This mini-review discusses the use of transition metal dichalcogenides (TMDs) as cathode materials for rechargeable aluminum-ion batteries (AIBs). AIBs are promising candidates for energy storage due to their high theoretical capacity, abundance, and safety. However, the electrochemical performance of AIBs is limited by the lack of suitable cathode materials. TMDs, such as MoS₂, MoSe₂, WS₂, WSe₂, VS₂, and VSe₂, have shown great potential as cathode materials due to their large surface area, high theoretical capacity, and fast ion/electron transport kinetics. These materials have a layered structure with weak van der Waals interactions between layers, which facilitates the intercalation and de-intercalation of Al³+ ions. Recent studies have demonstrated that TMD-based cathode materials can achieve high discharge capacities and excellent cycling stability. For example, MoS₂ and MoSe₂ have been used to fabricate high-performance AIBs with capacities exceeding 200 mAh g⁻¹. Additionally, the use of 3D printing techniques has enabled the fabrication of complex electrode structures with high surface areas and improved ion transport properties. These techniques allow for the precise design of electrodes with tailored geometries, which can enhance the electrochemical performance of AIBs. Despite their potential, TMD-based AIBs face challenges such as poor structural stability, irreversible reactions, and low coulombic efficiency. Future research should focus on improving the structural stability of TMDs, developing new cathode materials with high active surface areas, and optimizing the electrolyte composition to enhance the performance of AIBs. The integration of 3D printing technologies with TMD-based materials offers a promising approach to overcome these challenges and advance the development of high-performance AIBs.This mini-review discusses the use of transition metal dichalcogenides (TMDs) as cathode materials for rechargeable aluminum-ion batteries (AIBs).
