“…The development of various aluminum–sulfur systems began in the 1980s. A nonaqueous aluminum–sulfur system was investigated by Marassi et al in 1977, while the aqueous aluminum–sulfur battery was initially proposed in 1993 by Licht et al Recently, Cohn et al proposed the first aluminum–sulfur cell fabricated using an aluminum‐metal anode and room‐temperature ionic liquid electrolyte of AlCl 3 in 1‐ethyl‐3‐methylimidazolium chloride and a sulfur/carbon composite cathode. This system can reach a high capacity of 1600 mA h g −1 and shows the potential to be electrochemically reversible .…”

that makes use of intercalation materials as the electrodes (Figure 1), applications involving electric vehicles and smart grids may require rechargeable batteries with new battery chemistries that can generate even higher energy densities for longer driving ranges and higher energy-storage capabilities. [6][7][8] Additionally, the lithiated transition-metal oxides used in commercial lithium-ion battery cathodes tend to be expensive, scarce, or toxic to the environment. Thus, it is desirable to explore new electrode materials that are naturally abundant (and therefore less expensive) as well as environmentally compatible in order to successfully enter the future battery markets. [6,[8][9][10][11] This driving force has promoted the development of batteries with conversionreaction electrodes, in which reversible electrochemical reactions take place and new chemical compounds form during the cycling of the battery. Naturally abundant materials, such as sulfur for the cathode, can be applied as electrodes. Different metallic anodes have shown great potential in coupling with sulfur cathode to generate a high energy density, including lithium metal [3,10,[12][13][14][15][16][17]31] as well as other alkali [18][19][20][21][22][23][24]31] and high-valent metals. [18,[25][26][27][28][29][30][31] As a next-generation energy-storage technology beyond lithium-ion batteries, lithium-sulfur batteries are the most promising low-cost, high-capacity energy-storage device available due to their high charge-storage capacity, low cost, and the wide availability of sulfur. [32][33][34][35] The electrochemical reactions of lithium-sulfur batteries involve reversible conversions between sulfur (S 8 ), lithium polysulfides (Li 2 S x , x = 4-8), and lithium sulfides (Li 2 S 2 and Li 2 S). [33][34][35][36] The conversions between sulfur and lithium polysulfides and lithium sulfides involve phase changes between liquid-state polysulfides and solid-state sulfur and sulfides. [35][36][37][38][39][40] Thus, the conversion reaction of lithium-sulfur battery chemistry has no restriction in maintaining the initial crystal chemistry of the electrode during electrochemical cycling. [39][40][41][42] Therefore, a full twoelectron redox reaction per sulfur atom can occur in a manner that is both reversible and stable, increasing the chargestorage capacity drastically as compared to the currently used insertion-reaction oxide cathodes. [7,[39][40][41][42] As a result, sulfur cathodes possess a high theoretical charge-storage capacity of 1672 mA h g −1 , which is the highest value among solid-state Lithium-sulfur batteries are a major focus of academic and industrial energystorage research due to their high theoretical energy density and the use of low-cost materials. The high energy density results from the conversion mechanism that lithium-sulfur cells utilize. The sulfur cathode, being naturally abundant and environmentally friendly, makes lithium-sulfur batteries a potential next-generation energy-storage technology. The current state of the rese...

“…Their low cost and high energy density give Al–S batteries potential for application in electric vehicles and large‐scale energy storage. Motivated by this potential, the aqueous Al–S battery was discovered as early as 1993, but research on such systems stagnated after 2002 because of several irresolvable drawbacks of aqueous systems, as in the case of aqueous AIBs . After a decade of silence, a primary nonaqueous Al–S battery based on chloroaluminate ILs was demonstrated in 2015 .…”

Aluminum-ion batteries (AIBs) are regarded as viable alternatives to lithium-ion technology because of their high volumetric capacity, their low cost, and the rich abundance of aluminum. However, several serious drawbacks of aqueous systems (passive film formation, hydrogen evolution, anode corrosion, etc.) hinder the large-scale application of these systems. Thus, nonaqueous AIBs show incomparable advantages for progress in large-scale electrical energy storage. However, nonaqueous aluminum battery systems are still nascent, and various technical and scientific obstacles to designing AIBs with high capacity and long cycling life have not been resolved until now. Moreover, the aluminum cell is a complex device whose energy density is determined by various parameters, most of which are often ignored, resulting in failure to achieve the maximum performance of the cell. The purpose here is to discuss how to further develop reliable nonaqueous AIBs. First, the current status of nonaqueous AIBs is reviewed based on statistical data from the literature. The influence of parameters on energy density is analyzed, and the current situation and existing problems are summarized. Furthermore, possible solutions and concerns regarding the construction of reliable nonaqueous AIBs are comprehensively discussed. Finally, future research directions and prospects in the aluminum battery field are proposed.

The electrochemical behavior of an Al anode in organic electrolytes was investigated. Common contemporary electrolytes for Li batteries were selected, based on their activity toward Al anodic dissolution. Significant improvement (anodic shift) of E Al/Al 3+ by up to 1 V occurs in several electrolytes, and can exhibit efficient coulombic oxidation of aluminum. Enhanced E Al/Al 3+ electrolytes include (C 2 H 5 ) 4 NCl (TEA), and AlCl 3 in γ-butyrolactone (BLA) and acetonitrile (ACN) solvents, forming solutions such as TEA/BLA, TEA/ACN, and concentration optimized AlCl 3 /KCl/BLA. γ-butyrolactone based electrolytes exhibit evidence of quasireversible Al activity creating possibilities for rechargeable batteries.
