RESUMO
In this paper, we present a fast and green method to prepare Li0.44MnO2 nanorods by Li/Na ion exchange of Na0.44MnO2 templates. XRD and SEM confirm that the products still maintain the crystal and geometric structure of Na0.44MnO2 temples. Electrochemical tests show the capacity of Li0.44MnO2 nanorods is up to 218 mAh · g-1 at the current density of 0.1 A · g-1. Especially, the capacity of electrode is still located at 90 mAh · g-1 at the current density of 5.0 A· g-1 after cycling for 100 times. So Li0.44MnO2 nanorods have a potential application in the next generation of advanced batteries.
