摘要：

Flower-like α-Fe 2 O 3-δ nanostructures have been successfully synthesized via a one-step hydrothermal method. The as-prepared α-Fe 2 O 3-δ nanostructures exhibited a good cyclability and rate performance. The discharge capacity could retain as high as 1192.4 mAh g -1 (current density: 400 mA g -1 ) after 800 cycles, which is higher than the theoretical value of hematite. When the current density increased to 3200 mA g -1 , the reversible capacity is about 660 mAh g -1 . The good electrochemical performance of α-Fe 2 O 3-δ nanostructures ...
