Abstract

Hierarchical porous ZnCo2O4 microspheres have been successfully synthesized via a solvothermal method followed by an annealing process. The ZnCo2O4 electrode shows a high specific capacitance of 647.1 F g−1 at 1 A g−1 and 440.6 F g−1 at 10 A g−1 in 2 M KOH. After 2000 cycles, the capacity loss is only 8.5%.
