Recently the authors introduced a new battery utilizing a sulfur cathode and aluminum anode. The Aluminum Sulfur cell, E{sub cell} (theoretical) = 1.8 V: 2Al + 3S + 3KOH + 3H{sub 2}O {r_arrow} 2Al(OH){sub 3}+3KHS. Faradaic capacity of the Al/S battery (based on potassium salts) is 505 Ah/kg, and the theoretical specific energy is: 1.8 Volt {times} 505 Ah/kg = 910 Wh/kg. The principal advantages of the system include its ability to function at and near room temperature, and the very high energy capacity of the anodic and cathodic materials. In this paper technological developments in the low, medium and high power density domains of the Aluminum/Sulfur Battery are discussed.
