The author has introduced an ambient temperature aluminum sulfur battery based on an aluminum anode and a polysulfide or solid sulfur cathode. The discharge of the aluminum/solid sulfur battery may be expressed as: 2Al + 3S + 3KOH + 3H{sub 2}O {yields} 2Al(OH){sub 3} + 3KHS; E{sub cell} = 1.8 V. 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. In this study the authors discuss electrochemical action and report on discharge characteristics of the aluminum sulfur battery in a variety of alkaline and polysulfide media as well as polysulfide and sulfur cathodic and aluminum anodic effects of the battery.
