In this paper, α-MnO2 nanorods were successfully synthesized by chemical solution route with the reproducible,low-cost, porous sawdust as template.The obtained samples were characterized by TEM, FT-IR and XRD tests. The results of the tests showed that the samples were α-MnO2 nanorods with diameters of about 10nm and with lengths up to 150 nm. The super electrochemical characteristics of the samples were characterized by cyclic voltammetry (CV) and constant current charge-discharge tests (CH/DCH). The results demonstrated that α-MnO2 nanorods had excellent electrochemical performance in 1.0 mol?L-1 (NH4)2SO4 electrolyte within the potential range of 0～1.0 V (vs.SCE). The initial specific capacitance of single MnO2 electrode reached 176 F譯-1 and 138F譯-1 at the current of 5 mA and 10 mA respectively.
