Preparation and Electrochemical Performance of Li4Mn5O12 Nanorods using β-MnO2 Nanorods as Precursor

Li 4 Mn 5 O 12 nanorods were successfully prepared by using β-MnO 2 nanorod precursors as self-templates. The obtained Li 4 Mn 5 O 12 nanorods were approximately 0.8–1.5 μ m in length and 0.15 μ m in width, and were employed as electrode materials and applied in supercapacitors. The results show that Li 4 Mn 5 O 12 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 Li 2 SO 4 solution, which presents a good electrochemical performance.
