Liquid sulfur alum battery energy storage

Can aluminum-sulfur batteries be used as energy storage systems?

Aluminum-sulfur batteries (AlSBs) exhibit significant potential as energy storage systems due to their notable attributes, including a high energy density, cost-effectiveness, and abundant availability of aluminum and sulfur. In order to commercialize AlSBs, an understanding of their working principles is necessary.

Are aluminum-sulfur batteries a 'beyond lithium'?

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).

What is the sulfur loading of al-s batteries?

The sulfur loading was ∼1.0 mg cm −2. The Al-S batteries were prepared with a coin-cell configuration. The cathode-separator assembly was prepared as schematized in Figure S1. The sulfur/CNF cathode was covered with a piece of SWCNT-coated GF separator (Figure S2).

Are aluminum-sulfur batteries reversible?

Although lithium-sulfur batteries have been extensively investigated in recent years, aluminum-sulfur (Al-S) chemistry is more attractive from an economical, sustainability, and safety point of view. However, because of a lack of effective electrolytes, only limited reversibility has been realized so far with Al-S chemistry.

Can a sulfur cathode be used in an al-s battery?

However, because of the extremely low cost of Al, the energy cost of the Al-S battery is only about one-tenth of that of Li-S batteries. 43 Therefore, coupling an earth-abundant aluminum anode with a sulfur cathode would lead to an aluminum-sulfur (Al-S) battery that could offer a high-energy-density, low-cost, and safe energy storage system.

Which chemistry is best for a lithium-sulfur battery?

Ambient-temperature non-aqueous sulfur battery chemistries are becoming increasingly appealing for these applications. Although lithium-sulfur batteries have been extensively investigated in recent years, aluminum-sulfur (Al-S) chemistry is more attractive from an economical, sustainability, and safety point of view.
