Aqueous rechargeable aluminum battery – a mini review
ab
Abstract
Recently, rechargeable aqueous aluminum ion batteries (RAAIBs) have been a promising candidate as the next-generation secondary battery in the rechargeable battery industry owing to its enhanced theoretical specific energy, low cost, and environmental friendliness. The manufacturing cost and price of battery components are very low because they can be prepared in ambient atmosphere and have a simple manufacturing process, which is advantageous compared to other battery types. Furthermore, the raw materials that comprise the battery's components are easily available and not expensive. However, currently its inferior cycle stability precludes real industrial application. In this article, the current progress in development of RAAIBs is briefly summarized based on the type of aluminum salt, including aluminum fluoride, chloride, sulfide, nitride, and others. Additionally, research areas necessary for improving the electrochemical performance of RAAIB will be discussed.
