The new battery architecture uses aluminum and sulfur as its two electrode materials, with a molten salt electrolyte in between. As the price of lithium skyrockets due to increasing demand, the world needs inexpensive alternatives. Aluminum and sulfur are plentiful and cheap.
So far, the publications on Al-S batteries mostly reported ex-situ studies of the Al-ion electrolyte and the sulfur cathode during cycling. After discharge, it has been determined the presence of all possible sulfur species, i.e. elemental sulfur, S 82−, S 62−, S 42−, S 22− and S 2−.
Molten salt aluminum-sulfur batteries are based exclusively on resourcefully sustainable materials, and are promising for large-scale energy storage owed to their high-rate capability and moderate energy density; but the operating temperature is still high, prohibiting their applications.
Among the plethora of contenders in the ‘beyond lithium’ domain, the aluminum–sulfur (Al–S) batteries have attracted considerable attention in recent years due to their low cost and high theoretical volumetric and gravimetric energy densities (3177 Wh L −1 and 1392 Wh kg −1).
