In this paper,rod-like α-MnO_2 was successfully synthesized by immersing-annealing technique with the reproducible,low-cost,porous scobs and manganese compound as raw materials.The obtained sample was characterized using various analytical techniques such as X-ray diffraction(XRD),transmission electron microscopy(TEM),cyclic voltammetry(CV)and galvanostatic charge and discharge experiments.The results revealed that the as-made sample was rodlike α-MnO_2 and had capcitive characteristics in 1.0 mol·L~(-1) Na_2SO_4 electrolyte.
