A carbon-coated shuttle-like Fe₂O₃/Fe_1-x S heterostructure derived from metal-organic frameworks with high pseudocapacitance for ultrafast lithium storage.

ABSTRACT: Pursuing active, low-cost, and stable electrode materials with superior rate capability and long-life cycling performances for lithium-ion batteries remains a big challenge. In this study, a carbon-coated shuttle-like Fe₂O₃/Fe_1-x S heterostructure is synthesized by simply annealing Fe-based metal-organic frameworks (MIL-88(Fe)) as precursors and sublimed sulfur. Carbon-coated Fe₂O₃/Fe_1-x S displays a unique structure with ultrafine Fe₂O₃/Fe_1-x S nanoparticles distributed in the hollow and porous carbon matrix, which offers a large specific surface area and fast charge transfer ability, and alleviates the volume change upon cycling. When evaluated as an anode material for
