英文摘要Spinel structure Co-doped ZnMn2O4 nanocrystals were successfully synthesized by a hydrothermal method. The effects of Co-doping concentration on the structure and electrochemical properties of the samples were investigated. The experimental results manifest that all samples exhibit a single-phase with a tetragonal structure, and morphologies are regular hollow microspheres. Cyclic voltammetry curves for all samples are similar to a rectangular shape with symmetric nature and no obvious redox peak. Galvanostatic charge-discharge curves were triangular and symmetric. Impedance spectra revealed that Zn1-xCoxMn2O4 possess low resistance. Better electrochemical properties of the ZnMn2O4 electrode could be obtained when the Co-doping ratio is 0.3. Zn0.7Co0.3Mn2O4 exhibits much higher specific capacitance (306 F g(-1)) at a scan rate of 5 mV s(-1), and shows excellent cycling stability and retains 98.2% of its initial capacitance after 1000 cycles. The enhanced capacitive performance in this work can be attributed to the incorporation of Co ions doped into the ZnMn2O4 host lattice.
