摘要：

Electrolytic and electrodic effects are investigated for a novel aluminum/sulfur battery based on concentrated polysulfide catholytes and an alkaline aluminum anode. The battery is expressed by aluminum oxidation and aqueous sulfur reduction for an overall battery discharge consisting of: 2Al+S(4)2-+2OH-+4H2O-->2Al(OH)3+4HS- E(cell)=1.79V The theoretical specific energy of the Al/S battery (based on potassium salts) is 647 Wh kg-1. A first generation aluminum/sulfur battery is demonstrated with an open-circuit voltage of 1.3 V, and a specific energy of 110 Wh kg-1.
