Abstract
A nanophase MnO 2 was synthesized using w/o microemulsion as reation media, The most favorable experiment conditions for the preparation of nm MnO 2 were researched. XRD,TEM,AC impedance, cyclic voltammetry etc. examinations were used to characterize the sample comparison with the classical MnO 2 (I.C.No.1EMD,electrolytic manganese dioxide). Sample shows that the crystal styucture of the synthesized samples are mainly γ MnO 2, with average particle size in the nanometer as shown by TEM. It was found that the discharge capacity of nm MnO 2 obtained is significantly higher than that of the I.C.No.1 EMD.
