As the world becomes more concerned about climate change and the need for clean energy, there is an increasing demand for the development of new battery technologies [1–4]. Although lithium-ion batteries (LIBs) are currently the most widely used, they have some limitations such as cost, pollution, and safety concerns [5–8]. The lack of suitable electrode materials previously hindered the development of aluminum-ion batteries as a promising alternative energy storage system [9–11]. However, with advancements in the electrode technology, there is renewed interest in aluminum-ion batteries as a low-cost and high-performance energy storage solution. Recently, Sadoway’s group published a research article that presented a promising alternative to LIBs based on aluminum-chalcogen batteries with a molten chloroaluminate electrolyte [12]. This battery technology has a high energy density and fast-charging capabilities, making it a strong candidate for large-scale energy storage applications [12].
