionic electrolyte, such as sodium .beta. alumina, and a liquid catholyte formed by sulfur, a halosulfane, such as sulfur monochloride and a haloacid, such as aluminum chloride, is described.
Claims8
A cell comprising an alkali metal anode;
- a cathode, a solid ionic electrolyte, said electrolyte separating said anode and said cathode;
- characterized in that the active reactants of said cathode comprise halosulfanes and haloacids;
- said halosulfanes and said haloacids having molar ratios between 2:1 and 1:2, said active reactants forming a basic mixture for at least part of the charge/discharge cycle.
