摘要：
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%.
