Layer Structured α-Fe2O3 Nanodisk/Reduced Graphene Oxide Composites as High-Performance Anode Materials for Lithium-Ion Batteries

A composited anode material with combined layered alpha-Fe2O3 nanodisks and reduced graphene oxide was produced by an in situ hydrothermal method for lithium-ion batteries. As thin as about 5-nm-thickness alpha-Fe2O3 nanosheets, open channels, and face-to-face tight contact with reduced graphene oxide via oxygen bridges made the composite have a good cyclability and rate performance, especially at high charge/discharge rates.
