Fe2O3 Nano-particles Grown on Carbon Fabric as a Freestanding Anode for High-Performance Lithium-Ion Batteries

Advanced anode materials for high power and high energy have attracted great interest due to the increasing demand for energy conversion and storage devices. Fe2O3 possess high theoretical capacities, but poor electrochemical performances owing to their severe volume change during cycles. In this work, we develop a self-assembly approach for the synthesis of Fe(2)O(3 )nano-particles grown on carbon fabric by hydrothermal process. Compared with powder Fe2O3-based negative electrode materials, Fe2O3 nano-particles grown on carbon fabric show excellent potential in the next generation of pseudo-capacitor and flexible lithium-ion batteries. And these special anode materials without binder and conductive agent, it can provide larger space and specific surface area, and facilitate Li+ transmission and electrolyte penetration. When applied as an anode material for lithium-ion batteries, the Fe(2)O(3 )nano-particles manifest superior electrochemical lithium storage properties in terms of high reversible capacity, stable cycling capacity retention, and good rate capability.
