Preparation and Electrochemical Performance of Li 4 Mn 5 O 12 Nanorods using β -MnO 2 Nanorods as Precursor

Li4Mn5O12 nanorods were successfully prepared by using β-MnO2 nanorod precursors as self-templates. The obtained Li4Mn5O12 nanorods were approximately 0.8–1.5 μm in length and 0.15 μm in width, and were employed as electrode materials and applied in supercapacitors. The results show that Li4Mn5O12 nanorods can deliver 211 F g−1 within the potential range of 0–1.4 V at a scan rate of 5 mV s−1 in 1 mol L−1 Li2SO4 solution, which presents a good electrochemical performance.
