“…AIBs comprise of a metallic aluminum that serves as the anode and the negative current collector, a chloroaluminate ionic liquid as the electrolyte with a AlCl 3 :EMImCl molar ratio (r)>1 (only in this cases reversible electrodeposition of metallic Al is possible), an Al‐insertion cathode material and a positive current collector. The vast majority of studies have been mainly focused on increasing energy density through the development of new cathode materials, e. g. vanadium oxides, metals sulfides, polymers, MXene, tellurium or graphitic materials amongst others . Most of these studies were carried out using expensive or unpractical materials like glassy carbon, molybdenum (Mo),, tungsten (W), or tantalum (Ta), due to the anodic dissolution of cheap and commonly used current collectors, e. g. Ni, Cu, Ti or stainless steel.…”

Rechargeable aluminum‐ion batteries (AIBs) are emerging as a promising energy storage technology. However, a series of issues will need to be addressed for the commercialization of AIBs. Anodic dissolution of cheap materials commonly used as cathode current collectors is a great challenge. At laboratory scale, this issue is solved by using expensive/scarce current collectors. The aim of our work is twofold. 1) To quantify the impact of the current collector in the battery cost by performing a cost analysis, which reveals that the current collector is currently the most expensive element in AIBs. 2) To propose the use of carbon‐based current collectors, such as gas diffusion layers (GDLs), which are shown to be an excellent option for AIBs. From an electrochemical perspective, the GDL does not corrode and does not catalyze electrolyte decomposition. Moreover, performances of AIBs using GDLs as current collectors are comparable to those using more expensive state‐of‐the‐art materials, while its use contributes to reducing battery costs.

Aluminum‐ion batteries (Al‐ion batteries) have become a potential energy storage system, owing to their excellent cycling performance, three‐electron‐redox properties, and safety performance. Until now, great progress has been made in Al‐ion batteries. However, the Al‐ion battery system still encounters various problems, such as high electrolyte price, harsh working environment, low discharge platforms, and inferior capacity. Here, we prepared a novel Al‐ion battery with AlCl3/Imidazole hydrochloride (ImidazoleHCl) as the electrolyte, aluminum as the negative electrode, and commercial graphite as the positive electrode. The battery achieves a high specific discharge capacity of 129 mA h g−1 at a current density of 0.5 A g−1 and 105 mA h g−1 with a high coulombic efficiency of 99 % at the current density of 4 A g−1 after 1000 cycles. The mechanism of AlCl4− intercalation/de‐intercalation is proved by Raman, XRD and EDS studies. ImidazoleHCl is a promising electrolyte and this work provides a new insight for the Al‐ion battery system.

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.
