Anode Design for High-Performance Aluminum Batteries: Challenges and Strategies
Because of the advantages of aluminum including high volumetric/gravimetric capacity, high safety, and low cost, aluminum batteries have become one of the most attractive new electrochemical energy storage devices. High-performance battery materials are the bottleneck issues impeding the development of aluminum batteries. Compared with various cathode materials, the design of aluminum anode is a common key technology for aluminum batteries. However, the current aluminum anodes still suffer from diverse problems such as surface passivation, local corrosion, and dendrite growth, which greatly influence the electrochemical performance of aluminum batteries. In this review paper, targeting on these problems, we first analyze the key factors governing the electrochemical performance of anode from the viewpoint of reaction mechanisms. Then, we summarize recent important progress about the aluminum anode design, analyze the critical strategies for optimizing aluminum anodes, and discuss their optimization effect and mechanism. Finally, perspectives on the crucial challenges and development trends of aluminum anodes are presented, with a hope to shed light on the design of high-performance aluminum batteries.
