“…Reed and Menke reported that the V 2 O 5 nanowires were electrochemically inactive in the above AIB system, and the capacity was attributed to the reactions with the iron and chromium metal in the stainless steel current collector. While Gu et al demonstrated the reversible insertion/extraction of aluminum‐ion into V 2 O 5 nanowires. The surface amorphization of V 2 O 5 nanowires arises during the intercalation of Al 3+ ions (Figure c).…”

The emerging electrochemical energy storage systems beyond Li‐ion batteries, including Na/K/Mg/Ca/Zn/Al‐ion batteries, attract extensive interest as the development of Li‐ion batteries is seriously hindered by the scarce lithium resources. During the past years, large amounts of studies have focused on the investigation of various electrode materials toward emerging metal‐ion batteries to realize high energy density, high power density, and a long cycle life. In particular, vanadium‐based nanomaterials have received great attention. Vanadium‐based compounds have a big family with different structures, chemical compositions, and electrochemical properties, which provide huge possibilities for the development of emerging electrochemical energy storage. In this review, a comprehensive overview of the recent progresses of promising vanadium‐based nanomaterials for emerging metal‐ion batteries is presented. The vanadium‐based materials are classified into four groups: vanadium oxides, vanadates, vanadium phosphates, and oxygen‐free vanadium‐based compounds. The structures, electrochemical properties, and modification strategies are discussed. The structure–performance relationships and charge storage mechanisms are focused on. Finally, the perspectives about future directions of vanadium‐based nanomaterials for emerging energy storage devices are proposed. This review will provide comprehensive knowledge of vanadium‐based nanomaterials and shed light on their potential applications in emerging energy storage.

“…Aluminum metal, because of its high abundance, large gravimetric/volumetric energy density (2980 mAh g −1 and 8040 mAh cm −3 , respectively), and good safety, has been considered a promising anode material for electrochemical energy storage systems with high‐capacity cathode materials such as elemental sulfur (S 8 ). The Al‐S battery is of great interest owing to its high theoretical energy density (1300 Wh kg −1 ) and acceptable theoretical voltage of 1.229 V, which are much superior to those of Al ion battery systems . However, the slow kinetics of the charge/discharge processes of Al‐S batteries makes it very difficult to achieve a reversible electrochemical reaction between Al and S if S 8 is used .…”

An Aluminum–Sulfur Battery with a Fast Kinetic Response

The electrochemical performance of the aluminum-sulfur (Al-S) battery has very poor reversibility and a low charge/discharge current density owing to slow kinetic processes determined by an inevitable dissociation reaction from Al Cl to free Al . Al Cl Br was used instead of Al Cl as the dissociation reaction reagent. A 15-fold faster reaction rate of Al Cl Br dissociation than that of Al Cl was confirmed by density function theory calculations and the Arrhenius equation. This accelerated dissociation reaction was experimentally verified by the increase of exchange current density during Al electro-deposition. Using Al Cl Br instead of Al Cl , a kinetically accelerated Al-S battery has a sulfur utilization of more than 80 %, with at least four times the sulfur content and five times the current density than that of previous work.

“…The history of ABs could trace back to the 1850s when the first Buff cell was developed with Al as the anode. [19] Non-aqueous recharegeable AIBs based on molten salts, such as NaClÀ (KCl)À AlCl 3 , were developed with metal-chlorides/sulfide cathodes. [16][17][18] The primary Al-air battery and primary aqueous AIBs have achieved much progress these years.…”

As one of the most promising alternatives to next‐generation energy storage systems, aluminum batteries (ABs) have been attracting rapidly increasing attention over the past few years. In this review, we summarize the recent advancements of ABs based on both aqueous and non‐aqueous electrolytes, with a particular focus on rechargeable non‐aqueous ionic liquid‐based aluminum‐ion batteries (AIBs). Progress of the current intensive investigation on the development of cathode materials and electrolytes in non‐aqueous AIBs are discussed. Then research efforts towards aqueous ABs are described to give readers a broader view of the aluminum battery family. Finally, the review summaries the key challenges underpinning ABs and provides future research perspectives on this growing field.
