Recent progress in MXene-based electrode materials for aluminum-ion battery: A comprehensive review

Aluminum-ion batteries (AIBs) represent a promising frontier in energy storage technology, offering advantages in terms of cost-effectiveness, safety, and environmental impact. One drawback is the hindrance in reversible intercalation and rapid transportation of Aluminum ions due to the strong electrostatic attractions between highly charged Al3+ and the electrode. However, the advancement in aluminum-ion based batteries is, therefore, restricted by the lack of adequate materials for electrode that can reversibly intercalate Al3+ and provide long cycling stability. MXenes, emerging 2D materials, possess significant promising applications for energy storage as they offer outstanding electrical conductivity, extensive surface area, along with robust mechanical properties. In the present article, we provide the progress and achievements of MXene-based electrodes in AIB. This review explores the crucial role of MXenes in combination with a variety of active materials for cathodes, including both inorganic and organic, in addition to metallic anodes. We also provide an overview of the strategies used to design composite structures for electrode applications. By offering a comprehensive view of MXenes as multifunctional material in aluminum-ion batteries, this work intent to provide valuable findings for future research and innovation in the field.
