| Abstract: | Zr-doped Co3O4 electrode materials were prepared by the reverse microemulsion method,and their capacitive properties were studied.The results show that the prepared Co3O4 powder is composed of spherical powders with cubic crystal structure.When the mole fraction(x) of Zr is in the range of 1% to 3%,Zr doping decreases the grain size of Co3O4 electrode materials;while when x is in the range of 1% to 5%,Zr doping enhances the reversibility,increases the specific capacitance and extends the working life of Co3... |
