Nano-MnO_2 was synthesized by reacting on the interface between ethyl acetate and water with KmnO_4 and MnSO_4 as raw materials. The XRD, IR and SEM analyses showed the prepared MnO_2 was the mixed phase of α and γ crystal type,compesed of some small and uniform nanoreds. The dcctrochemical performance tests showed the MnO_2 electrode had fine capacitance behavior in 6 mol/L KOH,its specific capacitance could reach 243 F/g. The special nano-strueture was beneficial to its heavy load discharge.
