Abstract: In this paper,MnO 2 nanophase powders are successfully prepared by the redox reaction in solid state. Their morphology,particle size, thermal stability and electrochemical properties are characterized and discussed by x ray diffraction (XRD), TEM,TG/DTA, CV,and constant current discharge.

Key words: solid phase synthesis, cyclic voltammetry, nanophase powders, constant current discharge
