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/Fe1−xS heterostructure is synthesized by simply annealing Fe-based metal–organic frameworks (MIL-88(Fe)) as precursors and sublimed sulfur. Carbon-coated Fe2O3/Fe1−xS displays a unique structure with ultrafine Fe2O3/Fe1−xS 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 lithium-ion batteries, it exhibits an ultra-high specific capacity of 1200 mA h g−1 at 0.1 A g−1, and superior high rate capability with a capacity of 345 mA h g−1 at a very high current density of 5.0 A g−1 owing to its high electrical conductivity and enhanced pseudocapacitive contribution from surface effects. The current strategy is promising to synthesize the carbon-coated porous structure from metal–organic frameworks for next-generation energy-storage applications.
