Due to their advantages of a high voltage, high specific capacity, long cycling life, low pollution, etc., lithium-ion batteries are widely used in consumer electronics, such as smart phones and laptops. Fe2O3 is chosen as the object of study in this work. Combining Fe2O3 with RGO allows for combining the advantages of a high specific surface area, high stability and high electrical conductivity to produce a new material for high-performance cathodes. The Fe2O3/RGO composite exhibits a remarkably high reversible specific capacity of 1582 mAh/g with a specific discharge capacity of 812 mAh/g at 0.1C after 100 cycles.
