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 α-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 α-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.
