“…The pristine AlPSs solution exhibits strong S 6 2− and S 4 2− peaks. [15,44] After the addition of the Cu 1 Co 1 @NC and Co@NC, the AlPSs peaks become weakened. Notably, the S 6 2− peak almost disappears with the presence of Cu 1 Co 1 @NC, confirming that the Cu processes strong adsorption toward AlPSs, especially the S 6 2− species.…”

Aluminum–Sulfur (Al–S) batteries are regarded as promising energy storage devices due to their high energy‐to‐price ratios and safety. However, they suffer from clumsy S ↔ Al2S3 reactions and short lifespans that limit their practical application. By combining the merits of adsorptive Cu, catalytic Co, and conductive N‐doped carbon matrix, the bimetals decorated N‐doped carbon (Cu1Co1@NC) enables smooth adsorption and conversion of polysulfides. Consequently, the S@Cu1Co1@NC exhibits excellent electrochemical performance (delivering a high capacity of 317.5 mAh g−1 after 320 cycles at 1.5 A g−1). Moreover, the Cu‐endowed strong Al affinity and robust 3D scaffold with Co‐enhanced conductivity can regulate Al3+ depositing/stripping and successfully suppress Al dendrites. As a result, the Cu1Co1@NC displays negligible Al nucleation overpotential and provides ultra‐long lifespan (>10 000 h) and exceptional reversible (Coulombic efficiency = 99.8–99.9%) Al3+ plating/stripping. Integrating all these advantages, a full Al–S cell constructed with Cu1Co1@NC as two‐in‐one hosts demonstrates excellent capacity retention with enhanced reversibility. This work provides insights into the design of promising Al–S batteries based on bifunctional CuCo bimetal and favorable 3D framework.

“…[56] Ju et al synthesized nitrogen and oxygen dualcoordinated single iron atoms in porous carbon (FeÀ NOÀ C) and investigated their roles for LiÀ S and AlSBs. [57] The stabilisation of aluminum polysulfides on FeÀ NOÀ C was achieved through dipole-dipole interactions, which were facilitated by the ineffective d-p hybridization. This interaction mechanism resulted in accelerated kinetics of the AlÀ S conversion and enhanced the catalytic performance in both directions.…”

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. In this review, we examine the current advancements in cathodes, both in theory and practice, as well as the progress made in aqueous and nonaqueous electrolytes. We also explore the modifications made to separators and the theoretical understanding of problems associated with AlSBs. Furthermore, we discuss future research directions aimed at resolving these issues. Our aim is to summarize the current progress in AlSBs and, based on recent progress and understanding of the mechanism, help design a battery to overcome the challenges that such batteries have been facing.

“…Aluminum metal batteries (AMBs) are potential energy storage devices complementary to the state-of-the-art lithium-ion batteries, due to the high theoretical capacity (2980 mA h g −1 , 8050 mAh cm −3 ), low cost, and high abundance of aluminum cathode side, materials that can adsorb polysulfides have been employed as the host material of sulfur to reduce the dissolution of polysulfides, [24][25][26], for example, heteroatom-functionalized and/or hierarchical porous carbonaceous materials, metalorganic frameworks (MOFs), boron nitrides, and Mxenes. [18,27] Catalysts that can further anchor the polysulfides and simultaneously promote the sluggish electrochemical conversion between S and Al 2 S 3 are also embedded to the aforementioned host materials, [28][29][30], for example, Mo 6 S 8 , [31] and TiN. [32] In addition to the cathode, electrolyte design approaches preventing the diffusion of polysulfides are also reported, resulting in remarkably enhanced cyclability.…”

Aluminum-sulfur batteries employing high-capacity and low-cost electrode materials, as well as non-flammable electrolytes, are promising energy storage devices. However, the fast capacity fading due to the shuttle effect of polysulfides limits their further application. Herein, alkaline chlorides, for example, LiCl, NaCl, and KCl are proposed as electrolyte additives for promoting the cyclability of aluminum-sulfur batteries. Using NaCl as a model additive, it is demonstrated that its addition leads to the formation of a thicker, Na x Al y O 2 -containing solid electrolyte interphase on the aluminum metal anode (AMA) reducing the deposition of polysulfides. As a result, a specific discharge capacity of 473 mAh g −1 is delivered in an aluminumsulfur battery with NaCl-containing electrolyte after 50 dis-/charge cycles at 100 mA g −1 . In contrast, the additive-free electrolyte only leads to a specific capacity of 313 mAh g −1 after 50 cycles under the same conditions. A similar result is also observed with LiCl and KCl additives. When a KCl-containing electrolyte is employed, the capacity increases to 496 mA h g −1 can be achieved after 100 cycles at 50 mA g −1 . The proposed additive strategy and the insight into the solid electrolyte interphase are beneficial for the further development of long-life aluminum-sulfur batteries.
