“…These results demonstrated the potential of RABs for practical applications. To improve the performance of RABs, several kinds of cathode, including modified graphites,10–12 graphene nanosheets,13–15 carbon‐based materials,16–18 transition metal oxides,19–21 and metal sulfides,22–25 have been developed. However, the IL electrolyte has received much less attention.…”

Rechargeable aluminum batteries (RABs) are extensively developed due to their cost‐effectiveness, eco‐friendliness, and low flammability and the earth abundance of their electrode materials. However, the commonly used RAB ionic liquid (IL) electrolyte is highly moisture‐sensitive and corrosive. To address these problems, a 4‐ethylpyridine/AlCl3 IL is proposed. The effects of the AlCl3 to 4‐ethylpyridine molar ratio on the electrode charge–discharge properties are systematically examined. A maximum graphite capacity of 95 mAh g−1 is obtained at 25 mA g−1. After 1000 charge–discharge cycles, ≈85% of the initial capacity can be retained. In situ synchrotron X‐ray diffraction is employed to examine the electrode reaction mechanism. In addition, low corrosion rates of Al, Cu, Ni, and carbon‐fiber paper electrodes are confirmed in the 4‐ethylpyridine/AlCl3 IL. When opened to the ambient atmosphere, the measured capacity of the graphite cathode is only slightly lower than that found in a N2‐filled glove box; moreover, the capacity retention upon 100 cycles is as high as 75%. The results clearly indicate the great potential of this electrolyte for practical RAB applications.

“…All kinds of carbon materials exhibit a reversible capacity of 60–130 mA h g −1 and unparalleled cycle stability. Transition metal oxides, sulfides and selenides have been reported mainly including Co 3 O 4 , CuO, TiO 2 , SnO 2 , Co 3 S 4 , Co 9 S 8 , CuS, FeS 2 , MoS 2 , Mo 6 S 8 , Ni 3 S 2 , NiCo 2 S 4 , SnS 2 , TiS 2 , VS 2 , Cu 2−x Se and CoSe . These materials could provide a higher capacity, but the cycle stability is inferior than carbon materials.…”

In this paper, we designed a novel rechargeable Al−Ni battery. Nickel foil was firstly used as a cathode material for aluminum batteries and realized a reversible electrode reaction in a weak Lewis acidic electrolyte. Al−Ni battery can provide a high discharge capacity of more than 0.4 mA h cm−2 and exhibit excellent stability. Furthermore, the electrode reaction mechanism and proposed reasonable reaction equations of Al−Ni battery was studied deeply. We also explored the failure process of Al−Ni batteries and obtained the composition of side reaction products. This Al−Ni battery could offer a high reversible capacity of 0.66 mA h at a current density of 0.5 mA cm−2. Even at 1 mA cm−2, it still delivers a capacity of 0.415 mA h (0.27 mA h cm−2) after 100 cycles.

“…[11] Regarding the more promising rechargeable AIBs, previous studies demonstrated that the intrinsic hydrogenation over the Al anode and passive oxide layer formation in the aqueous system drastically reduced the battery voltage and efficiency, which lead to the sluggish development of rechargeable aqueous AIBs. [21][22] After then, AIBs have been attracting everincreasing attention in recent years. [20] However, the high operation temperature, electrode solubility, and Al dendrite hinder the practical application of such non-aqueous rechargeable AIBs.…”

“…[16] Till the 2010s, the mixture of M + X À and AlCl 3 ionic liquid (IL) electrolyte (where M + could be organic cations, such as imidazolium and pyrrolidinium, and X À represents Cl À , Br À , or I À ) was evidenced to act as efficient media for Al deposition and exfoliation at room temperature. [21][22] After then, AIBs have been attracting everincreasing attention in recent 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.
