Current Challenges, Progress and Future Perspectives of Aluminum-Ion Batteries

Today, the ever-growing demand for renewable energy resources urgently needs to develop reliable electrochemical energy storage systems. The rechargeable batteries have attracted huge attention as an essential part of energy storage systems and thus further research in this field is extremely important. Although traditional lithium-ion batteries (LIBs) have a wide range of applications, they still face a number of challenges associated with the high cost, safety, transportation, aging effect and sensitivity to temperature. To meet these demands, it is essential to pave the path toward post lithium-ion batteries. Aluminum-ion batteries (AIBs), which are considered as potential candidates for the next generation batteries, have gained much attention due to their low cost, safety, low dendrite formation, and long cycle life. In addition to being the third most abundant element in the Earth's crust, aluminum is also cheap and has a high volumetric capacity of 8046 mAh cm–3. This review discusses the development of high-performance electrode materials for AIBs. Additionally, an overview of some challenges related to the utilization of electrode and electrolyte materials in AIBs has been provided.
