Abstract

In this paper, we present a fast and green method to prepare Li_0.44MnO₂ nanorods by Li/Na ion exchange of Na_0.44MnO₂ templates. XRD and SEM confirm that the products still maintain the crystal and geometric structure of Na_0.44MnO₂ temples. Electrochemical tests show the capacity of Li_0.44MnO₂ 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 Li_0.44MnO₂ nanorods have a potential application in the next generation of advanced batteries.
