  • Descrição: •Unique heterojunction structure and defect construction in MoSeS hybrids with a large layer space.•Strong multiscale coactions between each components.•High reversible capacity, superior rate capability and excellent cycling performances for AIBs. Architectural engineering emerges as a promising strategy for modulating the energy storage performance of electrode materials. In this study, the incorporation of the S element and a graphene matrix led to the formation of a unique heterojunction structure and defect construction in MoSeS hybrids, resulting in heightened electronic conductivity and increased active sites for aluminum storage. Experimental findings, coupled with density functional theory calculations, indicate that architectural engineering effectively reduces the energy barrier and mitigates structural changes during the diffusion of Al3+. Consequently, MoSeS exhibits an exceptionally high specific capacity of 291.8 mAh/g at a current density of 100 mA g−1, a remarkable rate performance of 106.2 mAh/g at 1000 mA g−1, and outstanding cycling stability with a retained capacity of 158.5 mAh/g over 1000 cycles at 150 mA g−1. The heterojunction structure and defect construction strategy offer an efficient means to tailor electrode materials for high-performance aluminum-ion storage.
