Abstract

Metall oxides have been proven to be potential candidates for the anode material of lithium-ion batteries (LIBs) because they offer high theoretical capacities, and are environmentally friendly and widely available. However, the low electronic conductivity and severe irreversible lithium storage have hindered a practical application. Herein, we employed ethanolamine as precursor to prepare Fe₂O₃/COOH-MWCNT composites through a simple hydrothermal synthesis. When these composites were used as electrode material in lithium-ion batteries, a reversible capacity of 711.2 mAh·g^-1 at a current density of 500 mA·g^-1 after 400 cycles was obtained. The result indicated that Fe₂O₃/COOH-MWCNT composite is a potential anode material for lithium-ion batteries.
